HyperCard viruses

Computer viruses that target HyperCard

Soon after the release of HyperCard in 1987, computer viruses appeared that targeted the application.[1] The viruses were written in the HyperTalk programming language and typically spread by infecting the Home stack and then infecting other stacks from there.[2][3]
