TCP Port 50002
About TCP Port 50002
Port 50002 is not assigned to any service in the IANA Service Names and Port Numbers Registry. This port falls within the dynamic/private port range, which IANA explicitly does not register; these ports are intended for ephemeral or temporary use. It is referenced in 2048 IDS rules and exhibits moderate malware activity indicators. Ports outside formal IANA assignment are commonly used by malware authors and security tooling.
IDS Rule References
2048 IDS / security rules reference TCP port 50002. Treat that number as context, not a danger score. Many detection rules are written against groups of ports rather than one service, web ports especially, so common web alternate ports inherit large counts while genuinely sensitive services can show few rules or none. Presence in IDS rules does not mean traffic on this port is malicious.
Rule categories (top 6): trojan-activity (730), web-application-activity (476), web-application-attack (344), attempted-recon (270), misc-activity (76), attempted-user (58).
