HP is selling more than two dozen models of laptops and tablets
that covertly monitor every keystroke a user makes, security
researchers warned Thursday. The devices then store the key
presses in an unencrypted file on the hard drive.
The keylogger is included in a device driver developed by
Conexant, a manufacturer of audio chips that are included in the
vulnerable HP devices. That’s according to an advisory published
by modzero, a Switzerland-based security consulting firm. One
of the device driver components is MicTray64.exe, an executable
file that allows the driver to respond when a user presses special
keys. It turns out that the file sends all keystrokes to a
debugging interface or writes them to a log file available on the
computer’s C drive.
