The historical backdrop of cybersecurity started with a research
venture. A man named Bob Thomas understood that it was feasible for
a computer program to move over a system, leaving a little trail
wherever it went. He named the program Creeper, and structured it
to travel through Tenex terminals on the ARPANET, and thus printing
the message as "I am the Creeper, catch me if you
can."
A man named Ray Tomlinson (the same person who evolved email)
saw this thought and liked it. He amended the program and made it
self-recreating—the primary PC worm. At that point, he
composed another program—Reaper, the first
antivirus programming—which would pursue Creeper and erase
it.
It's funny to think again from where we are presently, in a
time of ransomware, fileless malware, and country state assaults,
and understand that the predecessors to this issue were less unsafe
than today. And we have so evolved from there to here.
