ORking, security> (From "TapewORm" in John Brunner' s novel "The Shockwave Rider", via XEROX PARC) A program that propagates itself over a netwORk, reproducing itself as it goes. Compare virus. Nowadays the term has negative connotations, as it is assumed that only crackers write wORms. Perhaps the best-known example was the Great WORm. Compare Trojan hORse. [Jargon File] (1996-09-17)
