A newly discovered security flaw in Intel processors allows attackers to steal any data that’s been recently accessed by the processor. That even holds true on cloud servers, which could allow an attacker to steal information from other virtual machines running on the same PC.
It’s not known whether the attack, dubbed ZombieLoad, has been used by malicious hackers. The flaw was discovered by researchers from Graz University of Technology and was disclosed to Intel. Intel has issued code to patch the flaw, though it has to be implemented by individual manufacturers and then installed by users before everyone is protected.
