USB devices can be used by hackers: researcher

[BOSTON] USB devices such as keyboards, thumb-drives and mice can be used to hack into personal computers in a potential new class of attacks that evade all known security protections, a top computer researcher has revealed.

Karsten Nohl, chief scientist with Berlin's SR Labs, noted that hackers could load malicious software onto tiny, low-cost computer chips that control functions of USB devices but which have no built-in shields against tampering with their code.

"You cannot tell where the virus came from. It is almost like a magic trick," said Mr Nohl, whose research firm is known for uncovering major flaws in mobile phone technology.
