Name: W32/Agobot-AAG
Aliases: WORM_GAOBOT.CT, Trojan.Win32.Pakes
Type: Win32 worm
Date: 6 June 2005
Sophos has issued protection for W32/Agobot-AAG.
At the time of writing, Sophos has received no reports from
users affected by this worm. However, we have issued this
advisory following enquiries to our support department from
customers.
Customers using EM Library, Enterprise Console, PureMessage or
any of our Sophos small business solutions will be automatically

W32/Agobot-AAG is an internet worm and IRC backdoor Trojan for the Windows
platform.
W32/Agobot-AAG spreads to other network computers by exploiting the buffer
overflow vulnerabilites LSASS (MS04-011) and RPC-DCOM (MS04-012) and by copying
itself to network shares protected by weak passwords.
W32/Agobot-AAG runs continuously in the background, providing a backdoor server
which allows a remote intruder to gain access and control over the computer via
IRC channels.
W32/Agobot-AAG includes functionality to:
- steal confidential information
- carry out DDoS flooder attacks
- silently download, install and run new software
- disable anti-virus and security related applications
When first run W32/Agobot-AAG moves itself to <System>\wmp9.exe and creates the
following registry entries to ensure it is run at system logon:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Nero Updater.6.12
wmp9.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Nero Updater.6.12
wmp9.exe
W32/Agobot-AAG modifies the HOSTS file, changing the URL-to-IP mappings for
selected websites, therefore preventing normal access to these sites. The new
HOSTS file will typically contain the following:
