1989: First denial of service (DoS) attack
Robert Morris creates a worm computer to highlight security vulnerabilities such as Sendmail Unix and weak passwords. However, even though the goal was not to cause major problems, the code was written in such a way that the worm over-replicated causing damage estimated at between $ 100,000 and $ 10,000,000.
