There is mysterious ‘undocumented technology’ hidden on
Intel computer chips, researchers say

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, even
though the research does not prove long-standing rumours that the NSA has
hidden ‘back doors’ on computer chips which are used to spy on billions of
people.
Maxim Goryachy and Mark Ermolov revealed their findings
at the Black Hat Conference, a gathering of hackers and cybersecurity
specialists in Singapore.
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.
This ability would be useful to hackers looking to steal
information – as well as spies or anyone else interested in stealing sensitive
information.
Normally, VISA is turned off in commercial systems. Yet
the researchers claimed to have found a way to switch it on.
‘We found out that it is possible to access Intel VISA on
ordinary motherboards, with no specific equipment needed,’ said Positive
Technologies expert Maxim Goryachy.
Intel told Metro that the VISA vulnerability was real,
but said it ‘required physical access’ meaning that hackers couldn’t activate
it over the internet and begin stealing information.
However, it said the flaw had been addressed and solved.
‘The Intel VISA issue, as discussed at BlackHat Asia,
relies on physical access and a previously mitigated vulnerability,’ Intel told
us.
‘Customers who have applied those mitigations are
protected from known vectors.’
