More Information
W32/Rbot-AGP is a worm with backdoor functionality for the Windows platform that spreads to other network computers by exploiting a number of known vulnerabilities and by copying itself to network shares protected by weak passwords. W32/Rbot-AGP is a worm with backdoor functionality for the Windows platform that spreads to other network computers by exploiting a number of known vulnerabilities and by copying itself to network shares protected by weak passwords.
W32/Rbot-AGP runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
W32/Rbot-AGP includes functionality to access the internet and communicate with a remote server via HTTP.
Once executed W32/Rbot-AGP moves itself to the file <Windows system folder>\scrnsaver.scr, and in order to be able to run automatically when Windows starts up sets the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Screen Saver
scrnsaver.scr
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Screen Saver
scrnsaver.scr
When W32/Rbot-AGP is installed it creates the file <Windows system folder>\svkp.sys which is a legitimate driver for NT based systems.
The file SVKP.sys is registered as a new system driver service named "SVKP", with a display name of "SVKP" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\SVKP\
