More Information

W32/Rbot-MB is a network worm and backdoor Trojan for the Windows platform.

W32/Rbot-MB allows a malicious user remote access to an infected computer.

In order to run automatically when Windows starts up W32/Rbot-MB creates the following registry entries:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Sygate Personal Firewall Start = services32.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Sygate Personal Firewall Start = services32.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Sygate Personal Firewall Start = services32.exe

W32/Rbot-MB 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-MB can be controlled by a remote attacker over IRC channels.
