I have a copy that someone else managed to snag. Jonathan, I'll send you
a copy in another email. If anyone else wants it, please feel free to
ask.
What I've come up with so far is this:
The vector appears to be a zip file that contains an HTML file. The HTML
file has, at the beginning of it, a base64-encoded executable of some
sort. Unfortunately, I lack the resources to analyze it further.
(Anyone have a good x86 disassembler or decompiler they'd like to
suggest?) The text of the document is output through javascript.
Presumably it uses this to execute the embedded executable. I'm told this
only works in IE but haven't seen fit to experiment myself. (Is this
behavior expected or is it a bug?)
I have been told that as of 8:30 BST (GMT+0100), the worms appeared to
have stopped. I would guess that this is some sort of timing routine
built into the worm. Whether or not it'll restart again remains to be
seen, but I haven't seen any activity for a while.
