Security companies and law enforcement have so far been unable to identify the hackers, or even what country they're in. It was initially released on 12 May 2017. WannaCry created and distributed a ransomware worm that infected over 250,000 systems globally. [184], After the attack, NHS Digital refused to finance the estimated £1 billion to meet the Cyber Essentials Plus standard, an information security certification organized by the UK NCSC, saying this would not constitute "value for money", and that it had invested over £60 million and planned "to spend a further £150 [million] over the next two years" to address key cyber security weaknesses. [8] A Kaspersky Lab study reported however, that less than 0.1 percent of the affected computers were running Windows XP, and that 98 percent of the affected computers were running Windows 7. [13] Metadata in the language files also indicated that the computers that created the ransomware were set to UTC+09:00, used in Korea. [14][15] Microsoft eventually discovered the vulnerability, and on Tuesday, 14 March 2017, they issued security bulletin MS17-010, which detailed the flaw and announced that patches had been released for all Windows versions that were currently supported at that time, these being Windows Vista, Windows 7, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2016.[16]. [42][43][44], Experts quickly advised affected users against paying the ransom due to no reports of people getting their data back after payment and as high revenues would encourage more of such campaigns. Starting from 21 April 2017, security researchers reported that there were tens of thousands of computers with the DoublePulsar backdoor installed. Headed for the laundry.

[66][67][68][69], On 19 May, it was reported that hackers were trying to use a Mirai botnet variant to effect a distributed attack on WannaCry's kill-switch domain with the intention of knocking it offline. May 15, 2017, 6:13 PM • 5 min read. [104] On 12 May, some NHS services had to turn away non-critical emergencies, and some ambulances were diverted. [7], WannaCry is a ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. The WannaCry ransomware is composed of multiple components. [169], On 15 June 2017, the United States Congress was to hold a hearing on the attack. Known as WannaCry, this strain of ransomware was developed by as-yet unknown hackers using tools first developed by the NSA and affects some computers running Microsoft software. Security experts believed from preliminary evaluation of the worm that the attack originated from North Korea or agencies working for the country. WannaCry is also known as WannaCrypt, WCry, Wana Decrypt0r 2.0, WanaCrypt0r 2.0 and Wanna Decryptor. It's called the eternal blue. The key is kept in the memory if the WannaCry process has not been killed and the computer has not been rebooted after being infected. Edward Snowden said that if the NSA had "privately disclosed the flaw used to attack hospitals when they found it, not when they lost it, the attack may not have happened". [citation needed], Screenshot of the ransom note left on an infected system, CS1 maint: multiple names: authors list (, Taiwan Semiconductor Manufacturing Company, Guilin University of Aerospace Technology, Guilin University of Electronic Technology, Ministry of Internal Affairs of the Russian Federation, International Multilateral Partnership Against Cyber Threats, "The WannaCry ransomware attack was temporarily halted. [55][56][57] Registering a domain name for a DNS sinkhole stopped the attack spreading as a worm, because the ransomware only encrypted the computer's files if it was unable to connect to that domain, which all computers infected with WannaCry before the website's registration had been unable to do. Activating this kill-switch led to a rapid decline in attacks. Organizations infected with WannaCry have little recourse but to either pay the ransom or wipe infected systems and restore encrypted data from backups (if they have any). The results were identical or near-identical. Tech Reporter.
