Quote:Dozens of HP laptop models have been found to contain an audio driver that silently logs users keystrokes, according to Swiss security firm ModZero. There does not appear to be malicious intent behind the keylogger, as one might automatically assume, but there is the potential that it could be used for nefarious purposes.

Injecting a keylogger into an audio driver seems like an odd thing, and that's because it is. However, audio chip manufacturer Conexant apparently went that route on several HP laptop models as means of trying to detect when a hotkey is pressed. Shortcuts exist for tasks such as turning a microphone on and off, and that presents a problem.
