- internet worm — (networking, security) The November 1988 worm perpetrated by Robert T. Morris. The worm was a program which took advantage of bugs in the Sun Unix sendmail program, Vax programs, and other security loopholes to distribute itself to over 6000 computers on the Internet. The worm itself had a bug which made it create many copies of itself on machines it infected, which quickly used up all available processor time on those systems. Some call it "The Great Worm" in a play on Tolkien (compare elvish, elder days). In the fantasy history of his Middle Earth books, there were dragons powerful enough to lay waste to entire regions; two of these (Scatha and Glaurung) were known as "the Great Worms".
