What is Bitcoin Halving and how does it affect the cryptocurrency?
25/02/2024The term "Halving" in the context of Bitcoin refers to a scheduled event in the cryptocurrency protocol, in which the reward for mining blocks is reduced by half. This event occurs approximately every four years and has a significant impact on the supply and demand of Bitcoin. During Halving, the number of new Bitcoins created per block is halved. This implies a decrease in the issuance rate of the cryptocurrency, which in turn can have an effect on the price and volatility of Bitcoin. Many analysts and experts are speculating about the long-term implications of the Halving and its influence on the cryptocurrency markets. Services related to Bitcoin Halving There are various types of services and tools related to Bitcoin Halving that can be beneficial for different actors in the cryptocurrency ecosystem. These services include: 1. Halving analysis and forecast This type of service provides detailed information about the past, present and future of the Bitcoin Halving. Through analysis and forecasting, it helps investors and cryptocurrency enthusiasts make informed decisions on how to position themselves before and after the event. 2. Bitcoin Mining As the reward in Bitcoin decreases, mining this cryptocurrency becomes more challenging. Bitcoin mining services offer solutions and advice to maximize mining efficiency and profitability, even in a low reward environment. 3. Financial advice related to Halving As the issuance rate of Bitcoin slows, investors may need to adapt their investment strategies. Financial advisory services specialized in cryptocurrencies and Bitcoin provide personalized recommendations and analysis to optimize investment performance in this context. 4. Development of tools for cryptocurrencies The Bitcoin Halving may generate changes in the cryptocurrency ecosystem, which may require the creation of new tools and solutions. Companies specialized in software development and applications related to cryptocurrencies can provide development and consulting services to adapt to these new demands. Bitcoin: Reward Reduction and Its Implications on the Cryptocurrency Ecosystem Bitcoin, the most famous and valuable cryptocurrency in the world, has periodically experienced an event known as a "reward reduction" or "Halving", which has significant implications on the cryptocurrency ecosystem. In this article, we will explore in depth what Bitcoin reward reduction is and how it affects both miners and investors. What is Bitcoin reward reduction? Bitcoin reward reduction is a scheduled event integrated into the cryptocurrency protocol. It occurs approximately every four years and consists of a halving of the reward miners receive for validating transactions and adding new blocks to the Bitcoin blockchain. Originally, when Bitcoin was launched in 2009, miners received a reward of 50 Bitcoins for each block mined. However, due to the reward reduction process, this amount has decreased over time. In 2012, it was reduced to 25 Bitcoins per block, in 2016 to 12.5 Bitcoins per block, and in 2020 it was reduced again to 6.25 Bitcoins per block. Implications for Bitcoin miners Bitcoin's reward reduction has a significant impact on mining the cryptocurrency. With each reduction, miners receive fewer Bitcoins for their work, which means less direct monetary reward. This may result in some miners leaving the Bitcoin network, especially those with higher electricity and mining equipment costs. On the other hand, those miners who manage to adapt and remain profitable even with a lower reward are rewarded with a larger share of the Bitcoin supply generated through mining. This concentration of Bitcoins in the hands of fewer miners can have effects on the decentralization and security of the network, since the number of active participants in the transaction validation process is reduced. Implications for investors and the price of Bitcoin Bitcoin's reward reduction also has implications for the price and supply of the cryptocurrency. As the issuance of new Bitcoins decreases, the supply in the market reduces. This may lead to higher relative demand if Bitcoin demand continues to grow or remains stable. In previous reward reduction events, a long-term increase in Bitcoin price has been observed. This is because the decrease in the supply of new Bitcoins can lead to greater perceived scarcity and therefore an increase in their value. However, it is important to note that the price of Bitcoin is highly volatile and can be influenced by a variety of external factors, so a continued increase after reward reduction cannot be guaranteed. Bitcoin's reward reduction is a key event in the life of the cryptocurrency and has implications for both miners and investors. As the number of new Bitcoins generated is halved, miners must adapt to remain profitable and the supply of Bitcoin on the market may decrease. However, this event can also have a positive impact on the price of Bitcoin in the long term. It is important to understand and take these factors into account when evaluating investment potential in Bitcoin and the cryptocurrency market in general. Bitcoin and limited supply: a unique combination Bitcoin has captured the attention of the financial world like no other cryptocurrency. One of its most notable features is its limited supply, meaning that only a finite number of bitcoins will be created in the world. This contrasts with traditional fiat currencies, which can be printed at the discretion of governments. How does Bitcoin limited supply work? Bitcoin was designed to have a total supply of 21 million coins. As new blocks are mined by users and added to the Bitcoin blockchain, new coins are generated and distributed as rewards to miners. However, this reward is halved in an event known as "Halving", which occurs approximately every four years. Halving ensures that the rate of issuance of new bitcoins decreases over time, following a predictable mathematical function. Currently, the reward per mined block is 6.25 bitcoins, but this number is expected to reduce further in the future. This controlled scarcity mechanism is a central part of Bitcoin's monetary policy. Advantages of Bitcoin Limited Supply Bitcoin's limited supply has several significant advantages: Sense of scarcity: The limitation in the supply of Bitcoin makes it a scarce and valuable asset. As it approaches its maximum supply, demand and price are expected to increase. Inflation Protection: Unlike fiat currencies, Bitcoin cannot be inflated or devalued at the discretion of governments. Its limited supply protects it from inflation and makes it a safe store of value. Monetary stability: With carefully controlled supply, Bitcoin offers greater monetary stability compared to national currencies, which can be affected by political and economic decisions. Challenges and debates surrounding the limited supply of Bitcoin Despite the advantages, Bitcoin's limited supply has also generated debates and challenges. Some argue that the scarcity of bitcoins could hinder its mass adoption as an everyday currency. Price volatility is also an issue of concern. Furthermore, the fact that only about 80% of all existing bitcoins have been mined raises questions about how the latest bitcoins will be distributed and how this will affect the network and its sustainability in the future. Bitcoin has revolutionized the financial world with its limited supply and unique monetary policy. Controlled and predictable scarcity is an essential part of its design, providing a solid alternative to traditional fiat currencies. Although limited supply can pose challenges and debates, it also offers significant benefits, such as a sense of scarcity, protection against inflation, and monetary stability. As Bitcoin continues to mature and its supply approaches its maximum limit, its value and relevance in the financial world continues to grow, leaving investors and enthusiasts with great anticipation about its future.

