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.

Meta warns about the vulnerability in password recovery linked to the recycling of phone numbers
22/02/2024Meta, a leader in social media, has announced that it will not assume responsibility for personal account theft on Instagram and Facebook related to password recovery through the use of recycled phone numbers. The company argues that it lacks control over telecommunications providers and users involved in this practice. Phone number recycling: an overlooked risk in a recent statement Meta revealed its inability to manage personal account thefts that occur when phone numbers are recycled by telecommunications carriers. This common practice among mobile phone companies involves reassigning discarded numbers to new customers, making them owners of a number previously used by another user. In countries like Spain, carriers wait for a period of 30 days before reassigning a number, but the risk persists if users do not unlink the number from digital services or associated platforms, such as social networks and emails. The danger of not unlinking phone numbers from digital accounts When users deactivate a phone number, whether due to a change of carrier or any other reason, carriers must wait before reassigning the number. However, failure to unlink this number from digital services can result in unauthorized access to personal accounts. In many services, linking the phone number is allowed for actions such as resetting passwords. Users, upon receiving a verification code on their number, can complete the login without the need for email validation or a password. This process, though accepted, can lead to unintentional unauthorized access. Meta warns users about the importance of unlinking phone numbers from digital accounts when deactivating them, insisting on the need to update associated information to prevent account theft.
