About 9:30PM PST on January 25th, 2002, some SQL Server 2000
installations were compromised by some sort of SQL Server Worm. The
compromised boxes/worms generated more than 80Mbit of outgoing traffic
(probably more if our connection could have handled it) trying to
compromise other boxes it seems.
Those SQL Servers running Service Pack 2 or Service Pack 3 (released Jan
17 with little/no notice from MS!) were immune to the worm.
A quick sampling of sites that I know to be running MSSQL server quickly
showed the impact of this worm was huge. About 40% of the sampled sites
were down. Installation of the SP3 after compromise seemed to resolve
the issue. I'm not sure the nature of the worm, what it does to the
system outside of SQL Server, and whether trojans have been installed.
Another colleague noted a strange extended stored procedure running on
his home development server which was indeed taking up all the resources
of the box and busy scanning & connecting to other Ips.
Any confirmation/information from other sites would be appreciated.
