More Information
W32/Sdbot-ACE is a network worm and IRC backdoor Trojan for the Windows platform.
When first run W32/Sdbot-ACE copies itself to the Windows system folder as sessionmgr.exe. W32/Sdbot-ACE creates the following registry entries in order to run on user logon:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
irc session = "sessionmgr.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
irc session = "sessionmgr.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
irc session = "sessionmgr.exe"
The worm spreads through network shares protected by weak passwords. The filename used when spreading through network shares is "session.exe"
The backdoor component of W32/Sdbot-ACE joins an IRC channel and awaits commands from a remote user. W32/Sdbot-ACE can then be instructed to perform tasks such as to:
take part in distributed denial of service (DDoS) attacks
download/execute arbitrary files
scan networks for vulnerabilities
steal product registration keys for certain software
send email
