Meta test end-to-end encryption on calls and messages in their virtual reality glasses
30/05/2022Meta announced some time ago their desire to improve the privacy of their users and the confidentiality of their conversations, and in accordance with this, the company has just presented a new software update, v40, for its Meta Quest 2 virtual reality glasses, which tests the encryption of end-to-end of both calls and Messenger conversations that can be done through this device. In addition, this update incorporates a new function in App Unlock, which allows the user to block certain games and 'apps' with a security pattern plan. Another new feature is the secure payment system in 3D Secure, which is presented as an alternative to the Oculus app. The Meta Quest 2 glasses also receive with this update the possibility of being paired with other keyboards through Bluetooth connectivity, being fully compatible with Apple keyboards. Finally, among the outstanding novelties of this new v40 update, is the possibility of hearing the same thing from the speakers on the left and right of the viewfinder and even from the headphone jack. In addition, there is the option to adjust the left and right audio channels for those who hear better from one side than the other.

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.

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.
