At the Black Hat Asia 2019 security conference, security researchers from
Positive Technologies disclosed the existence of a previously unknown and
undocumented feature in Intel chipsets. From a report: Called Intel
Visualization of Internal Signals Architecture (Intel VISA), Positive
Technologies researchers Maxim Goryachy and Mark Ermolov said this is a new
utility included in modern Intel chipsets to help with testing and debugging on
manufacturing lines. VISA is included with Platform Controller Hub (PCH)
chipsets part of modern Intel CPUs and works like a full-fledged logic signal
analyzer. According to the two researchers, VISA intercepts electronic signals
sent from internal buses and peripherals (display, keyboard, and webcam) to the
PCH -- and later the main CPU. Unauthorized access to the VISA feature would
allow a threat actor to intercept data from the computer memory and create
spyware that works at the lowest possible level. But despite its extremely
intrusive nature, very little is known about this new technology.
