Sujet 5 - Joker - WannaCry

jeudi 22 mars 2018


On 12 May 2017, a massive ransomware attack occurred across a wide range of sectors, including health care, government, telecommunications and gas. To date, WannaCry has spread to over 300,000 systems in over 150 countries. The countries that appear to be the most affected are Russia and China, probably because of the high percentage of legacy software, with significant impacts elsewhere, notably to the UK National Health Service. The spread of the ransomware reportedly slowed in the two days following the launch of the attack, in part due to the discovery of a “kill switch” in its code. However, there are reports of new variants of the malware (such as Uiwix) which do not have this kill switch. Data on new variants is unconfirmed and limited at the moment, and EY wil publish updates as more information becomes available.
