A Swiss specialist has found a keylogger in an audio driver on numerous Windows portable PCs made by HP Inc.

The specialist, Thorsten Schroeder, said the reason for the keylogger was to perceive whether a unique key had been pressed or released.

Thorsten Schroeder wrote "Instead, however, the developer has introduced a number of diagnostic and debugging features to ensure that all keystrokes are either broadcasted through a debugging interface or written to a log file in a public directory on the hard-drive."

This sort of debugging transforms the audio driver to a keylogging spyware. On the premise of meta-data of the records, the keylogger is believed to have being in existence on HP PC’s since December 2015.
