More Information
W32/Rbot-ABN is a network worm with backdoor Trojan functionality for the Windows platform.
The worm copies itself to a file named winsN2S.exe in the Windows system folder and creates the following registry entries to run itself on system restart or logon:
HKCU\Software\Microsoft\OLE
Windows NetStart Service2
winsN2S.exe
HKCU\System\CurrentControlSet\Control\Lsa
Windows NetStart Service2
winsN2S.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Windows NetStart Service2

W32/Rbot-ABN spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilities (including DCOM-RPC, LSASS, WebDAV and UPNP) and using backdoors opened by other worms or Trojans.
W32/Rbot-ABN can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-ABN can be instructed by a remote user to perform the following functions:
start an FTP server
start a Proxy server
start a web server
take part in distributed denial of service (DDoS) attacks
log keypresses
capture screen/webcam images
packet sniffing
port scanning
download/execute arbitrary files
start a remote shell (RLOGIN)
steal product registration information from certain software
Patches for the operating system vulnerabilities exploited by W32/Rbot-ABN can be obtained from Microsoft at:
MS04-012
MS03-039
MS03-007
MS01-059
