New viral imagespam discussion

This iteration is a bit more interesting, I've uploaded a sample here:

How is this supposed to work?  The previous GIF script relied on the JScript parser not caring much about the initial bytes, or whatever, but what about this?  I can't see how running this as a BAT file would do anything, I'm not going to try it out of course.

Bah, I'm off to read the GIF specification.

Looks like it's abusing \0s to make the Winders .bat parser treat the whole command as one line (it's spread over multiple `lines', as you can see)

Also, my image validator doesn't seem to like it! (See the GIF specification about block sizes and block types.)

Apparently, the Windoze BAT parser is ignoring everything that isn't surrounded by CRLF and a NULL character. For instance:

0D 0A 65 63 00 0D 0A 68 6F 00 0D 0A 20 74 00 0D 0A 65 73 00 0D 0A 74 20 00

is interpreted as

echo test

If these image formats were XML-based, this wouldn't happen.

What kind of tard uses floating points for colors!

What manner of turd uses exclamation marks for rhetorical questions‽

If running it actually does do something more than make the parser spew syntax errors (someone try it in a VM...), then I have greatly underestimated the intelligence of /b/tards.