Madrid taxis already accept payment with cryptocurrencies
24/05/2022From this month of May, Madrid taxi users will be able to pay in cryptocurrencies. The possibility of this new means of payment comes after the agreement between the taxi sector and the Woonkly company, which has distributed dataphones to all taxi drivers so that payment with cryptocurrencies can be made. Madrid is the first city in Spain to introduce this means of payment in taxis, which is also contemplated by various municipalities in the United Kingdom and the Scandinavian countries. At the moment, the cryptocurrencies accepted in Madrid taxis are Ethereum, Bitcoin BEP2, Woonkly Power, Binance Coin, Cardano, Avalanche, Binance USD, Polkadot, USD Coin, Tether and Wrapped BN. The technology of the dataphones that are prepared to print the proof of the operation once the payment has been made, belongs to Waynance, a firm from Alicante, whose payment gateway has become the first universal payment system for cryptocurrencies. It allows payments done from any payment platform (POS, e-commerce, etc.), with any cryptocurrency, through any decentralized wallet and, above all, instantly.

End-to-end encryption of Facebook Messenger and Instagram delayed until 2023
25/11/2021Security and privacy have become two of the main worries of the new virtual world. Meta, the new name of Mark Zuckerberg's company, has been working on end-to-end encryption system for Facebook Messenger and Instagram platforms and has just reported that finally this protection will not be ready until 2023. The delay, they explain, is due to their effort to ensure that end-to-end encryption will be the protection that all their messaging applications have by default, but at the moment only WhatsApp offers it. This technology means that only the sender and the receiver can know the content of a conversation. It's also known that end-to-end encryption has open the debate about privacy and collaboration with police investigations, specially in cases of child abuse. "As we implement end-to-end encryption, we will use a combination of unencrypted data in our applications, account information, and user reports to keep them secure in a way that protects privacy while assisting in public safety efforts" , has assured the Security director of Meta, Antigone Davis.

