#Plundervolt : A new attack on #Intel processors threatening SGX data

Simply put; Plundervolt flaw lets attackers manipulate voltage delivered to targeted CPU and steal data. 

Altering Intel’s CPU voltages and frequency directly in the operating system is a feature that many users appreciate as it allows them to use all those software-based utilities that aid in overclocking. Now, this feature may not be as secure as previously anticipated.

New Plundervolt attack impacts Intel CPUs

Intel desktop, server, and mobile CPUs are impacted. Intel has released firmware patches today.

[...]
According to Intel, the following CPU series are vulnerable to Plundervolt attacks:

Intel® 6th, 7th, 8 th, 9th & 10th generation CoreTM processors

Intel® Xeon® Processor E3 v5 & v6

Intel® Xeon® Processor E-2100 & E-2200 families

Plundervolt is nothing that end-users should worry about. It's an attack vector that is of little interest for malware authors since it's hard to automate at scale. It is, however, an attack vector that could be weaponized in targeted attacks, against specially selected targets. If Plundervolt is a serious threat depends on each user's threat matrix.
