Sharing the lessons of malware

摘要

Worldwide cyber attacks in May paralysed parts of one of the UK's best-loved institutions - the NHS, including the hospitals trust here in Lincolnshire. Immediately, as the scale and method of attack were unknown, the council disconnected from N3, the national NHS network, as well as urging staff to be extra vigilant when opening emails, visiting websites and using removable media. Although this authority remained largely unaffected, the WannaCry ransomware attack brought back vivid memories of being in the frontline against the hackers last year. So what exactly happened when Lincolnshire CC fell victim to a malware assault on 26 January 2016? And what lessons have we learned that we can pass on to others?
