MYSTERY DISKS INUNDATE POSTAL SYSTEM: PANIC OVER CYBORG LOCKOUTS

By John Markoff

LONDON — Panic hit corporate offices, government desks, and medical research institutes across Europe and North America this week following the unexplained arrival of thousands of unmarked black 3.5-inch floppy diskettes.

Distributed via physical mail postmarked from London, the diskettes carry a printed label reading “AIDS Information — Introductory Diskette” and claim to contain interactive epidemiological databases. However, once loaded onto IBM-compatible personal computers running MS-DOS, the software silently monitors system usage.

Upon reaching 90 system reboots, the program executes a primitive file-scrambling routine. The software locks root directory structures, hides system files, and displays a ransom demand forcing users to mail $189 to PO Box 270 in Panama City to receive an unlocking key. It represents the first large-scale digital extortion scheme recorded in computing history.
