Dealing with Rustock…

Man, this morning sucked.  My uncle was calling me  saying that they can’t send email to anyone…I was like…yeah right…however it was true.  I went to mxtoolbox and ran a blacklist check…sure enough his email server was on a 8 blacklists.

The CBL blacklist said it was very characteristic of the rustock spam bot.  Now I was sh*ting a brick.  Great…30 workstations + a rootkit + no time = a very bad situation.

How did I resolve the situation in under 5 min….firewall rules!

I basically made a rule that blocks SMTP traffic outbound from all IP Addresses except their exchange server.  Problem solved.

Currently they are only listed on 2 blacklists (small ones) and they’re able to send email again.  Rustock is still there, but I’ll deal with it tonight.

Anyway, just thought I’d share that.  L8tr
