Surely you have ever heard that phrase that “there are no viruses or threats on Mac”, that little less than those phenomena associated with computer security are the exclusive practice of Windows 10 and PCs. Well, although in the number there are differences between one and the other, we have the bad news to give you that the Apple ecosystem is not spared either from the odd little problem. And proof of this is the alert launched by Apple a few hours ago, when it decided to update Bug Sur to version 11.4 to close, precisely, one of the latest threats detected in its operating system, one that takes advantage of a so-called zero-day error and that has been present on the platform practically since its inception. Update to the latest version now. Thus, those from Cupertino have launched an update for Big Sur that is responsible for correcting some errors in Safari and offering expanded support for external GPUs (graphics cards), among other things, although the one that most should matter is the final closure of the security hole used by this new malware discovered and that was responsible for taking screenshots outside of our control It has been the company Jamf that has raised the alarm when finding evidence that the XCSSET malware was acting through an exploit discovered in Apple’s OS, which allowed it to obtain screenshots of the user. That means, not only knowing what we are doing, but also monitoring all our activity in search of relevant information and data. For example the banking, who are always the sweet tooth. In any case, the threat did not come only because of its potential to access the disk and record the screenshots, but it also left the door open for a larger-scale attack that, yes, could cause greater damage to the computer. The entire process also went unnoticed by the user, who was practically at no time aware that his computer had been invaded by this XCSSET. To avoid having problems with this threat in the future, you just have to go to the apple menu in the upper left part of the screen and in “About this Mac”, click on the option “Software update” that you will see in the first tab of “Overview”. From there you can download Big Sur update 11.4.
