Hackers could steal your data via an unpatched GPU pixel-stealing attack. Though that ‘could’ is doing some real heavy lifting | #hacking | #cybersecurity | #infosec | #comptia | #pentest | #hacker

A potentially scary, though difficult to implement side-channel attack that could allow malicious websites to read and extract sensitive data has broken cover. The vulnerability affects all GPU manufacturers across devices ranging from PCs, to laptops and phones.

According to a paper released by researchers from four American universities (via Ars Technica), the so-called attack relates to GPU compression data. This is proprietary so it would require a hacker to have a deep knowledge of GPU compression algorithms, which are closed in nature and would require reverse engineering. That’s no mean feat for a start.
