PC Cyborg Corporation (AIDS Trojan)
The 'licensor' named on the ransom demand of the AIDS Information Introductory Diskette, with a post-office box in Panama.
A front name for the first ransomware: ~20,000 floppy disks mailed in December 1989 that scrambled file names after 90 reboots and demanded $189 (or $378) for a 'licence renewal'.
In December 1989 about 20,000 floppy disks labelled 'AIDS Information Introductory Diskette' were mailed from London to a medical mailing list. The software counted reboots and after 90 hid directories and scrambled file names, displaying a demand to send $189 to PC Cyborg Corporation at a Panama post-office box for a licence. Joseph Popp, a Harvard-trained biologist who had worked with the WHO, was arrested by the FBI on 1 February 1990 and extradited to Britain, where he was found unfit to stand trial in 1991. The 'corporation' never existed beyond the box.
No company existed to penalise. Popp was charged with blackmail in Britain, found unfit for trial in November 1991 and returned to the US; he died in 2006. Nobody knows how many victims paid.
