Ransomware cyber attacks hit companies and government organisations across the globe at the end of last week.
The attacks first hit NHS hospitals across Britain, where a virus encrypted computers files, followed by a demand to de-code them, with payment in bitcoin.
Russia, Ukraine, and Taiwan were the worst hit by the attacks. In Russia, there were unconfirmed reports the attacks had hit police computers in several regions and two of the country’s biggest mobile phone and electronics retailers.
By mid afternoon on Friday, 36,000 attacks of the malware, called WannaCry or WannaCry 2,had been recorded around the globe. Malware security companies detected attacks in Spain, the Philippines, and Kazakhstan, Turkey, Vietnam, Germany, Indonesia, and Japan.
MalwareTech, a company that tracks cyber attacks, said its Botnet Tracking Servers had picked up over 38,000 attacks in dozens of countries around the world, with Europe, the United States, and China heavily affected.
The ransomware hit Telefónica, Spain’s leading telecom company, around midday on Friday, causing operators’ computer screens to turn blue.
Access to files became impossible and a demand for a ransom of $300 to be paid in bitcoins flashed up on screens at Telefónica’s headquarters in northern Madrid. The message said the amount would increase after May 15 and a few days later the files destroyed.
22 year old, Marcus Hutchins, a self-taught cyber expert from Devon, managed to stop the malware attack from spreading further by accidentally triggering a ‘kill switch’.
Hutchins, who works from his bedroom at his parents’ home, took just a few hours to take down the virus. He did this by purchasing a web domain for £8 and re-directing it elsewhere.
He is now working with the government’s National Cyber Security Centre to prevent a new strain of the malicious software.
