Vulnerable Ports

This list (a very small part of our SG Ports database) includes TCP/UDP ports currently tested by our Security Scanner, and corresponding potential security threats. We update the list on a regular basis, however if you feel we should add other port(s) to the list or modify their descriptions, please . Any feedback and suggestions can also be posted to our Network Security forum.

Port(s) Protocol Service Scan level Description
 32811 tcp retp not scanned IANA registered for: Real Estate Transport Protocol
 32879 tcp malware not scanned Trojan-Proxy.Win32.Ranky.gen / Unauthenticated Open Proxy - the malware listens on TCP port 32879. Third-party attackers who can connect to the infected system can relay requests from the original connection to the destination and then back to the origination system. Attackers may then be able to launch attacks, download files or port scan third party systems and it will appear as the attacks originated from that infected host.
