Is Sapphire the world's smallest computer worm?

["Richard M. Smith" <rms () computerbytesman com>]

At 376 bytes, is this new Sapphire worm the world's smallest computer
worm?  The only competition I can think of is the Morse worm.  Anybody
know how big it was?

yeah.  i guess it's an old vulnerability, but i don't keep up on
this stuff.

however, i have disassembled the code inside; all it does is send
itself to pseudorandomly generated hosts.

there is an annotated disassembly at
