Finger
Finger Security Concerns: Provides key host info to attacker - Fingered host can be DOSd if hit with a recursive finger script till its memory and swap space fill. - Fingering clients can be DOSd if they finger a maliciously configured host (returns data overload - causing client to beep continually - etc.). - If fingering clients allow programmable keys - a maliciously configured host can return a finger response that maps a key to rm -rf /-. Disable on all host unless finger service is stubbed to only provide scripted data response (eg: system admin contact info - etc.).
Trojans that also use this port: ADM worm, Back Orifice 2000 (BO2K), CDK trojan (ports 79, 15858), Firehotcker (ports 79, 5321)
