On November 3, 1988, 25 years ago this Sunday, people woke up to find the Internet had changed forever. The night before, someone had released a malevolent computer program on the fledgling computer network. By morning, thousands of computers had become clogged with numerous copies of a computer “worm,” a program that spread from computer to computer much like a biological infection.
Robert Morris’ father worked for the NSA at the time.
There is a description of Morris in Clifford Stoll‘s book The Cuckoo’s Egg. Many readers of Stoll’s book remember Morris for giving Stoll a challenging mathematical puzzle (originally due to John H. Conway) in the course of their discussions on computer security: What is the next number in the sequence 1 11 21 1211 111221? (known as the look-and-say sequence). Stoll chose not to include the answer to this puzzle in The Cuckoo’s Egg, to the frustration of many readers.