How to change the IP address?
How to change the IP address? We will explain step by step how to change your IP to be able to browse safely and anonymously on the Internet. The Internet is like a great highway and to "drive" on it, we must get on the road equipped with a computer, tablet, smartphone... with a license plate. This "license plate" is what is known as IP address and for many and several reasons, but mainly for security and/or privacy reasons, we may be interested in changing it. What is my IP? In order not to put the cart before the horse the first thing we must do to know how to change the IP of the computer is to find out what the IP of our connection is and verify that the change has been made correctly at the end of the process. Finding out what your IP is is as simple as visiting Cuál es mi IP (What is my IP). By accessing the page, without the need to download or run any program, our tool will automatically display your IP address data on the screen. This address is also useful to know if you want, for example, to configure online services such as servers, FTP, games, ... and it consists of a numerical combination. This address is unique and public and is the one that identifies us on the Internet to the websites we visit and other users. Nobody can browse the net without an IP address. The IP is assigned to us by our Internet Service Provider (ISP) and as this address is exposed on the network it is known as public IP, as opposed to the private IP of our local network, which only we can know. What is my public IP and what is my private IP? How important are they to change my IP? Our computer or any other device connected to the Internet has two IP addresses, a public IP address, and a private IP address. The public IP, as we have seen, is the one that identifies us to be able to surf the Internet (imagine driving on a highway without a license plate... we would be stopped and banned from driving!) This public IP is linked to our connection and, therefore, all devices connected to the same router have the same public IP. On the other hand, the private IP is the one that individually identifies each device in our private or home network. In this local network, each computer has a private IP address that serves to differentiate it from the rest of the computers and devices connected to the router. In this way, any request for data that comes from or is sent to a device is identified by the router so that it collects or sends the corresponding data to that device. So, which IP address should I change? Private IPs are not accessible from the Internet, while public IPs are and allow us to track our location, data, and Internet activity, including the pages we have visited or the time we have spent on each of them. So, to improve our security and privacy on the Internet, we can change the public IP, or if we prefer, hide our IP. Doing so is not complicated and now we will explain how to change the IP, but first, you must make sure if your IP address is a dynamic IP or a static one, as it depends on it that you can manage to change the IP on your own or require the intervention of your Internet Service Provider (ISP). How do I check if my IP is dynamic or static before changing it? IP addresses can be static or dynamic. In both cases, these addresses are assigned by our Internet provider and the difference between them is that in the case of the static IP, IP addresses can be static or dynamic. In both cases, these addresses are assigned by our Internet provider and the difference between one address and the other is that in the case of the static IP, the address assigned is permanent for a device or router, while the dynamic IP changes every time that device or router connects to the Internet. Usually, the IP address is dynamic, but you can check it through our free tool to find out what is your IP address on our website. Remember that you do not need to download any program or run any application. Simply access cualesmiip.com and the home page will show your IP address, indicating whether it is a static or dynamic one. If it is a static IP address, you will have to contact your Internet Service Provider (ISP) and request the change or use a VPN service as we will explain below. But if it is a dynamic IP address, the change is easy and you have several alternatives for doing so. How do I change my public IP? The easiest way to change the IP address if it is a dynamic one is to turn the router off and on again. This will change the public IP and when you browse again you will do it with a different IP address than the one you had before turning it off. The tricky part of the situation is that the new address, like the previous one, will continue to be exposed on the network and if you want to change it again you will have to turn the router off and on each time. However, it may happen that despite doing so, this does not work and the IP address does not change. This happens because in certain circumstances Internet Service Providers (ISP) establish a certain period before which IP addresses cannot be changed. How to change my IP with a VPN? If you are looking for a solution that does not force you to be aware of turning your router on or off and that also offers a permanent solution that contributes to your online security and privacy, VPNs are already the most effective solution for changing your IP. VPNs are services designed to hide the IP address, whether you connect with a static IP address or a dynamic one, using that of an intermediate server, in such a way that the IP address is masked, appearing to the public as a different IP permanently. As this new Public IP belongs to the VPN server, none of our data is exposed and whoever traces the address will only reach that server, without being able to access any data about our connection, navigation, and identity on the network. VPN vs Proxy Proxy servers act in a similar way, although VPNs have the added advantage that they encrypt all data from the beginning to the end of the communication so that the impossibility of tracing data is 100% guaranteed. Proxy servers do not have this function and therefore your connection may still be susceptible to falling prey to cybercriminals. In addition, most proxy servers, unlike VPNs, must be configured manually and even, in some cases, individually in each browser. How do I know if my IP has been changed? And now that you know how to change the IP, you can test and check whether it went well by comparing your new IP address with the one you had before. If everything went well, you will see that the numbering is different and therefore your IP has been changed.

WiFi Security: Assessment of threats in wireless networks
08/03/2024Wifi connectivity has gone from being limited to restricted environments to becoming omnipresent in virtually every aspect of our daily lives. The ability to connect to the Internet from anywhere, be it at home, in a café, at work, in public spaces, or even in-flight, has enhanced the convenience in our daily lives. Moreover, the expansion of Wifi networks and the use of new manufacturing technologies now allow the interconnection of devices, leading to the significant rise of the Internet of Things (IoT) and providing users with more comprehensive control over their digital environments. However, this proliferation of Wifi networks has also given rise to new threats that require careful evaluation and effective security strategies to ensure secure and risk-free Wifi connections for our data and information. Common Wifi security threats include data interception Man-in-the-Middle (MITM) attacks One of the fundamental challenges in Wifi security is preventing MITM attacks, where an intruder inserts themselves into the communication between two parties, compromising the integrity and confidentiality of sensitive data such as passwords and financial information. Spoofing of access points Hackers can create fake Wifi networks that mimic legitimate ones to attract unsuspecting users. Once connected to these malicious networks, our data can be captured by cybercriminals who may sell or misuse it for illicit purposes. Tips for achieving a secure Wifi connection: Strengthen authentication and use security protocols Prioritize strong encryption for networks to protect confidential information transmitted through it. WPA (Wifi Protected Access) encryption uses stronger algorithms than its predecessor, WEP (Wired Equivalent Privacy), making it more difficult for hackers to intercept and decipher data. Advanced security protocols like WPA3 provide individualized data encryption and advanced two-factor authentication (2FA) methods, adding an extra layer of security by requiring additional verification. Device management Properly manage and monitor devices connected to Wifi networks to minimize risks associated with the large number of connected devices in homes and businesses. Regularly update the router firmware and all connected devices to address potential vulnerabilities. Segmentation of the network to separate critical devices from less secure ones also helps mitigate the risk of threat propagation. Secure Router Configuration The router secure configuration is what will ensure the robustness and overall security of a wireless network. The router, being the first point of contact for devices connected to the Internet, acts as the first line of defence against potential attacks. For this reason, it is important to understand that the proper configuration of the router not only guarantees a stable and efficient connection but also establishes a protected environment that safeguards the integrity and privacy of our data. How to configure the router securely? To ensure a correct and secure configuration of the router, it is recommended to: Change the default username and password of the router, as these are easily accessible to attackers. Use strong passwords containing a combination of letters, numbers, and special characters. Disable remote administration to prevent cybercriminals from accessing the router externally. Enable WPA2 or WPA3 encryption instead of the outdated WEP for enhanced network security. Optionally, disable SSID broadcast to make the network less visible and harder to detect by hackers. Keep the router firmware updated to address vulnerabilities and improve overall device security. By following these steps, you will strengthen the security of your wireless network and reduce the chances of experiencing unwanted attacks or intrusions.

