The world has come a long way since the first computer viruses — Creeper, Wabbit and Elk Cloner — were unleashed on the ARPANET (forming the technical base of today’s internet) close to half a century ago. Initially self-replicating and somewhat harmless programmes, these viruses and worms gradually turned complex, vicious and persistent. The internet is a goldmine for cybercriminals and they can easily release malware for a price, bringing businesses as well as nations to a crashing halt.
Millions of systems have been compromised worldwide over the years as cybercriminals stole money, credentials and information, or just caused intense turmoil.
