From; Sophos Alert System:
Name: W32/Agobot-RM
Aliases: Backdoor.Win32.Agobot.abq
Type: Win32 worm
Date: 18 April 2005
A virus identity (IDE) file which provides protection is
available now from the Sophos website, and will be incorporated
into the June 2005 (3.94) release of Sophos Anti-Virus.
Customers using EM Library, PureMessage or any of our Sophos
small business solutions will be automatically protected at
their next scheduled update.
At the time of writing, Sophos has received a small number of
reports of this worm from the wild.
Information about W32/Agobot-RM can be found at:
http://www.sophos.com/virusinfo/analyses/w32agobotrm.html
When first run, W32/Agobot-RM copies itself to the Windows system folder as
CRSS.EXE and runs this copy of the worm. The copy will then attempt to delete
the original file. In order to run each time a user logs on, W32/Agobot-RM will
set the following registry entries:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
CRSS
CRSS.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
CRSS
CRSS.exe
The worm runs continuously in the background providing backdoor access to the
computer.
W32/Agobot-RM will append entries to the HOSTS file in the <SYSTEM>\drivers\etc
folder. The file contains a list of websites each bound to the IP loopback
address. This prevents access to a list of anti-virus and security related
websites. For example,
127.0.0.1 sophos.com
127.0.0.1 www.sophos.com
The backdoor component of W32/Agobot-RM may be used to:
Initiate Denial-RM-Service (DOS) attacks.
Redirect GRE, TCP, HTTP, HTTPS, SOCKS4 and SOCKS5 traffic.
Download, upload, delete and execute files.
Set up an FTP file server.
Steal passwords (including PayPal account information).
List and kill processes.
Stop, start, pause and delete services.
Modify the registry.
Open and close vulnerabilities.
Port scan for vulnerabilities on other remote computers.
Flush the DNS cache.
Log keyboard presses.
Shut down and reboot the computer.
Add and delete network shares, groups and users.
Sniff network traffic for passwords.
Steal email addresses from the computer.
W32/Agobot-RM may alter the following registry entry in order to enable/disable
DCOM:
HKLM\SOFTWARE\Microsoft\Ole\EnableDCOM
W32/Agobot-RM is capable of adding and deleting the C$, D$, E$, IPC$ and ADMIN$
network shares.
W32/Agobot-RM may steal the Windows Product ID and keys from several computer
applications or games.
W32/Agobot-RM can be instructed to harvest email addresses from the infected
computer by searching the Windows Address Book, used by Microsoft Outlook and
Outlook Express. The worm can also harvest email addresses from Microsoft
Messenger.
W32/Agobot-RM will attempt to terminate a number of anti-virus and
security-related processes in addition to other viruses, worms and Trojans.
