Computer Attack Mimics ser's Keystrokes, Evades Detection
Researchers at Ben Gurion University in Israel have identified a new form of computer attack that uses a compromised USB keyboard to generate keystrokes that mimic an attacked user's typing.

Researchers at the Malware Laboratory of Ben-Gurion University of the Negev (BGU) in Israel have identified a malware technique designed to evade detection via individualized keystroke characteristics.
The Malboard hack involves compromising a Universal Serial Bus keyboard to automatically produce and transmit malicious keystrokes that emulate a targeted user's typing style.
BGU's Nir Nissim said tests showed Malboard successfully evaded three existing detection mechanisms, in 83% to 100% of cases.
The researchers also developed modules to detect such attacks, which BGU's Nitzan Farhi said were "capable of detecting the Malboard attack in 100% of the cases, with no false positives. Using them together as an ensemble detection framework will ensure that an organization is immune to the Malboard attack, as well as other keystroke attacks.”
