Morris Worm

Good evening everyone!

HTS has been quite boring for the last few hours so here's something old: The Morris worm. One of the first widely successful internet worms released which infected 10% of the entire internet back in 1988.

Actually a pretty simple thing, it mainly used weak passwords, a buffer overflow, and a debug functionality to spread.

Worm's source code (reconstructed I'm assuming): http://www.foo.be/docs-free/morris-worm/worm/

A very good explaination of exactly how to worm works: http://www.snowplow.org/tom/worm/tour.html

What do you think of this worm? Terribly simple for the damaged it caused? A revolutionary step in the advancement of computer security? What about Morris' punishment for it?

Code: Select all
/* Ahhh, I just love these names.  Don't change them for anything. */
static struct usr *x27f28, *x27f2c;


I've been reading the code for a while now and get lost within 20 lines every time. I know I'm retarded, but don't tell me it's simple!
"Don't include a single line in your code which you could not explain to your grandmother in a matter of two minutes."

And of course... assume your grandmother is not Ada Lovelace.
