W32/Rbot-BC is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality, allowing unauthorised remote access to the infected computer via IRC channels while running in the
background as a service process.
W32/Rbot-BC spreads to network shares with weak passwords as a result of the backdoor Trojan element receiving the appropriate commands from a remote user.
W32/Rbot-BC copies itself to the Windows System32 folder as
DOSPRMWIN.EXE and creates entries in the registry at the following locations
to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Micro Process = dosprmwin.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Micro Process = dosprmwin.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Micro Process = dosprmwin.exe
