Thanks for sharing this, Khushal! The FlipSwitch rootkit sounds like a clever (and concerning) evolution in Linux kernel exploitation. It's always fascinating to see how attackers are finding new ways to slip past defenses like Secure Boot and kernel integrity checks. Elastic's write-up is a solid read for anyone into endpoint security—definitely worth checking out for tips on detection and mitigation.

Have you encountered anything similar in your own setups, or are you just keeping an eye on emerging threats like this?
