W32/Rbot-WN is a network worm with backdoor functionality for the Windows platform.
The worm copies itself to a file named cfgpwnz.exe in the Windows system folder and creates the following registry entries:
HKCU\Software\Microsoft\OLE
Wins32 Online
cfgpwnz.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Wins32 Online
cfgpwnz.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Wins32 Online
cfgpwnz.exe
W32/Rbot-WN 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-WN can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-WN 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
