Well, I have had my first run-in with a hacker, or was it a virus? I'm not 100% sure.. Guess I should start from the beginning... A days ago, I began to get user complaints on the slowness of the internet. I figured it was mostly them just wanting something to complain about, so I did what all crappy admins do, I ignored it. Well, last night the box was rebooted after some software was updated. Today people were complaining about how PAINFULLY slow the internet was, so I looked at the proxy server. NT4 running proxy3. I know, there is newer better stuff, but its what I have to work with. :) SO... I looked at the processes and noticed the CPU hovering at 35-50%.. Way too high. So a quick look at the process list showed two things that I didn't remember needing to be there, win.exe and start.exe. Next move was to find them, and they were in the winnt\system\ folder. What I also found odd was that there were three new folders in that directory all created on the 8th, NT, tools, and win. Here are the contents, respectively. 1. 1fg.dll, 1gno32.dll, 1s.dll, 1t.exe(antivirus sees this one as a backdoor Trojan), 132.dll, 1gn32.dll, 1idv32.dll, 1sf32.dll, 1ygwin1.dll (says it's a Cygwin POSIX Emulation DLL), 132.dll.bkup 2. temp, servUDaemon.ini, services.exe, servUStartUpLog.txt, in, srvss.exe, start.exe, BugSlayerUtil.dll (says it's a Bugslayer Utility Routine), and _zoLibr.dll 3. (folder) FL, cygwin.dll, MS.dll, secure.bat (see below), temp, x32.dll, cfg.dll, IGNo32.dll, secure1.bat (see below) pidv32.dll, win.exe, x32.dll.bkup SO, anyone know what I have or what hit me? From looking at the sercure and secure1 batch files, it looks like a root kit... But I'mm new at this side of security I'mm aCiscoo guy...) Last thing, the logs show that the attacker was hitting the \scripts\sample\ folder... Meaning I think he was trying to use the old IIS Sample Scripts to execute local code... Not sure if he was successful... Thanks in advance!!
