In Germany, people are getting phone calls like this:
Hi, my name is XYZ, I'm from Microsoft.
We're receiving many errors and problem reports from your PC. I'm now here to help you fixing those problems.
Are you in front of the PC? Please open the URL XYZ in your browser. Download the repair tool and run it.
Click "Yes" on that dialog.
The "Yes" action will confirm the UAC dialog asking for administrator credentials, so the PC is basically lost and the software could do anything.
There is a local initiative called "elderly people in the Internet" and I'd like to enable the trainer (an elderly person himself) to demonstrate the participants what could happen in such a case (live demo).
So I am now looking for an open source (!) software that
- installs with a yellow UAC warning (unsigned)
- is not visible in the list of installed programs
- may be visible in the Task Manager process list and may be killed from there
- is able to uninstall completely
- runs from Windows 7 through Windows 10
- expose the file system to a defined remote host (list files, show content is not required)
- provides a key logger (may be limited)
- opens a remote desktop / VNC connection (view only)
The trainer will only use it in the classroom and will ensure that everybody uninstalls it when the class is over. But anyway, I'd appreciate if the software comes with some security considerations, e.g.
- software works only if the PC has a IP address of a specific subnet (e.g. 192.168.217.0/24) and was applied via DHCP
- software works only for a maximum of 4 hours and then uninstalls itself
Cost: ~50 €/ 60 USD are ok. Should be a perpetual license and required for the trainer only.
