    IIS/5.0 Attacked my Host - Sent email to admin

    hey guys, just wondering if this was ok to send to an admin in Thailand whos IIS/5.0
    system tried to attack my Apache 1.3.26 box (the banner was hacked to say Microsoft IIS/5.0) heheeh
    naughty admin i am.

    Hello,

    You do not know me but today my system recieved the following alert
    that appears to come from your box.

    -- snip snip

    Jul 30 04:44:19 securelinux snort[180]: [1:1002:2] WEB-IIS cmd.exe

    here is the packet payload from this incident

    Upon further investigation, I perfomed the following command to find out
    what version of the webserver was running.

    "telnet 168.120.21.34 80"
    and recieved this disturbing reply

    C:\WINNT\system32>
    C:\WINNT\system32>Cache-Control: bypass-client=205.251.201.172

    It looks like their is a remote backdoor bound to port 80, so when
    someone telnets to port 80 on your box, they are dropped into a remote
    shell, in this case, the c:\WINNT\System32> prompt giving the
    attacker(s) full access to your machine. NOT GOOD!.

    As you can see, your machine has been compromised
    *NOT BY MYSELF OR ANYONE AFFILIATED WITH ME WHATSOEVER*
    most likely by the Microsoft IIS 5.0 "Web Server file request parsing
    vulnerability" or
    more commonly "Unicode Attack".

    Perhaps an intruder manually compromised your machine or it was
    compromised by
    a code red or code red version 2 worm. Its not clear at this point.

    Let me state this one more time, I did not compromise your host, im just
    a linux network administrator thats trying to do a good deed here,.

    Please contact me ASAP when you recieve this email.

    P.S - If you get this emai, dont panic, and DO NOT shutdown your
    machine, perform these commands
    and save the output to a floppy disk. Your going to want to hunt down
    who did this and these following commands will help forensic
    investigators

    also grab a pen and a notepad, write down the date, time, and every
    command your typed, also sign it, date it, and place it with your floppy
    disk, then take this evidence to the police.

    c:\WINNT\System32> date
    c:\WINNT\System32> time
    c:\WINNT\System32>netstat -an
    c:\WINNT\System32>nbtstat -c
    c:\WINNT\System32>dir /t:a /a /s /s:d c:
    c:\WINNT\System32>dir /t:w /a /s /o:d c:
    c:\WINNT\System32>dir /t:c /a /s /o:d c:
    c:\WINNT\System32>fport (www.foundstone.com) download it and run it
    c:\WINNT\System32>pslist (www.sysinternals.com) download it and run it
    c:\WINNT\System32>Auditpol
    c:\WINNT\System32>Loggedon
    c:\WINNT\System32>dumpel -t -l system
    c:\WINNT\System32>dumpel -t -l application
    c:\WINNT\System32>dumpel -t -l security
    c:\WINNT\System32>pwdump2
    c:\WINNT\System32>regdump

    thats about all, remember to download fport and pslist to get a listing
    of all the applications running etc.
    remember to save the output of each command to a floppy disk.

    remember to write down EXACTLY what you did, what you typed, the date,
    the time etc..

    Im sorry I had to be the bearer of bad news

    contact me soon if you require further assistance

    Your Truly

    Kurt Pomeroy

    yea that should about cover it. I doubt person will go to the authorities but i hope he/she at least fixes the problem. I went to the site in browser and got pretty much the same thing. Could not connect threw telnet though. I might have just messed up but i dont really have the time to keep trying. Anyways interesting read

    *****UPDATE******
    The server is actually down now so I am assuming that they got your email and just turned the box off.
