List of HyperCard viruses
(Redirected from HyperCard viruses)
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]
List of viruses
[edit]| Name of Virus | Year discovered | Notes |
|---|---|---|
| Dukakis | 1988 | First known HyperCard virus.[1][4] Self-destructs after displaying a message encouraging people to vote for Michael Dukakis.[1][3] |
| 3 Tunes (or HC) | 1991[4] | First reported from Holland and Belgium.[4] On systems running the German Mac OS, the virus causes infected stacks to play three German folk tunes.[3] |
| MerryXmas | 1991[5] | Intended to simply propagate, but because of an error, the virus sometimes copies parts of other stack scripts along with its own code causing stacks to behave unexpectedly. Variants include Merry2Xmas, Lopez, and Crudshot.[3] |
| HC 9507 | 1995 | Causes the word "Pickle" to be typed at the cursor insertion point. May also cause the computer to crash.[3][6] |
| Antibody | 1997 | Eradicates the MerryXmas virus and installs MerryXmas inoculation code into infected stacks.[3] |
| Independance Day | 1997 | After July 4, 1997, unsuccessfully attempts to delete random lines of code from stacks.[3] |
| Blink | 1998 | After January 1, 1999, causes infected stacks to blink.[3] |
| Wormcode | 2000 | Originally posted to the usenet group "comp.sys.mac.hypercard" in a stack called "Font Preview". Aside from spreading, the virus does no damage.[3] |
