Intel continues to have a Plundervolt security vulnerability that reduces CPU voltage

Recently, a cyber security research group announced a security vulnerability affecting Intel microprocessors. The flaw was first discovered by the team in June 2019 and notified Intel.

The hole, called 'Plundervolt', is a combination of the words 'plunder' and 'undervolt'. Plundervolt disables security when it performs encrypted computing tasks by reducing the voltage (undervolt) supplied to the processor.

Unlike previous security holes, Plundervolt will change bits of data right from within the processor before they are written to memory.

According to the researchers, this vulnerability is extremely dangerous because hackers can use it to perform this attack remotely.

After receiving the vulnerability report, Intel worked with motherboard and OEM manufacturers to remedy this situation. A BIOS update with a new microcode will be released soon.

In January 2018, Intel also faced two security holes, Specter and Meltdown at the same time. The fix patch then caused the CPU performance to drop, causing Intel to turn it off and work with Microsoft to release another emergency patch.
