Intel CPUs Face Spectre-Like Attack That Leaks Data | Darkreading

Researchers at the University of California San Diego (UCSD) have found a new way to execute Spectre-like side channel attacks against high-end Intel CPUs, including the recent Raptor Lake and Alder Lake microprocessors.

Like Spectre, the new technique, which the researchers have dubbed "Indirector," exploits a speculative execution feature in the Intel CPUs to redirect the control flow of a program — that is, the order in which it executes individual instructions and function calls.

Spectre-Like Side Channel Attack
An attacker could use the tactic to essentially trick the CPU into making incorrect speculative executions and leak sensitive data.
