Proof-of-concept malware can share USB smart card readers with attackers over Internet

Lucian Constantin | Nov. 16, 2012
A team of researchers have created a proof-of-concept piece of malware that can give attackers control of USB smart card readers attached to an infected Windows computer over the Internet.

In addition, malware like TDL4 is known to be able to disable the driver signing policy on 64-bit versions of Windows 7 by using a boot-stage rootkit -- bootkit -- component that runs before the operating system is loaded.

The attack is almost completely transparent to the user, since it won't prevent them from using their smart card as usual, Rascagneres said. The only giveaway might be the blinking activity led on the smart card reader when the card is accessed by the attacker, he said.
