Last week BleepingComputer covered how some
HP laptops have a keylogger, or really a debug trace, in a certain version of the the Synaptic keyboard driver. While the driver's ability to log keystrokes was disabled by default, it is still a serious security risk that should be fixed on all users of HP laptops.
Before we get started explaining how to check your system for this particular driver, it is important to note that the keylogging was not placed in the driver for malicious reasons. It appears that it was instead being used by the driver developers to help them find bugs in the driver while it was being developed. Unfortunately, by mistake this debug trace function was not removed from the driver before it was released for production.
With that said, if you have an HP laptop, you may be wondering if your laptop has the driver installed that contains this debug trace, or keylogging, feature. To see if you have the affected driver, you can go to the C:\Windows\System32\drivers folder and look at the properties of the
SynTP.sys driver as shown below.
If the Product version is listed as
19.3.11.37 16Aug16, then you have the driver installed that contains the keylogging/debug trace feature.
