Don't ask me, I've never done nuffin with them sinks.... Where am I supposed to find those files? -----Original Message----- From: John Tolmachoff (Lists) [mailto:johnlist@xxxxxxxxxxxxxxxxxxx] Sent: Tuesday, October 28, 2003 9:46 PM To: [ExchangeList] Subject: [exchangelist] RE: Exchange 2k hacked http://www.MSExchange.org/ If it is an event sink, you should be able to open up the files, as I believe event sinks must use a .vbs, correct? John Tolmachoff Engineer/Consultant/Owner eServices For You -----Original Message----- From: Mark Hippenstiel [mailto:M.Hippenstiel@xxxxxxxxxxxx] Sent: Monday, October 27, 2003 1:03 PM To: [ExchangeList] Subject: [exchangelist] Exchange 2k hacked http://www.MSExchange.org/ Today I had to resurrect an exchange 2k server that had relaying for successfully authenticated hosts allowed. This wouldn't have been a problem, had the user 'webmaster' had a password assigned :) I guess this was some left-over from a previous Novell migration. Well. I cleared out half a million spam emails. What got to me was the presence of a process named unsecapp.exe which I have not noticed running anywhere before. A quick google returns some references to event sinks. Further, there have been various dcom errors, stating an access error while starting a {3Dxxxx... application. All this could be perfectly legit, but I want to make sure that this host has not been tampered with. The exchange is running behind ISA and has only SMTP published. The SMTP vuln had been fixed on the 24th I think. Any clues? Thanks!
