SWAPGS Attack
SWAPGS attack is a type of security vulnerability that affects the way computers use a process called speculative execution to speed up their performance. Essentially, it allows malicious software to access kernel memory on a computer, which could potentially give attackers access to sensitive data.
When your computer executes a process, it often runs multiple tasks at the same time in order to make things go faster. This is called speculative execution. The problem is that sometimes, this process creates a security vulnerability that hackers can exploit.
The SWAPGS attack specifically targets a particular type of CPU instruction called SWAPGS, which stands for “swap global storage”. In certain scenarios, hackers can use this instruction to gain access to kernel memory on a computer, potentially giving them access to sensitive data like passwords or financial information.
So essentially, the SWAPGS attack is a way for hackers to exploit a vulnerability in the way computer processors work, in order to gain access to confidential information. It’s important for computer users to stay aware of this type of vulnerability and take steps to protect themselves against potential attacks.
