PC fraud by changing properties

  1. Aug 10, 2017 #1
    How can some PC scammers change the properties of a pc and its device manager to sell it to a high price? How can show another PC's device manager as that of the another PC?

    Thank you.

    If there was a way to put it up there, there's a way to change it. I'd guess it's somewhere in the registry.

    Isn't it a simple and well-known method? I suspect that the swindler might take an academic position in an instutition. I have some clues even though they are weak.

    Thank you.

    Sounds like something you need to handle personally.

    Yes but I am wondering a lot about this trick.

    Thank you.

    I've never heard of this in 18+ years in computer security, but I can think if two ways this may be accomplished:

    - Malware code that hijacks the execution of the Device Manager interface to present false information (third-party tools like Speccy would not be affected).
    - Sophisticated rootkit that intercepts the Windows hardware API calls.​

    In either case, most modern antivirus programs would detect this behavior.

    It was a win 7 notebook, it was like every part of interface was fake. The wireless symbol had a strange behavior. The device manager, control panel and right-clicking on my computer symbol was working properly and I could enter the harddisk. When I shutdown the monitor after turning it and clicking win symbol the operating system was still working properly i.e it could pass to the sleep mode. But when I shut down the pc properly and re-start it didn't boot instead gave the notification of PXE-E61:Media test failure, check cable.

    1. Do you think this is still a job of a virus or rootkit?

    2. Is this a simple trick?

    3. Can the swindler be a programmer and created a completely fake interface?

    Thank you.

    Did you look... here ?

    Without any pictures of the interface, it's easy to speculate about all kinds of possibilities, like a Windows-like Linux distribution.

    The PXE boot error means there is no bootable device, so the system may have been booted from a Linux USB, with no OS installed on the hard disk.

    A fake-looking interface and not being able to reboot seems like a good indicator the system is being misrepresented.
