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.

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.

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.

How to know if Pegasus has infected our mobile
05/05/2022The news of recent weeks, in which it is claimed that the Pegasus espionage program has been used to enter the mobile devices of Spanish politicians, has put a lot of people on alert. Pegasus is a malicious software that, once introduced on a device, has the ability to collect information and transmit it to an external entity without the consent or knowledge of the owner of the device, be it a mobile phone, a computer or a tablet. Pegasus also erases its trail after it is installed. Among its main features, it also stands out that Pegasus is capable of detecting who the owner of the device has been with. Pegasus also, can send and recive messages autonomously and recording conversations by manipulating the attacked mobile, computer or tablet. The two ways that this spy program uses to enter on a devices is through an SMS or a fraudulent link and, according to experts, despite the fact that it is a very difficult spyware to detect, there are some signs that can make us suspect that we have been infected. Overheating or slowdown of the system are two of the main ones, but also the fact that the battery life is decreasing or that there is excessive data consumption when we are not using the device. How to make it difficult for Pegasus To try to avoid being infected by Pegaus or by any other malware, the director of Systems Engineering at Fortinet from Spain and Portugal, José Luis Laguna, in statements collected by Europa Press, recommends taking extreme precautions and a make a double-checking when personal and confidential information is provided. In addition, the Fortinet expert explains that instead of clicking on the link that we have received, to verify that it is legitimate, it is recommended to write the address of the site in the web browser, even though this means taking an additional step and not accessing directly to this service. Using protection 'software' based on behavior - EndPoint Detection and Response (EDR) -, keeping the system updated, avoiding public Wi-Fi connections and checking the permissions granted to applications, are other precautions that are also recommended.

What is web hosting and why do you need it?
09/09/2021If you are thinking of creating your own website or if, on the contrary, you already have one and are looking for a better web hosting service, you probably have many doubts concerning web hosting: what exactly is it, what are its different types, why do I need it, etc. For this reason, here we offer you a clear and simple guide to web hosting. What is web hosting? Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet so that it can be consulted at any time and from any place and device. The content of the websites is stored, therefore, in web servers. These servers allow the content to be accessible via the World Wide Web. For all those who do not know the term, a web server is a piece of computer equipment that is much more powerful than any conventional computer and that is connected to the Internet 24 hours a day to enable access to the contents it stores. Different types of web hosting are offered based on the web server: shared hosting, VPS, cloud hosting, WordPress hosting, elastic hosting, etc. These services are offered by web hosts such as Webempresa, which provide space on a server for use by clients. Why do you need web hosting? Web hosting allows your website to be always online and available worldwide and for everyone. Therefore, even if you can afford to buy your own server and have a fast internet connection, it is advisable to hire a web hosting service, as it will be much cheaper. Web hosts have their own servers to host their clients' websites. These servers are located in a Data Processing Center (DPC): an infrastructure that has the most advanced security systems and stable and secure internet connections, which prevent errors in the services. What are the different types of web hosting? Although there are different types of web hosting in the market, the most common are the following: shared hosting, dedicated hosting, VPS (Virtual Private Server) hosting, cloud hosting, reseller hosting, and WordPress hosting. Each of them meets the needs of a particular group of customers. Shared hosting is the most basic type of web hosting. The provider rents small spaces on a single server to different websites. In this way, all customers have their own space to host their content, while sharing server resources such as CPU, processor, RAM, bandwidth, or IP address. In contrast, a dedicated hosting service is a type of web hosting in which the client leases an entire server and does not share it with anyone else. Although shared hosting works very well, a dedicated server stands out because it is never affected by existing traffic and because it has a higher level of security. A virtual private server (VPS) is basically a server running within a server. One physical server hosts multiple virtual servers, each isolated from the others. Each VPS runs its own operating system, independent of the others. The features offered by a virtual private server are very similar to those of shared hosting. At the same time, it offers all the benefits of a dedicated server. Cloud hosting works in a very similar way to the "cloud" where we store all kinds of documents. This is because all the resources that are used to collect the information of a website are executed from a cloud server. The main difference between cloud hosting and other web hosting types is that, in this case, you only pay for the services you use. Reseller hosting is another type of web hosting. It is basically white-label web hosting. A person buys hosting from a provider and then resells those services to his/her clients. This allows the creation of hosting plans and external domains or subdomains. The last type of web hosting we will talk about here is email hosting, which allows you to register a domain name and therefore have a professional email service. This type of web hosting is highly recommended for businesses or individuals that intend to convey an image of seriousness and trust. Thus, thanks to email hosting, you will be able to have a personalized email address, more storage space, and a higher level of security.
