Francesco, Any of the software you listed could be used to gain access to your server. Even the MailEnable software has had remotely exploitable buffer overflows. You did not mention software versions, or if the server was firewalled. If there is no firewall it could be a simple password guessing attack. The compromise of a windows account with admin rights or a SQL account with sufficient privilege would do it. If you have enabled auditing go over the logs carefully to look for any clues. Then wipe the machine and re-build it (or restore from a known clean backup) and make sure you change ALL the passwords - you never know what they did while they were there. Roger R.

I have a Windows 2003 Server running IIS 6, SQL Server 2000, MailEnable, and ASP.NET 1.1. WWW and FTP are enabled, but restricted by IP. FTP is additionally protected by authentication. Yesterday someone managed to access the server and dump 8GB of DVD files into a deeply nested folder in a backup directory, for sharing I presume. The payload folder was NOT within the available folders given access to FTP users. Someone was able to "see" the entire D drive and figure out a hidden enough location at their whimsy. I thought the server was fairly well locked down, but apparently not. What is the usual method of intrusion for "warez" attacks like these? Francesco
