toch weer storm op het net

Internet storm center meldt
Increased scanning activity is principally attributed to the release of the Welchia.B.Worm on or about Wednesday February 11th. ISC/DSHield data indicate that there were approximately 40,000 systems scanning for Port 80 last Tuesday February 10th 2004 and that number increased over the next few days to a peak number of 377,089, a whopping increase of 337,089 systems. Over a similar time period scans of Port 445 increased from approximately 75,ooo systems scanning to a peak of 331,901 on 02/15/04, an increase of 256,901 systems. Welchia.B exploits multiple Windows vulnerabilities by attacking TCP port 135, TCP port 80, and two vulnerabilities on TCP port 445.
 
Dit soort traffiek kan niet worden tegengehouden door routers. het is vervuiling van het dataverkeer waar we niets aan kunnen doen.
