According to Europol, the WannaCry cyber attack infected 230 000 computer systems across 150 countries in 48 hours. WannaCry encrypted information on computers and asked users to pay $300 in exchange for decryption. The hackers took advantage of a known flaw in Windows XP. Britain’s National Health Service (NHS) was also affected, the virus caused ambulances to be diverted and non-emergency services to shut down. (https://econ.st/2DGTCdb, http://bit.ly/2RTFhxd)
