Keylogger Discovered in HP Audio Driver

Tom LiMay 12, 2017

A keylogging vulnerability has been discovered in HP laptop’s audio driver, says the independent Swiss security firm Modzero.

The security concern stems from the way the audio driver handles inputs from media control keys. The driver process, called MicTray64.exe, records when media keys are pressed and change settings accordingly.

This is harmless on its own, but the problem is that the driver also writes keystrokes to a text file called MicTray.log. If the file is obtained, the attacker can extract personal information such as passwords and credit card numbers.

The situation is made worse when the MicTray.log is not created or doesn’t exist. In that case, all keystrokes are passed off to the OutputDebugString API, which allows any process in the Current User context to obtain keystrokes real-time without being detected by the antivirus.

Affected models include:

  • HP EliteBook 820 G3 Notebook PC HP EliteBook 828 G3 Notebook PC
