Today I opened TCPView to see what was causing a lot of outbound network activity and could only identify svchost.exe on port 3389 (which i understand to be the port used by remote desktop).
I ended the process almost immediately.
I've searched for the IP address it was connected to, and discovered it originates in South Korea.
I have just discovered in the Windows Event Viewer under "Applications and Services Log > Microsoft > Windows > TerminalServices-RemoteConnectionManager" almost 2,000 events which read similar to:
Remote Desktop Services: User authentication succeeded: User: administrator Domain: Source Network Address: 22.214.171.124
This goes on with users such as sales3, secret3, shop3 - all succeeded.
I wanted to know as it seems my system has been compromised; is at all possible for me to track any activity, such as file access/modification.
And can anyone advise on the best course of action to take to prevent this happening in future?
Bummed me out of my festive spirit
