Hi,
I read the advisory from the Code Red Worm and I wonder how could a Executeable create a Process over the Network in an other Computers Memory (in Delphi)?

Cheers Micha

I have no idea how the worm gets code encoded as an
HTTP request to be loaded into memory as executable code.
It's pretty smart, though.

Without knowing the internal workings of IIS's DLLs, I think it'd be pretty difficult to create a remote process
without using some other existing 'listener' on the remote
machine to instantiate the process.
