Hi there. Am 23:28 27.01.2004 -0600 teilte Floyd Hartog mir folgendes mit: ->Date: 01/27 16:03:28 Name: ATTACK RESPONSES id check returned root ->Priority: 2 Type: Potentially Bad Traffic ->IP info: 199.233.98.101:17335 -> XXX.XXX.XXX.XXX:25 ->References: none found SID: 498 -> ->Date: 01/27 16:52:21 Name: ATTACK RESPONSES id check returned root ->Priority: 2 Type: Potentially Bad Traffic ->IP info: 205.206.231.26:56101 -> XXX.XXX.XXX.XXX:25 ->References: none found SID: 498 -> ->Hi ->I am a bit confused with the output from my snort logs, which you see ->above. That looks bad, very bad. But a whois seems to indicate this is ->the vulnwatch and securityfocus outgoing mail servers. Am I reading ->this wrong? Is this a snort bug, or a attack? And what would be the ->correct response? Thanks for your imput. Floyd I'd believe you get mails containing the string "uid=0(root)". 25 is you smtp port on host XXX.XXX.XXX.XXX which probably is your mailserver. snort is just triggering on that string, because that *can* indicate someone is issuing the "id" command after having hacked the system. If above assumptions are correct and your mailserver still works, I'd believe you're green. hth, JO -- +---------------------------------------------------------------+ | __ __ __ __ _ _ just another pointless signature | | / _ \ V / -_) '_/ | | \___/\_/\___|_| | +---------------------------------------------------------------+ --------------------------------------------------------------------------- Ethical Hacking at InfoSec Institute.
