Keylogger Found in Audio Driver of HP Laptops, Says Report (bleepingcomputer.com) 116

An anonymous reader writes: The audio driver installed on some HP laptops includes a feature that could best be described as a keylogger, which records all the user's keystrokes and saves the information to a local file, accessible to anyone or any third-party software or malware that knows where to look. Swiss cyber-security firm modzero discovered the keylogger on April 28 and made its findings public today. According to researchers, the keylogger feature was discovered in the Conexant HD Audio Driver Package version 1.0.0.46 and earlier. This 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 via a Scheduled Task every time the user logs into his computer. According to modzero researchers, the file "monitors all keystrokes made by the user to capture and react to functions such as microphone mute/unmute keys/hotkeys."

              I wrote a driver for multimedia, including volume keys, over 10 years ago and yes, I did include a key logger functionality in the debug build. That said the only keys I logged were the 'special', non ascii keys. I might have logged all keys on the very early stages of the driver development but I had absolutely no need to capture any of the 'writing' keys and if I wanted to record activity on these I would probably have recorded the event but not the actual character pressed.

Lots of funny stuff like that, I suppose you could have some reasonable (islower(c) || isdigit(c)) logic that skips logging at least most of the alphanumeric keys. or you can do if (c >= 0x80) and that will leave out all the alphanumeric keys, a few of the symbols, the numpad, and a few

        One reason would be to replay a sequence of keystrokes to verify that a bug has been fixed.

        My company has an internal app that logs input (keystrokes, mouse movements). If the program crashes, the keylog is emailed along with the stack trace to the responsible programming team. This has been a wonderful help for debugging and is WAY more useful than user descriptions of what they were doing. We can see what caused the fault, and after fixing the problem we can replay the input to verify that it is fixed. However, it only records input when this app has the focus, and users are informed that their input is being recorded.

          For this type of product, storing that data might actually make sense to keep. The problem is not that the data is being stored, but rather that it is being stored on disk where anybody with the right access privileges can trivially get to it.

          Debug logging is the perfect use case for an in-memory ring buffer. That approach ensures that the data is relatively hard to access (i.e. that it can be accessed only by your debugging tool that knows the magic handshake or whatever). It also ensures that the data

        it looks like they intended to log the pressing of the volume and mute keys, probably to make sure they were being captured and responded to accurately and reliably. So when the beta tester tells you "the music was playing when I left for lunch but when I came back it was silent so I rebooted it", they can look at the logs and verify that no, right about the time you left for lunch you pressed the Mute button whilst trying to turn off the wifi.

      Stupidity. It is far too obvious (if anybody bothers to look) for anything else. Basically, you type a random number in and then search for it on disk. The only protection against detection it has is that most people do not assume developers are quite this extremely stupid. After Intel last week, I think we can safely assume that even software from big names can contain utterly demented mistakes that are a catastrophe for security.

    • Stupid is, as stupid does.
    • Well, HP should be able to answer that quite easily. I assume that they at least use version control. That should reveal the exact employee who create the logging code. And every person who signed off on the code reviews. And all the chat messages between employees and managers.

      It should not be hard for the company to find out what happened... unless the thing was approved by management in some sort of espionage agreement.
