More Information
W32/Rbot-BJU is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-BJU spreads:
- to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012)
- by copying itself to network shares protected by weak passwords
W32/Rbot-BJU runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/Rbot-BJU copies itself to <System>\winlogi.exe with the hidden file attributes.
The following registry entries are created to run winlogi.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
virtual-ie
winlogi.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
virtual-ie
winlogi.exe
The following registry entry is set:
HKCU\Software\Microsoft\OLE
virtual-ie
winlogi.exe
