Creeper (program)
| Type | Worm[1] |
|---|---|
| Isolation | 1971 |
| Author(s) | Bob Thomas |
| Operating system(s) affected | TENEX |
Creeper was an experimental computer program written by Bob Thomas at BBN in 1971.[2] Its original iteration was designed to move between DEC PDP-10 mainframe computers running the TENEX operating system using the ARPANET, with a later version by Ray Tomlinson designed to copy itself between computers rather than simply move.[3] This self-replicating version of Creeper is generally accepted to be the first computer worm.[1][4]
The program was not actively malicious software as it caused no damage to data, the only effect being a message outputted to the screen reading "I'm the creeper: catch me if you can".[4]

Reaper was a similar program created by Ray Tomlinson to move across the ARPANET and delete copies of the self-replicating Creeper.[3]
Cultural impacts
The conflict between Creeper and Reaper served as inspiration for the programming game Core War,[3] while fictionalized versions of Reaper have been used as antagonists in the anime Digimon Tamers and the visual novel Digital: A Love Story.
