Computer Warming a Privacy Risk.
By Quinn Norton.
BERLIN -- A security researcher has a devised a novel attack on online
anonymity systems in which he literally takes a computer's temperature
over the internet.
The attack uses a phenomenon called "clock skew" -- the tendency for the
precise clocks in modern computers to drift off of the correct time at
slightly different rates, which can be affected by heat.
"When a crystal is manufactured, it has a clock skew, and it's different
for each crystal (throughout its) lifetime," explains Steven J. Murdoch,
a Cambridge University researcher who discussed his work at the Chaos
Communications Congress on Thursday.
