W32/Rbot-CR is a network worm and backdoor for the Windows platform. W32/Rbot-CR allows a malicious user remote access to an infected computer.
The worm copies itself to a file named taskmngrs.exe in the Windows system folder and creates the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Microsoft Update Machine =taskmngrs.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\Microsoft Update Machine =taskmngrs.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Microsoft Update Machine =taskmngrs.exe.
W32/Rbot-CR spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilites including DCOM-RPC, LSASS, WebDAV and UPNP and using backdoors opened by other worms or Trojans.
W32/Rbot-CR can be controlled by a remote attacker over IRC channels.
