The admins hand check the code for all the scripts to check for malicious code. It was not a virus in an SDN script.
If that is the case, I have no idea what happened, but I know it was not the client. Scan your computer for malware.
It could have been a RAT, they are used for remote access (hence their name) and can take control away from you if the RATer connected when he was doing the lure??? this is all highly unlikely though.......
