Backdoor:W32/IRCBot.EX provides unauthorised access to an infected computer and also has the capability to spread to remote computers using the PnP exploit on port 445.
The backdoor's file is a PE executable file about 8 kilobytes long, packed with MEW file compressor and patched with PE_Patch.
This IRC-based backdoor-worm was found on August 15th, 2005 in Finland.
The backdoor has the ability to spread to remote computers using the PnP exploit on port 445. Please see the following page for detailed information on the vulnerability:
When the backdoor's file is activated on a computer, it copies its file to Windows System folder as MOUSEBM.EXE and then starts the copied file as a service named 'Mouse Button Monitor', described as follows: Enables a computer to maintain synchronization with a PS/2 pointing device.