What is Worldcoin and what does scanning the iris involve?
04/03/2024Worldcoin was introduced in summer of 2023 as a revolutionary project with the mission of creating a 100% secure digital identity, essentially a kind of fortified "digital passport," based on the verification of a unique and non-transferable element inherent to each human being—the iris. According to its developers, World ID will help distinguish human online activity from that generated by machines. In the first phase of the project, the creation of this secure digital identity is planned for 2 billion humans. To make this possible, Worldcoin has called on the global population to scan their iris. In return, Worldcoin compensates participants with a few tokens of its successful cryptocurrency, WLD, which has quadrupled in value within a few weeks of its initial launch. The payment in WLD tokens is not coincidental; it is part of Worldcoin's strategy, aiming to leverage the new digital passports to create a comprehensive ecosystem that provides universal and equitable access to advanced financial services for the entire global population. To achieve this, they encourage "iris sellers" to use the Worldcoin cryptocurrency on its fee-free blockchain, unlike Bitcoin, Ethereum, or other cryptocurrencies that do charge transaction fees. How does Worldcoin work? Worldcoin aims to address the issues of bots, rapid creation of fake identities, and content with artificial intelligence. It is designed, according to its developers, to provide every individual in the world with a unique digital identification. Additionally, Worldcoin promises to ensure the financial inclusion of each person in a fair and equitable ecosystem through a universal basic income. Users receive this income in exchange for allowing their iris to be scanned. To create the secure digital passport with Worldcoin, users must undergo an iris scan, which serves as proof of humanity and a unique identity on the blockchain. This process ensures that the individual on the other side of that identity is a human and not a fake profile created with artificial intelligence. In pursuit of the success of their proposal, the company offers users a small amount of their own Worldcoin tokens in exchange for iris scanning. The initial incentive of receiving free cryptocurrency, in the form of a universal basic income, is emphasized by Worldcoin advocates as the basis for the inclusive and universal nature of their initiative. This approach allows anyone to scan their iris, and the WLD tokens received in return can assist people without access to traditional financial services in starting to save and invest. How to Scan the Iris with Worldcoin? The registration process with Worldcoin involves scanning the iris with an orb, the central hardware device of Worldcoin developed by Tools for Humanity. The orb is spherical and processes all the information. Currently, Worldcoin has installed orbs in different countries, including Spain, where users can scan their iris in exchange for Worldcoins. To do this, it is necessary to download the Worldcoin mobile application, World ID, generate a QR code with it, and display it in front of the orb. The orb, upon recognizing it, will scan the user's iris, while a Worldcoin collaborator remotely oversees the operation. The orb takes less than a minute to perform the scan and validate the subject's identity. In exchange for their iris, the user receives a unique number called "IrisHash" and a cryptographic wallet with Worldcoins. "This digital passport is accepted as proof of unique humanity, which people can use in the digital world without the need to share any other data," assure its developers. What happens with my scanned iris in exchange for Worldcoins? Once the iris scan is completed, and digital identity is granted to the user, Worldcoin assures that the orb quickly eliminates the images unless the user requests their preservation. Only the set of numbers called "IrisHash" is stored for identification, without any additional biometric data. Worldcoin also commits to ensuring that users share only the necessary information they wish to share, providing verification options through linked devices or the additional facial authentication orb for high-security cases. Despite these commitments, the collection of biometric data through iris scanning for the unique proof of humanity continues to raise significant questions regarding privacy and information security. Some countries such as Brazil, France, India, or Kenya have halted Worldcoin's iris scanning. How much do you get paid for scanning your iris? Worldcoin pays 25 WLD for scanning your iris, which, according to the cryptocurrency's exchange rate in February 2024, has translated to an average of between 50 and almost €160 for iris sellers, depending on the value of Worldcoin on the day they scanned their iris. At the beginning of February, the value of each WLD unit was around two euros, and by the end of the month, it had risen to nearly seven euros. What can I spend my WLD on? 'Iris sellers' have the freedom to use their Worldcoins from the moment they receive them. They can exchange the payment for other cryptocurrencies, withdraw them in euros from a specialized ATM, or hold onto the tokens in the hope of an increase in their value. Additionally, WLD payments are already accepted on platforms such as Discord, Shopify, Minecraft, Telegram, Mercado Libre, or Reddit, among other places. Who is behind Worldcoin? Worldcoin bears the stamp of two innovative minds: Sam Altman and Alex Blania. Altman is the CEO of OpenAI and a key figure in artificial intelligence development, leading projects like ChatGPT. Blania, on the other hand, is the co-founder of Tools For Humanity, contributing his experience in creating technological tools for a more equitable economic system to this new and successful cryptocurrency.

