W32/Rbot-AA 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-AA spreads to network shares with weak passwords as a result of the
backdoor Trojan element receiving the appropriate command from a remote user.
