On a single day last May, a massive cyber-attack called WannaCry Ransomware blighted over 200,000 Windows computers in some 150 countries. It might have been more had it not been for the quick actions of Marcus Hutchins, a cyber-security expert, who discovered a kill-switch built into the ransomware’s code. Apparently, before infecting a system, locking its files, and demanding a ransom from its owner, the ransomware first checked for the non-existence of a gobbledygook web domain. Hutchins simply registered the domain for $10, brought it into existence by pointing URL requests to his own server, and thereby thwarted the attack. Hutchins became an overnight hero (sadly for him, the new status did not last much longer than overnight). However, you or I could have claimed some credit for halting WannaCry. All we would have needed was Hutchins in our team, and set him to work. Failing that, we would have to have had at least one person in our team capable of coming up with the idea of looking for a kill switch, another able to find it hidden in the code, and another with a credit card to put in a call to GoDaddy.
