| Your graphics card exposes your computer to hackers |
The PC primarily depends on the graphics card to perform a variety of tasks. Because in addition to its primary role in artwork such as image design or video editing, it is also used to play and edit game content.
Hackers have found a way to perform these attacks using only the graphics card. This is done by searching the card's RAM module with a specific code, which, in turn, transmits it to the system.
The creator of this method has been shown to work with embedded Intel cards as well as NVIDIA and AMD external cards. The idea behind this method is very clever. This is because antivirus and malware apps can't scan your graphics card's RAM, so hackers resort to mining.
This method was first posted on the hackers forum. Then the method editor provided evidence that his method was working correctly. Tested on different types of graphics cards such as Intel UHD 620, AMD Radeon RX 5700 and GeForce GTX 1650.
The method was announced on August 8, and on August 25, the owner of the method announced that he had successfully sold it to a forum goer, but did not reveal the sale process or details of how the method worked.
Graphics Card Hacks
While the exact details of how this method works are unclear, security researchers say it relies on the graphics card's implementation of the code and its RAM, rather than the main CPU and RAM.
A similar method called JellyFish appeared a few years ago, and was allowed to integrate an application that also logged everything that was written as a keylogger on the graphics card.
However, the developer of this method explained on the forum that there is no similarity between the JellyFish method and their method.
So far, there is no complete information about this new threat. Since it is not widespread, it is still unclear how to prevent it. However, it is always recommended not to download files from untrusted websites or platforms. Also, only open email attachments from trusted senders.
