After 20 years of prominence, distributed denial-of-service (DDoS) attacks may be causing more devastating effects than ever. The first DDoS attack occurred way back on July 22, 1999 when a network of 114 computers infected with a malicious script called Trin00 attacked a computer at the University of Minnesota, according to MIT Technology Review. The infected computers overwhelmed the university computer with bogus data packets, preventing it from handling legitimate requests.
The attack continued for two days and introduced a tactic that has been interrupting business services and websites ever since.
