I looked over eeye.com's reverse engineering of the worm that did the SQL Slammer (given the name, "Sapphire Worm") on Jan. 25, and it's elegant, not quick and dirty. Reference: http://www.eeye.com/html/Research/Flash/sapphire.txt

SANS Top-20 Entry: W2 Microsoft SQL Server (MSSQL) http://isc.sans.org/top20.html#w2 The Microsoft SQL Server (MSSQL) contains several serious vulnerabilities that allow remote attackers to obtain sensitive information, alter database content, compromise SQL servers, and, in some configurations, compromise server hosts. MSSQL vulnerabilities are well-publicized and actively under attack. Two recent MSSQL worms in May 2002 and January 2003 exploited several known MSSQL flaws. Hosts compromised by these worms generate a damaging level of network traffic when they scan for other vulnerable hosts.

This port is used by the SQL Slammer or Sapphire worm. See 'analysis' section on homepage. Worm started at 12:30 AM January 25th. It is targeting MS-SQL servers on port 1434 (UDP).

Observed 30 probes in 30 minutes from 30 sources -- all source port 69 to destination 1434 UDP. Probes continuing as I write this at the same pace. First probe at 21:35 Pacific time.