How can I hide my IP?
Accessing the Internet involves connecting our computer, smartphone, tablet, etc. to a communications server that is responsible for providing access to the network. This connection involves the identification and exchange of data about our identity, IP address, and online activities that are recorded forever as a trace of our navigation. Can I be tracked through my IP address? Yes, it is possible to trace an IP address and for those who consider privacy a priority, this is a major problem because, in addition to being exposed throughout the network, the increasingly intensive use of the Internet has led to this type of data becoming an object of interest for cybercriminals seeking personal or confidential information that can be used for their benefit. To safeguard against all this, there are several methods to hide the IP address, ensure our online privacy, improve our security on the Internet, and prevent anyone from knowing what pages we visit, the time we have spent on every connection, or what we are downloading. What are the advantages of hiding my IP? Apart from everything related to privacy and security already mentioned, hiding the IP offers different advantages for users in multiple circumstances: There are IP hiding services that prevent IP geolocation when we travel and allow us to connect to the network as if we were doing it from our own country, overcoming, for example, any network access limitations that may exist in the place where we are. We will be able to download files anonymously avoiding that the rest of the users can see our IP location. If our IP is not "in sight", the possible limitations and blockages of the Wi-Fi network and even of our ISP (Internet Service Provider) disappear. Thanks to the data encryption system of the most advanced IP hiding services, our vulnerability in connections to public Wi-Fi networks is minimized. When the system detects a location different from the real one, this can give us advantages to buy in online stores with different offers according to the country or to avoid the blocking of games, maps, and online game add-ons that may have restrictions on our location. How can I hide my IP? IP hiding is achieved through the use of specific services and tools to hide the IP and encrypt our traffic, those services allow us to hide the real communications we make during our navigation. Besides those techniques that are based on the modification of network protocols and require certain skills to carry them out, there are several technologies within the reach of all users: VPN or Virtual Private Network Proxy or Web proxy Tor Public Wifi How to hide the IP address with a VPN? VPNs are services that connect us to the Internet through intermediate servers, in which our original IP address is " masked " by the IP address of that secure server. This concealment ensures that anyone tracing our connection will only see the IP address and location of the VPN server, but not our own. In addition, to safeguard our activity on the network, VPNs use tunneling and data encryption, encrypting the information we exchange with the VPN server, hiding it, and preventing third parties from being able to read it during its transit. The security of VPN connections is determined by proprietary VPN protocols, based on different standards and encryption and authentication methods, which depend on each developer. The range of options is wide and this allows us to choose between, for example, options that prioritize speed over security, options that do the opposite, options with a greater or lesser degree of reliability, etc. VPN applications always run in the background and do not hinder browsing. How to use a proxy server to hide the IP address? Unlike VPN services, proxy servers focus their activity solely on hiding the IP, without performing any type of concealment on our network traffic or any other data that could reveal our identity. Proxy servers act as intermediaries between our device and the destination server to which they transmit our requests on our behalf. Therefore, our IP will be hidden and the only one they will see will be the proxy one. There are different types of proxy services, from the simplest ones that only help us to hide the IP to others with extra functionalities such as blocking cookies, scripts, and other files hosted on websites and sent to the user. Browsers or applications based on the HTTP protocol offer the manual proxy configuration function so that we can indicate the proxy web address and port to which we want to connect before browsing. In this way, any activity that we perform through that browser will always be routed to the proxy. Alternatively, you can also opt for the automatic proxy format that searches through DNS or DHCP for the URL from which to download the wpad.dat file that runs and allows the proxy connection with automatic authentication on your computer. How to hide your IP with Tor? Tor is a free software developed to ensure anonymous browsing of users on the Internet. To mask the IP Tor uses a network of volunteer computers or nodes through which it redirects our traffic and encrypts it before it reaches its destination. At least this redirection goes through three of these nodes, achieving repetitive re-encryptions so that any possible clue about our identity disappears. In this process, Tor assigns a random and geographically different IP to our connection so that the location by third parties is impossible (if you are curious to know the IP you have been assigned you can check it through our tool). This system allows different configurations depending on whether we are using a firewall, if our ISP is blocking Tor connections or if we navigate through proxy for example. Can I hide my IP with a public Wi-Fi connection? The answer is yes. A public Wi-Fi network can also be used to hide our IP address, although if we do not have it constantly at our disposal, the IP hiding is limited to the time we have access to a public network. As this type of network is a connection shared by many other people, this makes it impossible to trace a particular user or identify them on the destination server. However, it is precisely this general access that also makes us more vulnerable. And although through a connection to a public Wi-Fi we will solve the issue of IP hiding, security will never be total, because being an open network, we can be exposed to the will of hackers and other threats, including malware and viruses. And if I want to hide my IP address, how can I change it? It may also be the case that instead of masking the IP all we need to do is change our IP address at a given moment. Then, the solution is as simple as disconnecting the modem from the power supply and restarting it after a few minutes. In that time, if your IP address is dynamic (you can check it through the network connections tab on your computer), it will be deleted and your Internet provider will give you a new one. To make sure that everything went well, we recommend doing something as simple as writing down the IP address before turning off the router and checking it again once it is up and running again. Another possible way to achieve the same result if you have a smartphone with a data plan is to turn this device into a wireless access point to which you can connect your computer, thus hiding your usual connection. There are many options to hide the IP or to change it and now that you know how each of them works you will be able to decide which one suits you best.

