Victims were instructed to mail their money to a PO box in Panama. The fees were $189 for a year’s “lease” or $378 for a lifetime “lease.” When adjusted for inflation, this comes out to roughly $400 and $800, respectively.

The message claimed that the lease for software from the PC Cyborg Corporation had expired, and the user must pay to renew it. Once the files had been encrypted, the malware would then launch the ransom message. While the files themselves were not affected, the encryption would alter the extension names and prevent them from being executable. After a certain number of times (typically 90, though it varied) the malware would trigger, encrypting the names of all the files within the C: drive using symmetrical encryption. While the virus did not affect the boot itself, it instead counted the number of times the file was executed. The operating system executed it with each boot.

AUTOEXEC.BAT was the startup file used for the Windows operating system at the time. Instead, it infected the C: drive of the computer and hijacked AUTOEXEC.BAT in the root directory. Once in the system, the malware did not encrypt the files immediately. One contained the “survey” while the other contained the installer for the malware. The disc contained two files, both written in QuickBASIC 3.0. In reality, the floppy disk would deliver its payload of encryption malware onto the computer, making it one of the earliest pieces of Trojan malware. The disc was stamped with a logo for the “PC Cyborg Corporation.” The software contained a questionnaire about the AIDS virus, disguising itself as a survey. Popp mailed every victim an infected floppy disc, labeled as “AIDS Information Introductory Diskette,” using hijacked mail subscriber lists to the World Health Organization AIDS conference and PC Business World magazine in December 1989. Popp’s malware was delivered in a fairly unorthodox manner, with the internet still being in its infancy. While the malware itself was weak, and easily removable with decryption software, the attack set the stage of over 20 years of ransomware and virus attacks, and highlighted the need for data security measures. Popp, an evolutionary biologist, to some 20,000 individuals and medical institutions. The first ransomware attack, launched in December 1989, was called PC Cyborg, or AIDS Trojan.
