I was under the impression that Teamviewer is a safe form of remote control as:
- all of its traffic is encrypted;
- searching for Teamviewer exploits does not turn up anything.
But I recently heard it is often used to install malware. Is it possible for a hacker to use a modified version of Teamviewer that doesn't show you its activity in order to install malware? I say a modified version because I thought Teamviewer only redirects output/input, so the user will always see what the connected person is doing.
Obviously a person can copy over a virus and run it, but you would see this happening so I don't count this as a method.
