Yesterday, Swiss cybersecurity company modzero AG reported that they had discovered a keylogger from a laptop produced by Hewlett-Packard. The keylogger was found from an audio driver package digitally signed by the audio chip manufacturer Conexant. HP reacted immediately and released a fix for the issue in the form of a driver update, available both in Windows Update as well as at The reason for the error was that the feature mistakenly made it into production code.

According to the findings, the keylogger captured all of the user’s keystrokes and saved them to a local log file in plain text. More technical details and a list of affected hardware product models are listed in modzero’s Security Advisory.


What should I do?


It is recommended that you update your systems with the HP-issued updated driver version immediately. The update will also remove any remaining log files from your computers.

You can find possibly affected systems by checking whether they contain the file C:\Windows\System32\MicTray.exe or MicTray64.exe.
