Detection & IOCsextracted from sources · hover to see the quote

portTCP/1801
  • Check for the Windows Message Queuing service ('Message Queuing') running and TCP port 1801 actively listening — this is the prerequisite attack surface for CVE-2023-28250 exploitation.
  • Exploitation requires the Windows Message Queuing service to be enabled in a PGM Server environment; monitor for unexpected enabling of this service via Control Panel or service management APIs.
  • Alert on inbound specially crafted network traffic targeting TCP/1801 (MSMQ) on hosts where the Message Queuing service is running, as the attack vector is a specially crafted file sent over the network.
  • ·The vulnerability is only exploitable when the Windows Message Queuing service is enabled and running in a PGM Server environment; systems without this service enabled are not at risk.
