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.

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.

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.

Ip Location, the tool to know my ip location
If you need to check what location your internet provider is sharing with the websites you visit, with our IP locator you can instantly geolocate your IP address or any other that you enter manually. To geographically locate the IP address, you only need to be connected to the internet. If you use VPN software or connect through a proxy to locate IP address you can also use our tool. None of the data generated by the IP locator is stored in our system. @Mapa@ How can I hide my IP address so that it cannot be traced? To anonymously browse the Internet and avoid being located through the IP of your connection, there are two basic ways to do it. The first is to hide IP so that no one will be able to track our presence on the network or access our browsing data and the second is to change IP and browse through another IP address whenever we need to. Why do I need to locate my IP geographically? Locating your IP geographically is the best way to find out what data our ISP shares about the location of our connection. Depending on this location. a website whose URL is ".com" will change to "/es" if we connect from Spain, for example, and some tasks related to the sending of forms will be simplified, as they will be automatically pre-filled with some data such as your country or city, depending on your geolocation IP. As users with a geolocation IP tool such as the one we offer in Cuál es mi IP, we can manually enter an IP address and find out, for example, from where we have received a fraudulent email, if we have had access before, of course, to the IP address involved Can anyone find out my home address with an IP geolocation tool? By using a tool to locate an IP address, you can trace the IP and geolocate it through coordinates on the map, but the specific postal address is never provided. This is because our IP address is not ours, but rather our Internet Service Provider's (ISP's). So what data can they find out about me with IP geolocation? When locating the IP geographically. the only information about us that is provided is the country and city from which we are connecting, since the GPS coordinates of altitude and latitude that are shown correspond, in reality, to those of the headquarters of the company that is offering us the Internet connection service. The reason behind this is that all data related to the actual geographic address of the device used to access the Internet, i.e. our router, is not public and belongs to our ISP, which can only disclose it by court order. Why are companies interested in locating my IP address geographically? Information is power and for a company to know from where its potential customers connect is an important advantage to design marketing strategies aimed at the customer profile of a particular geographical area or country. In addition, in terms of anti-fraud, e-commerce companies can improve card payment security by identifying payment attempts from suspicious IP addresses. What is an IP address? An IP address is a special numerical combination assigned to an internet-connected device to be identified on the network. All intelligent devices need an IP address to access the Internet and interact on the network. Each device connected to the Internet has its own an individual IP address. When we access the Internet, the servers recognize our device through its IP address, allowing the two-way communication with the recipient. As we are identified with our IP address, the rest of devices can order a return response, without mistake the sender. Making a simile, an IP address would be the address that we use to write on the back of an envelope. This information identifies us as issuers and also as recipients of the return answer. To make possible this data exchange, the IP protocol was established as a set of universal rules for all the Internet operations. That means that all devices connected to Internet or to a home network, "speak" the same language and they are able to communicate each with the others. There are two types of IP address, the external IP and the local IP: • The external IP or public IP is the numerical combination address assigned to us by our Internet service provider (ISP). This public IP identifies us as Internet users when we are connected. If you want to find the IP of your computer, your tablet or your Smartphone, you can find out this immediately by accessing the home page of “What is my IP” or using our speed test service that, in addition to this information, will inform you about the quality of your Internet connection. • The local IP address or internal IP is the one the router assign to all the devices connected to him and identifies each of these devices, individually, in the home network. How to locate an IP address? If you want to know how to find out where an IP address is from, you should know that it is not always easy to find out the IP origin of a connection, because there are different systems to hide the IP. Some users use these systems for security reasons or to simulate, for example, their IP location in another place and thus have access to Internet services not enabled in the place where they are located. Now, if the user does not use any resource to mask the IP, find out the IP of the computer or any other device connected, for example, to our website, it is as simple as use IP geolocation services such the one offered in “What is my IP?” and you will immediately find out the IP origin of any computer that you are interested in track. Knowing the IP location of our clients is an advantage when we are designing, for example, our marketing strategies and a good tool, also, to improve network security, as it allows us to locate suspicious IP addresses. In addition, with the IP geolocation service you can also verify the location that your Internet provider shares about you. It should be clarified that this location provided by IP geolocation services is never the specific address of our home or where we are located. The data actually are from the operator node in our area that is offering us the connection service to the internet network Therefore, the geolocation information will be the country and city from where the connection is made, but not the address where the user is located, because this specific tracking of the user address is protected by law and this data can only be provided by court order.

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.
