P. Capek, David M. Chess, Steve R. White, Alessandro Fedeli · IEEE Security & Privacy · 2003
A computer worm disguised as a benign holiday greeting spread rapidly via email and clogged up networks worldwide.

This article reviews 1987's relevant global networking environment, the way the Christma worm spread, the events surrounding its worldwide propagation, and the surprising effect it had once it got inside IBM.
