New Intel Chipset “Feature” Could Compromise Data

Most of us remember the Spectre and Meltdown bugs of early 2018. This led to Microsoft pushing an emergency patch and Apple making a nebulous statement among other things. Intel released their first CPUs that were not vulnerable late last year. However, it looks like a new undocumented Intel chipset feature is wreaking havoc once again.

Intel’s Visualization of Internal Signals Architecture (VISA) technology is designed to help with testing and debugging during the manufacturing process. It intercepts electronic signals from peripherals and busses and, if compromised, could reveal all kinds of data. Luckily, VISA is not active or available to users. However, two researchers found away to enable it and sniff data going through the CPU. All modern Intel chipsets use VISA.
