Just to affirm this data, several of our servers are trapping the same packet(s). This worm has gained much power in a small amount of time and once again, has hit overnight and on a weekend.

Seemingly stems from this advisory by NGSSoftware Insight Security: http://www.nextgenss.com/advisories/mssql-udp.txt "Microsoft's database server SQL Server 2000 exhibits two buffer overrun vulnerabilities that can be exploited by a remote attacker without ever having to authenticate to the server."
