More Information
W32/Rbot-ZJ is a worm which attempts to spread to remote network shares. It also contains backdoor functionality, allowing unauthorised remote access to the infected computer via IRC channels.
W32/Rbot-ZJ spreads to network shares as a result of the backdoor element receiving the appropriate command from a remote user.
W32/Rbot-ZJ moves itself to the Windows system folder as Compt.exe and creates the following entries in the registry so as to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Service Drivers
Compt.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Service Drivers
Compt.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Service Drivers
Compt.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices\
Service Drivers
Compt.exe
W32/Rbot-ZJ may delete network shares on the host computer. The worm may also attempt to disable access to anti-virus and security related web sites. W32/Rbot-ZJ also drops Troj/NtRootk-F as msdirectx.sys and installs it as a service with the name "msdirectx".
