Chances are one of the emails you received from that host contained the string uid=root. It could have been a mailing list discussion or something similar. That's a common FP. I would still try to find the packet captures and make sure. The location really depends on how you launch snort. Is it logging in pcap format to a file, or just in quick format, or in full format creating a directory for each source/destination. BTW, you really shouldn't portscan hosts that you are not in charge of. People don't like that very much. As for nmap reporting all UDP ports open, it's probably a good thing as opposed to a bad thing, due to the nature of how nmap works. It sends a UDP packet to the port, if it doesn't get a response, it assumes that the port is open. However, there may be some sort of a filtering device blocking the packet. If you see ALL UDP ports open, it's very likely that it's a False Positive. Laterz On 21 Jun 2004 19:09:07 +0530, Sanjay Arora <skpobox () hotpop com> wrote:
I am running a small Lan with IPcop with one server on DMZ. Gateway address to my ISP is 172.16.0.1, obviously Iḿ behind a NAT server. I myself use IP addresses 192.168.200.x & 192.168.100.x for my Green & DMZ interface respectively. Today, while checking the logs (I had not done that for a few days), I found the following log on the 17th of this month: Date: 06/17 20:41:25 Name: ATTACK RESPONSES id check returned root Priority: 2 Type: Potentially Bad Traffic IP info: 66.54.152.7:110 -> 172.16.0.141:32786 References: none found SID: 498 Checked out SID 498 on Snort.org and found: SID 498 Message ATTACK-RESPONSES id check returned root Signature alert ip any any -> any any (msg:"ATTACK-RESPONSES id check returned root"; content:"uid=0|28|root|29|"; classtype:bad-unknown; sid:498; rev:6;) Summary This event is generated by the use of a UNIX "id" command. This may be indicative of post-compromise behavior where the attacker is checking for super user privileges gained by a sucessful exploit against a vulnerable system. Impact Serious. An attacker may have gained super user access to the system. Detailed Information This event is generated when a UNIX "id" command is used to confirm the user name of the currenly logged in user over an unencrypted connection. This connection can either be a legitimate telnet connection or the result of spawning a remote shell as a consequence of a successful network exploit. The string "uid=0(root)" is an output of an "id" command indicating that the user has "root" privileges. Seeing such a response indicates that some user, connected over the network to a target server, has root privileges. Affected Systems Attack Scenarios A buffer overflow exploit against an FTP server results in "/bin/sh" being executed. An automated script performing an attack, checks for the success of the exploit via an "id" command. Ease of Attack Simple. This may be post-attack behavior and can be indicative of the successful exploitation of a vulnerable system. False Positives This rule will generate an event if a legitimate system administrator executes the "id" command over an unencrypted connection to verify the privilege level available to him. This rule may also generate event by viewing the documentation on snort.org. The web site www.bugtraq.org serves a non-standard HTTP header of the form "X-Mandatory-Snort-Alert: *GOBBLE* uid=65534(nobody) uid=0(root)" browsing this site will generate an event. If you think this rule has a false positives, please help fill it out. False Negatives None Known If you think this rule has a false negatives, please help fill it out. Corrective Action Ensure that this event was not generated by a legitimate session then investigate the server for signs of compromise Look for other events generated by the same IP addresses.

accurate OS guess Nmap run completed -- 1 IP address (1 host up) scanned in 3282 seconds What I very nearly did not notice was the hostname. mail.softhome.net...one of my own free pop3 provider, though not the one from which I subscribe to this mailing list. Now my question is: - How serious is this? Am I really compromised? Are stateful iptables firewalls like IPcop really so easy to get through. I have port forwarded only the http & smtp ports. I am using qmail, so sendmail bugs are out. Also, as my dmz is only a test site till I get a real ip from my ISP, the dmz webserver was shut down on that day. - What do I do? Check for something or straightaway reinstall ipcop so that any rootkits etc. are destroyed? - What about my Green Zone? What precautions should I take? - Where does Snort store the actual packet that triggered this response? I could not find it in the dir of this ip address in my /var/log/snort! - How do I tackle this pop3 provider? Is he hacking? or is he hacked himself? I haven´t scanned his other ips pop,mail,www aliases which each have their own ips. Please help.