Proton Mail improves email tracking protecti
02/12/2022Privacy continues to be one of the areas that concentrate most attention and efforts from IT companies and Protron Mail, Proton's end-to-end encrypted mail service, developed by CERN engineers, after learning about mass surveillance of US security agencies, has announced a new level of protection in this regard. Proton will reinforce the protections against the tracking of 'emails' with the aim of offering users a highly privacy service and neutralizing any gap that may have been opened since the creation of this service nearly a decade ago. Proton Mail guarantees their clients, an encryption system that no one except the sender and receiver can access the message. The new version, which will be included by default in iPhone and iPad, also implements new functions that will allow you to schedule the sending of messages, set reminders to answer important emails, and postpone emails that can wait. Proton is also working on the possibility of replying to messages without having to open the text composer and is also finalizing the details of a faster new version for Android

The United States accelerates the digital dollar
23/11/2022After US President Joe Biden ordered this past week to urgently evaluate the creation of the digital dollar, the Federal Reserve Bank and companies such US Bank, Citi, HSBC and Wells Fargo have announced a pilot prove to test the new currency. The digital Dollar will be issued centrally and its regulated liability network (RLN) will be tested for twelve weeks, during which the participating banks will operate in a simulated way, using tokens that will act as deposits from their clients that will be settled in a central reserve in a shared distributed ledger. This will be use to evaluate its security and operation in financial transactions and agreements. In parallel, China continues to promote the Digital Yuan and the European Central Bank (ECB) is also advancing in the creation of the digital euro, a project that the latest information indicates it cab be already viable in 2025. And while all this is happening, the information that ensures an imminent regulation for cryptocurrencies increases.

Until now, the Kremlin has already blocked Instagram, Facebook and Twitter, bringing up the demand for VPNs by Russian citizens to record highs, with the intention of being able to connect to their social networks. VPN connections allows to use internet, preserving the anonymity of the user and his location. The VPN services, connect us to the Internet through intermediate servers, in which our original IP address is "impersonated" by the IP address and location of the VPN server. This makes us appear with a permanently different IP, making it seem that we are in a city or even in a different country than the one we actually are in. VPNs also have the added advantage that encrypts all data from start to finish of the communication, making it 100% guaranteed to be untraceable.

The mining hardware market is booming
09/09/2021There is no doubt about it: cryptocurrency mining is booming. According to a report by Technavio, the mining hardware market is expected to grow by about €2.4 billion between 2020 and 2024. It would grow at an annual rate of more than 7%. So much so that Facebook has already announced that it will launch its own cryptocurrency, a stablecoin pegged to the fiat currency of the country where it operates. It also announced that it will get involved in the NFT industry. Meanwhile, interest in different types of mining tools continues to grow. Day after day, miners join the network. “It began as a niche hobby. Early adopters had to set up rigs on their own and then figure out how to connect them to pools (groups of miners) and earn profit. But since hosting facilities became a thing, anyone can purchase a rig and earn some passive crypto”, explains Josh Metnick, CEO of Navier, a company that hosts different types of miners.

Ransomwhere, new platform to track cyberattack payments
13/07/2021This week was made known the unveiling of Ransomwhere, a new collaborative data platform born with the intention of being able to track 'ransomware' ransom payments to cybercriminals wallets. The platform launched by cybersecurity researcher Jack Cable, allows data to be entered into the Ransomwhere website in an open and transparent format, so that users can easily report on the cryptocurrency wallets used in their ransomware attack payments, often included in the ransom notes of the attacks, and through this data the figure obtained in extortion payments to cybercriminals is obtained. As these payments are made with cryptocurrencies, the transactions can be traced as they are opened by the use of the blockchain or Blockchain. According to the first data obtained in these first weeks of operation, Ransomwhere has reported that it has already recorded more than $33 million paid this past year in ransomware and accumulated data of about $28 million more satisfied previously. This information also shows that the ransomware with the highest income so far is Netwalker, with more than 27 million dollars, followed by REvil / Sodinokibi, with more than 11 million.

Macro cyber-attack affects more than 350 companies worldwide
07/07/2021The number of companies that have suffered from the REvil macro cyberattack now exceeds 350 organizations worldwide from which the cybercriminals are demanding 70 million in bitcoins to provide them with a universal decryptor to restore their data. The attack was conducted through the update system of IT services software company Kaseya, which REvil exploited to spread and hide ransomware. The virus was leaked to TI Kaseya resellers and from there has reached all end customers using their software. The official data provided by TI Kaseya sets the number of affected companies at 350, although other sources such as the cybersecurity company ESET talk about more than 1,000, including some Spanish organizations, although no names have been disclosed. It has been made public that one of the companies most affected by the cyberattack has been the Swedish supermarket chain Coop, which has had to close its more than 800 points of sale for a few days due to the impossibility of using its cash registers or charging customers. Based on Sophos threat intelligence, REvil has been active in recent weeks and is currently the dominant ransomware gang involved in Sophos' defensively managed threat response cases. Prior to this latest attack, they were also responsible for the one suffered by meat company JBS, which forced the cancellation of all work shifts at the company's slaughterhouses in the US. JBS paid up to 11 million to restore normal operations. These macro cyber-attacks are in addition to other recent and highly significant ones, such as the one perpetrated by the hacker group DarkSide, which forced the preventive shutdown of the largest oil pipeline network in the United States, Colonial Pipeline, endangering the supply of fuel in a large part of the country, or the one suffered by the SEPE and the Ministry of Labor in Spain a few weeks ago.

