The Morris Worm source code in C – decompiled version

A nice analysis of the worm that was published shortly after the incident is <i>&quot;With Microscope and Tweezers: An Analysis of the Internet Virus of November 1988&quot;</i> by Eichin and Rochlis [1].<p>I was an intern at IBM UK at the time and I remember it caused quite a lot of interest, and perhaps confusion. The gateway between IBM&#x27;s corporate network (VNET, mainly) and and the (then) academic-only internet was shut down for a few days while people got a grip on exactly what was going on. Simpler times.<p>[1] <a href="http:&#x2F;&#x2F;www.ece.cmu.edu&#x2F;~ece845&#x2F;docs&#x2F;eichin.pdf" rel="nofollow">http:&#x2F;&#x2F;www.ece.cmu.edu&#x2F;~ece845&#x2F;docs&#x2F;eichin.pdf</a>

This appears to be a decompilation, not the original source.<p>However, it appears to be a very old decompilation, perhaps done while the worm was still live: <a href="https:&#x2F;&#x2F;github.com&#x2F;arialdomartini&#x2F;morris-worm&#x2F;blob&#x2F;master&#x2F;stubs.c#L4-L6" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;arialdomartini&#x2F;morris-worm&#x2F;blob&#x2F;master&#x2F;st...</a>

Morris is at YC, can&#x27;t he just post the source?

Jeez, has it been 30 years already?!?<p>I remember some folks in Berkeley (Bostic?) posting a patch to fix the bug in the worm! The worm was discovered because it kept infecting the same machines again and again; the patch fixed this bug. Ah, good times.
