Compromised Server? Can't figure out my logs!

Compromised Server? Can't figure out my logs!

Postby lbarlean » Tue Apr 15, 2008 4:41 pm

I've seen a couple of posts similar to my situation. Spam is being sent out with the "From" header line containing my user's email address so they are getting all of the bounced messages. This is happening with more and more frequency (3 already this week). I can't tell for sure if it's coming from our mail server.

Can anyone give me hint on how to read the logs?

for example here is one outgoing log entry that looks suspicious...

As much as I can tell is that nothing was added to the mail queue from this entry, but the fact that it is in the outgoing logs in the first place gives me concern.

Any advice would be greatly appreciated! Thank you!

Re: Compromised Server? How to tell from logs?

The best way to check to see how that mail got into your outmail log is to simple search the SMTP log for a matching SMTP recipient. This will then allow you to identify how the mail got into your system. I would also recommend searching the WebMail system as this also can generate mail. There are several ways these mails can legitmatly get into the system, and the most simpliest is that one of your users login details has been picked up by malicous software. Actions you can take include request that any effected user change their password, block the source of the mails (the IP) and also enable mail sending restrictions (group and smtp settings) to prevent the possibility of this esculating.

I so far haven't been able to find a matching entry in either the SMTP or the Webmail. Is that because the recipients were rejected?

The extract you have copied and pasted is from the outgoing mail log, and mentions the recipient 'pfspugjjfboo@boughnerart.com'. There are only 3 ways such a mail could make it into AMS and that is most likely the SMTP or WebMail (which could mean a comprised user account). Another possiblity however is if you use POP3 Retrievals. If you do then I will also recommend you examine those log files too. By default POP3 Retrievals is configured so it will only pull mail for local accounts but it is indeed possible to adjust the settings so that the mail pulled from the POP3 retrieval actually lands in the outgoing mail service.

I should also note while searching a log, you should look for: pfspugjjfboo@boughnerart.com

Hi Rob,
thanks for the reply & suggestions! I'm just getting back around to checking into this.
I checked the SMTP logs and webmail logs (searched for 'pfspugjjfboo' and manually read the log entries between 4am and 6am on the 15th of April). Nada. Nothing relating to this outgoing Mail entry. We also do not use POP3 retrievals. Here are the other logs for around this time...

I'm really at a loss. How can I find the compromised account if there is nothing in the logs?

Many of our employees use Sprint Mobile Broadband cards when on the road. that entry from the webmail ended 30 minutes before the offending email entry in our outmail log (the very first post).

I can agree the log extracts that you showed me contained nothing. One tip I would offer on searching the logs is to do a keyword search and search all the files. Due to the nature of outgoing mail queue, mails can be inserted hours before the appear in the logs (or at least when they reappear on a redelivery attempt). What I could recommend that to help in future to find such mails, you could create a content filter generated log for all mails passing through the system. Basically use the Add Text to File action and use the field tags ####CURRENTTIME####, ####FROMIP####, ####FROMADDRESS####, ####TOADDRESSCOMMALIST#### and ####CUSTOMEVENTSCOMMALIST####.
