The Notorious Creeper Virus: A Precursor To Modern Malware

01 Aug, 2025

What is a creeper virus? It is a self-replicating program that can spread from one computer to another over a network.

The Creeper virus was the first known computer virus. It was created in 1971 by Bob Thomas, an engineer at BBN Technologies. The virus was designed to spread through the ARPANET, the precursor to the modern Internet. Creeper would infect a computer and display the message "I'm the creeper, catch me if you can!" The virus would then attempt to spread to other computers on the network.

Creeper was not a malicious virus. It did not damage files or steal information. However, it was still a nuisance, and it showed the potential for viruses to spread through networks. Creeper also led to the development of the first antivirus program, Reaper, which was created to delete Creeper from infected computers.
