More Information
W32/Agobot-JJ is an IRC backdoor Trojan and network worm.
W32/Agobot-JJ is capable of spreading to computers on the local network protected by weak passwords.
When first run W32/Agobot-JJ moves itself to the Windows system folder as
CSRS.EXE and creates the following registry entries to run itself on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Network = csrs.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Network = csrs.exe
Each time W32/Agobot-JJ is run it attempts to connect to a remote IRC server
and join a specific channel.
W32/Agobot-JJ then runs continuously in the background, allowing a remote
intruder to access and control the computer via IRC channels.
W32/Agobot-JJ attempts to terminate and disable various anti-virus and
security-related programs.
W32/Agobot-JJ will also hide all files starting with the string 'sound'.
