Your HP laptop may be secretly recording everything you are typing on your keyboard.
Swiss cyber-security firm modzero discovered the keylogger on May 19 2017 and made its findings public today. HP Audio Drivers contains keylogger vulnerability that can be abused by hackers and steal user information by keeping log of your key strokes on the target system.
According to Modzero researchers, the keylogger feature was discovered in the Conexant HD Audio Driver Package version 126.96.36.199 and earlier. It is an audio driver that is preinstalled on HP laptops. One of the files of this audio driver is MicTray64.exe (C:\windows\system32\mictray64.exe).
This file is registered to start through a Scheduled Task every time the user logs into his computer. According to researchers, the file “monitors all keystrokes made by the user to capture and react to functions such as microphone mute/unmute ,keys/hotkeys.”
The problem is that this file writes all keystrokes to a local file at:
If the file doesn’t exist or a registry key containing this file’s path does not exist or is corrupted, the audio driver will pass all keystrokes to a local API, named the OutputDebugString API.
A malicious software installed on the computer, or a person with physical access to the computer, can copy the log file and have access to historical keystroke data, from where he can extract passwords, chat logs, visited URLs, source code, or any other sensitive data.
The researchers said they found the Conexant HD Audio Driver Package is preinstalled on 28 HP laptop models. Other hardware that uses this driver may also be affected. The models that are affected are listed below:
