Via Langreiter.com: Well Written Worm, check out the MS SQL Worm Disassembly
It's a thing of terrorbeauty, this Slammer/Sapphire/W32.SQLExp.Worm. Weighing in at 376 bytes of assembly language code, it is shorter than some email signature blocks. Shorter than the next paragraph.
It fits entirely within one UDP packet. The packet goes into a Microsoft SQL Server box, and boom, the machine turns into a zombie, spewing the same packet back out at random IP addresses, over and over and over and over, running in a tight 23-instruction loop, cycling fast enough to fill the network it's connected to with the tiny replicates of itself directed anywhere and everywhere on the net.
I noticed this earlier today, but Chris also points out that MySQL 4.1 "The Subselect Edition", was recently announced.
Oh, one more thing. Looks like Open Watcom RC1 has been released. Wow.
