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 DOJ indictment breaks down several of these connections in their indictment. It's a wake-up call for companies to finally take IT security [seriously]". [23][27] Three hardcoded bitcoin addresses, or "wallets", are used to receive the payments of victims. Activating this kill-switch led to a rapid decline in attacks. [169], On 15 June 2017, the United States Congress was to hold a hearing on the attack. This ransomware attack spread through computers operating Microsoft Windows. [48], The day after the initial attack in May, Microsoft released out-of-band security updates for end of life products Windows XP, Windows Server 2003 and Windows 8; these patches had been created in February of that year following a tip off about the vulnerability in January of that year. WannaCry hero, Marcus Hutchins, pleads guilty to creating and distributing banking malware and reignites the debate about the role of black hat hackers in the cybersecurity industry. [163] British cybersecurity expert Graham Cluley also sees "some culpability on the part of the U.S. intelligence services". [112][113][114], The attack's impact is said to be relatively low compared to other potential attacks of the same type and could have been much worse had Marcus Hutchins not discovered that a kill-switch had been built in by its creators[115][116] or if it had been specifically targeted on highly critical infrastructure, like nuclear power plants, dams or railway systems. This was followed by a second variant with the third and last kill-switch on 15 May, which was registered by Check Point threat intelligence analysts. [50] The head of Microsoft's Cyber Defense Operations Center, Adrienne Hall, said that “Due to the elevated risk for destructive cyber-attacks at this time, we made the decision to take this action because applying these updates provides further protection against potential attacks with characteristics similar to WannaCrypt [alternative name to WannaCry]”. According to him and others "they could have done something ages ago to get this problem fixed, and they didn't do it". [95], North Korea, however, denied being responsible for the cyberattack. [78], Within four days of the initial outbreak, new infections had slowed to a trickle due to these responses. WannaCry ransomware hero won't go to prison for creating banking malware . [79], Linguistic analysis of the ransom notes indicated the authors were likely fluent in Chinese and proficient in English, as the versions of the notes in those languages were probably human-written while the rest seemed to be machine-translated.

EternalBlue is a cyberattack exploit developed by the U.S. National Security Agency (NSA). When executed, the WannaCry malware first checks the "kill switch" domain name; if it is not found, then the ransomware encrypts the computer's data,[22][23][24] then attempts to exploit the SMB vulnerability to spread out to random computers on the Internet,[25] and "laterally" to computers on the same network.

May 15, 2017, 6:13 PM • 5 min read. [64][65] A few days later, a new version of WannaCry was detected that lacked the kill switch altogether. It is based on evidence. "[92] In a press conference the following day, Bossert said that the evidence indicates that Kim Jong-un had given the order to launch the malware attack. [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. The researchers further determined that it was the English version of the ransom note that was used with Google Translate to create all the other versions using a simple test: They put the English version of the note through Google Translate themselves, and compared the results to the 25 other versions of the note.
