Registering a single web address may have stopped a global malware attack
Over the past 24 hours, a ransomware program called WannaCry has shut down more than 75,000 computers across 99 countries, including a string of hospitals in the United Kingdom and critical gas and water utilities in Spain. But despite the massive scale of the attack, stopping new infections from the attack seems to have been as simple as registering a single web address.
This morning, researchers announced they had found a kill switch in the code of the ransomware program — a single domain which, when registered, would prevent any infections from taking place. It’s still unclear whether registering that domain will stop every strain of the infection, but it should severely limit the global spread of the attack.
