VISA: The Undocumented Security Problem Inside Intel — What You Need To Know

Researchers have revealed a previously undocumented technology hiding inside Intel chips that could potentially leave the door open to attackers…

During a presentation at Black Hat Asia in Singapore yesterday, two security researchers from Positive Technologies revealed how an undocumented technology inside Intel microchips might be activated by attackers. The Visualization of Internal Signals Architecture (VISA) enables data from memory to be read, and signals from peripherals to be interrupted. Its purpose appears to be that of detecting flaws in processors and microchips, but the researchers think it could be used for nefarious purposes by threat actors.
