Computer experts have claimed that the chips which power most of the computers in the world are hiding mysterious and ‘undocumented’ technology. Analysts from Positive Technologies alleged that Intel chips and processors contain an enigmatic ‘logic signal analyser’ capable of reading ‘almost all data on a computer’. The claims are likely to alarm conspiracy theorists...

The analyser was discovered in the Platform Controller Hub (PCH) on Intel motherboards as well as the main processor itself. Together, these parts of the computer serve as its ‘brain’. It’s called VISA and can potentially allow hackers or spies to access the information stored in the computer memory as well as the information generated by ‘peripherals’ – the name for computer accessories which could include anything from a webcam to a mouse. The VISA technology was believed to be used to check Intel microchips for flaws, but Positive Technologies suggested it could also be used to ‘capture and analyse’ data.