How to keep your Mac safe?
28/06/20215 things you should do to protect your Mac How many times have we heard that Mac is a more than secure and unbreakable system? For years, Apple has made its security through obscurity, or in other words, its proprietary software, flagship and brand guarantee. Today, however, just when Mac is no longer a minority option, Steve Jobs' system has become another favorite target for hackers and cybercriminals. The market has responded to this with the development of specific protection tools for Mac, while Apple works on optimizing its system in each version. Knowing what kind of tools exist for Mac and which ones are already included in our computer will help us to stay safe and choose the best strategy that fits our needs and use of the equipment. 1. Use computer security tools Cybersecurity is a universal and necessary practice in all operating systems today. The objective is to ensure protection against attacks and theft by cybercriminals who are looking for personal or confidential information stored on our computers or that enters or leaves them, in order to use it for their own benefit. What is VPN security? Cybersecurity tools help us to minimize our footprint on the Internet and thus increase our privacy and security. In this regard, VPN services for Mac stand out, as they incorporate advanced protection technologies capable of connecting to the Internet through intermediate servers, so that our IP address - our identification on the network - is replaced by the IP address of this secure server, without anyone being able to trace our connection. This type of VPN service also encrypts any information leaving our computer, thus preventing it from being accessed on its journey to its destination. This is essential, for example, when using public Wi-Fi networks to connect to the Internet. 2. Keep the operating system and software up to date As simple as it may seem, one of the best and easiest ways to protect a Mac is to always have the latest version of the operating system installed and to work with updated software downloaded from the Mac App Store. System updates usually include security patches, among other things. How do I update my Mac? Through the System Preferences Panel of our computer we can set that when there are available updates we receive a notice from MacOs warning us of it or that these updates, whether system data files, security updates or official software are installed automatically. To check if we are working with the latest versions available and our Mac is up to date we can do it by checking through this same panel if there are updates available at that time. If we have checked the automatic updates option, Mac will do this task for us routinely. 3. Use secure settings Mac's default security settings can be greatly enhanced by manually configuring the security and privacy terms of our computer. How to change the Privacy and Security preferences on the Mac? By accessing the "Privacy" tab of the "Security and Privacy" option of the Control Panel we will have the option to manage what information we allow our computer to make available to others over the Internet or on a network and what applications we allow access to our data and files. In the same way, but through the "Security" tab, we will be able to incorporate passwords for the access to different tasks and operations of the computer and through the "FileVault" tool we will be able to ensure the encryption, for example, of our personal information or certain documents for which a password will be required to unblock them. 4. Use an Antivirus for Mac There are antivirus programs developed specifically for Mac. Some of them are special for certain threats, although in general most of them offer a wide range of services to help us keep our computers safe. Which is the best antivirus for Mac? The range of antivirus for Mac, free and paid, is nowadays much wider than a few years ago, highlighting among the most complete and advanced, antivirus with malware protection functions in real time, tools against digital identity theft, protection against spyware or advanced detection and removal of blackmail programs. 5. Make regular backups Apple has a native function, Time Machine, which makes backup copies of our hard disk on a separate secondary disk, so that if for any reason we suffer an attack or a breakdown we can recover all the information. Many antiviruses offer a backup service, backup or backup similar but in the cloud, as a preventive measure against writing errors on the disk, theft of devices or even against data hijacking or ransomware.

