W32/Agobot-EV is an IRC backdoor Trojan and peer-to-peer (P2P) worm which
opens TCP ports to listen for and process commands received from a remote intruder.
This worm will move itself into the Windows System32 folder under the
filename regsvc32.exe and create the following registry entries so that it can
execute automatically on system restart:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Generic Service Process = regsvc32.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Generic Service Process = regsvc32.exe
W32/Agobot-EV will attempt to terminate anti-virus and software firewall
processes, in addition to other viruses, worms or Trojans.
This worm will search for shared folders on the internet with weak passwords
and copy itself into them.
W32/Agobot-EV can sniff HTTP, VULN, FTP and IRC network traffic and steal data
from them. This worm can also exploit the DCOM vulnerability on unpatched
systems and manipulate registry keys.
This worm will attempt to test the available bandwidth by posting data to
the following sites:
yahoo.co.jp
www.nifty.com
www.d1asia.com
www.st.lib.keio.ac.jp
www.lib.nthu.edu.tw

www.belwue.de

verio.fr
www.utwente.nl
www.schlund.net
W32/Agobot-EV can also be used to initiate denial-of-service (DoS) and
synflood/httpflood/udpflood attacks against remote systems.
This worm can redirect TCP and GRE data and steal the Windows Product ID
and keys from several computer games.
W32/Agobot-EV maps several anti-virus and security-related websites to
localhost within the windows hosts file so that they appear unreachable
when a user tries to access them.
