Keylogger Discovered on Hundreds of HP Laptops

You should fix this via a patch update if you’re affected. This is sadly not the first time that HP has been discovered to have shipped their computers with significant vulnerabilities either.

Hewlett Packard has issued an emergency patch to resolve a driver-level keylogger discovered on hundreds of HP laptops.

The bug was discovered by Michael Myng, also known as “ZwClose.” The security researcher was exploring the Synaptics Touchpad SynTP.sys keyboard driver and how laptop keyboards were backlit and stumbled across code which looked suspiciously like a keylogger.

In a blog post, ZwClose said the keylogger, which saved scan codes to a WPP trace, was found in the driver.

While logging was disabled by default, given the right permissions, it could be enabled through changing registry values and so should a laptop be compromised by malware, malicious code — including Trojans — could take advantage of the keylogging system to spy on users.
