In keeping with our 8-bit theme, on Wednesdays we will celebrate #WayBackWednesday. On these days, we will look back into cyber security history at some key moments and memories.
We’ll start our journey into the past with “Creeper” and “Reaper”.
When you think of “Creeper”, your mind might flash to scenes of Minecraft. And, with “Reaper”, your thoughts may leap to scary movies with figures in dark cloaks. But, that’s not 8-bit cyber history…
In 1971, Bob Thomas wrote a computer program called “Creeper”. It moved from one DEC PDP-10 mainframe to another over ARPANET. Later, Ray Thomlinson adjusted the program so that copies of itself remained on each host. When the program ran, it printed to the terminal, “I’M THE CREEPER : CATCH ME IF YOU CAN”.
Although the program was a proof of concept and not malicious, it is commonly known as the first computer worm.
To clean up the problem, Ray Thomlinson then wrote the “Reaper” program. Reaper searched through ARPANET for infected mainframes and removed the Creeper program.
