New Bluetooth Crack

By on June 3, 2005

Happy Friday:

Cryptographers have discovered a way to hack Bluetooth-enabled devices even when security features are switched on. The discovery may make it even easier for hackers to eavesdrop on conversations and charge their own calls to someone else’s cellphone.

“Our attack makes it possible to crack every communication between two Bluetooth devices, and not only if it is the first communication between those devices,” says Shaked.

Check out the time required to pull this off:

They show that once an attacker has forced two devices to pair, they can work out the link key in just 0.06 seconds on a Pentium IV-enabled computer, and 0.3 seconds on a Pentium-III. “This is not just a theoretical break, it’s practical,” says Schneier.
