Description

RDP is used by attackers to laterally move to new hosts. Standard processes do not usually implement RDP on their own, and attackers might inject or tunnel using a non-standard process.

Attacker's Goals

Use an account that was possibly compromised to gain access to the network.

Investigative actions

  • Validate if the process is a legitimate IT software.
  • Verify if the process is known to be malicious.
  • Look into actions done on the remote host.
