'Google today disclosed a security bug in its Bluetooth Titan Security Key that could allow an attacker in close physical proximity to circumvent the security the key is supposed to provide. From a report:

The company says that the bug is due to a "misconfiguration in the Titan Security Keys' Bluetooth pairing protocols" and that even the faulty keys still protect against phishing attacks. Still, the company is providing a free replacement key to all existing users. The bug affects all Titan Bluetooth keys, which sell for $50 in a package that also includes a standard USB/NFC key, that have a "T1" or "T2" on the back.'

Rather than "Titan", they should have called it "Achilles"... ;-)
