Another possible source of inspiration — including the name “worm” — were the publications by John Shoch and Jon Hupp on programs they wrote at Xerox PARC around 1979-1980 and published in 1980 and 1982:

John F. Shoch and Jon Hupp:
 The “Worm" Programs — Early Experience with a Distributed Computation.
Xerox SSL-80-3 and IEN 159. May 1980, revised September 1980

John F. Shoch and Jon Hupp:
 The “Worm" Programs — Early Experience with a Distributed Computation.
CACM V25 N3 (March 1982)
