Technical Details

By connecting to the SQL server via port 1433, the worm exploits known security holes to gain access to a DOS prompt. After this the worm ftps binary files from a fixed host and executes them to spread further.The sites that hosted the carrier binary files have been taken down. In effect this stops the worm from spreading. This worm is not expected to cause further problems.[November 24, 2001; Mikko Hypponen, F-Secure Corp]
