More Information
W32/Rbot-BZ 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-BZ spreads to network shares with weak passwords as a result of the
backdoor Trojan element receiving the appropriate command from a remote user.
W32/Rbot-BZ moves copies itself to the Windows system folder as
ZONEALARM.EXE and creates registry entries called 'Microsoft Update Machine'
under the following keys in order to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
W32/Rbot-BZ may set the following registry entries:
HKLM\SOFTWARE\Microsoft\Ole\EnableDCOM = "N"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1"
