Researchers Use New CPU Attack to Steal Linux Root Password Hash From Memory

Branch Target Reuse (BTR) is a newly disclosed variant of the Spectre-v2 attack that leverages stale CPU branch-prediction data to leak sensitive information from Linux memory, including root password hashes. This attack specifically targets just-in-time (JIT) compilers found in the Linux kernel, web browsers, and various language runtimes. BTR...
