W32/Rbot-RU is a network worm which attempts to spread via network shares. The worm contains backdoor functions that allow unauthorised remote access to the infected computer via IRC channels while running in the background.

The worm spreads to network shares with weak passwords and also by using the LSASS security exploit (MS04-011) and the RPC-DCOM security exploit (MS03-039).

When run W32/Rbot-RU moves itself to the Windows System folder as a hidden, read-only, system file named devcpp.exe.

The worm then creates the following registry entries so as to run itself on computer logon:

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Dev Gnu Cpp
devcpp.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Dev Gnu Cpp
devcpp.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Dev Gnu Cpp
devcpp.exe

Once installed, W32/Rbot-RU will attempt to perform the following actions when instructed to do so by a remote attacker:

scan ports
delete network share folders
participate in distributed denial of service (DDoS) attacks
download and run files from the internet
steal CD game keys
log keystrokes
capture clipboard data
create an HTTPD server
create a SOCKS4 server
perform DCC file transfers over IRC channels
capture screen displays and images from web cameras
login to SQL servers and send EXEC commands to open a command shell on the server