How to sign a PDF document with electronic signature?
24/06/2021When a document needs to be signed by one or more people, the usual thing, until now, has been to print it and stamp by hand the necessary signatures to validate or make its content official. This requires paper, printer, ink, but above all access to the document by all signatories, which is not always easy due to geographical location, availability, timing, etc. With teleworking on the rise and a growing globalization of business, these drawbacks have become more evident than ever, although they have found a quick and effective solution in electronic signatures. What is an electronic signature for? The electronic signature is a digital validation system for documents that unequivocally identifies the signatory. The electronic signature is assimilated to the handwritten signature and therefore its digital stamping on a document gives it the same validity, as it would have had with a handwritten signature. What are the advantages of electronic signatures? Electronic signatures simplify document management processes that require the validation of documents such as pdf signatures, facilitating remote signing by one or more people regardless of where they are located, or the situation or time of day they receive them. This flexibility contributes to the efficiency and agility of this type of procedure and being a secure signature system, it is suitable and useful in many areas related to business management, administrative management, e-commerce, informed consent and many other procedures. In addition to the versatility, practicality and security of the online PDF signature, we must also point out, as a great advantage of this process, its contribution to paperless. How to sign electronically? The electronic signature is easy to implement through tools specifically designed to guarantee not only the correct validation of the cryptographic signature or signatures included in a PDF document, but also that it cannot be altered and that all the necessary signatures required by each situation can be added. Within the framework of this type of tool, the most advanced ones, in addition to being compatible with any browser and accessible from any type of device - computer, tablet, Smartphone,... -, make it easy to convert PDF any Word, Excel, JPG, PowerPoint... file for signing. They also allow users to request a verifiable digital signature, view the properties of the digital signature and send the document directly by email to the signatories and once signed, forward it to all parties to download it. In addition, to guarantee the privacy of the documents and the security of the online signatures, these transfers are made through encrypted files with TLS encryption. Also, when we sign documents using this type of tool, they offer the option of including a LTV (Long Term Validation) time stamp that certifies the validity of the signature in the long term. For all these reasons, tools for signing PDF documents with electronic signatures are now a must for companies and businesses in all areas where process optimization, security and sustainability are a priority.

What is the value of a Bitcoin?
11/06/2021Since Bitcoin first appeared in 2009, this digital currency not issued by any government or company, nor, under the umbrella of any kind of economic policy, has gained a foothold in the market and has already started to fit into existing legal frameworks. What gives Bitcoin its value? The great value of Bitcoin is that it is a decentralized and global currency, an alternative to fiat currencies (those issued by governments). All transactions with Bitcoins are public and each of these crypto currencies belongs exclusively to its owner, therefore, it is a currency that cannot be intervened by anyone. What can I do with Bitcoins? To date, with this cryptocurrency, it is possible to monetize all kinds of services, in addition to making investments, free or practically free of commissions, which in the medium to long term are proving attractive. This has made Bitcoin an asset in which to invest and an increasingly popular means of payment through which to transfer value from one user to another without losing friction along the way, going through an intermediary or paying a commission. What is the price of a Bitcoin? Like any other good, the price of a Bitcoin varies according to market demand, although the fact that it has been designed to behave as a deflationary asset and that its supply is limited to 21 million coins, facilitates that by the law of supply and demand itself, the Bitcoin exchange rate tends to rise continuously. As of June 9, at the time of writing this article, the Bitcoin value today is 30,007.86 euros, 3.4 times its price a year ago, when the Bitcoin to Euro conversion rate was 8,629.5 Bitcoins for 1 euro. In 2010 Bitcoin price was less than one Euro cent. What does the value of Bitcoin depend on? The value of Bitcoin depends on the trust and acceptance of users to use it, hence why Bitcoin is rising in value some days and not others. As Bitcoin has been implemented as a means of payment in multiple transactions and its popularity has grown, its value has grown in parallel. Likewise, when there have been news or events that have questioned, for example, the suitability of this crypto currency, its price has fallen. Like any other currency, the price of Bitcoin fluctuates and it is the users themselves who set it at the time of the purchase and sale transaction, which prevents the existence of a single price for Bitcoin, since it is not operated through a single platform as is the case with other currencies. Even so, buying and selling prices of Bitcoins tend to be quite similar. To know how much Bitcoin costs, there are several online platforms, known as "Bitcoin trading platforms" that report live the evolution of the value of the cryptocurrency. Is it safe and profitable to invest in Bitcoin? As with any other asset, investing in Bitcoins is profitable if we know how to do it at the right time. On the other hand, the Blockchain technology on which Bitcoin is based is reliable and difficult to manipulate, with no risk of being counterfeited, although some experts believe that the perfect, 100% inviolable system has not yet been created. In the cryptocurrency segment, convertibility is contemplated, so that Bitcoins can be exchanged for fiat currencies. What can I buy with Bitcoins? Over the last few years, a large number of companies have incorporated Bitcoin as an official method of payment for their goods and services From travel companies to ticket sales platforms for all kinds of shows, through gaming platforms, digital bookstores, software stores or even non-profit organizations already accept this digital currency. That is, Destinia, 13tickets, Gear Best, Shopify, Wordpress, Hostinger, Greenpeace,... among many other companies. eBay is currently considering adding Bitcoin as a method of payment. What is Bitcoin mining and how are Bitcoins generated? The users themselves through a totally decentralized system create Bitcoins. To become a bitcoin creator, computers with high computational capacity are needed to process and verify transactions and quickly solve the complex digital processes of generating the currency. This work is called mining and one of its best attractions is that the system offers "miners" rewards in Bitcoins in exchange for these services, which has made this activity very appealing for certain users. Is it profitable to mine Bitcoins in Spain? Bitcoin mining requires very powerful equipment, with high calculation capacities to solve operations, being nowadays totally inoperative for this operation the PCs of domestic or office use. The investment to mine Bitcoins requires, in addition, to assume the large power consumption required by this more powerful equipment, which makes Spain, at this time due to the high price of KW/h, an uninteresting market for mining Bitcoins. On the contrary, other locations such as China, Iceland, Iran or Georgia, where the Bitcoin mining business is in full expansion, are very interesting.
