[58][59][60][61][62] On 14 May, a first variant of WannaCry appeared with a new and second[63] kill-switch registered by Matt Suiche on the same day. These patches are imperative to an organization's cyber-security but many were not applied because of needing 24/7 operation, risking having applications that used to work break, inconvenience, or other reasons. [13] Metadata in the language files also indicated that the computers that created the ransomware were set to UTC+09:00, used in Korea. [51][52], Researcher Marcus Hutchins[53][54] discovered the kill switch domain hardcoded in the malware. [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. A human-style typo in the Chinese version makes it seem that it was drafted directly in that language rather than translated from another language. [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. [36][37], Organizations that had not installed Microsoft's security update from April 2017 were affected by the attack. [176][177][172], Other experts also used the publicity around the attack as a chance to reiterate the value and importance of having good, regular and secure backups, good cybersecurity including isolating critical systems, using appropriate software, and having the latest security patches installed. [169], On 15 June 2017, the United States Congress was to hold a hearing on the attack. Renault also stopped production at several sites in an attempt to stop the spread of the ransomware. [90], On 18 December 2017, the United States Government formally announced that it publicly considers North Korea to be the main culprit behind the WannaCry attack. [26], The attack began on Friday, 12 May 2017,[32][33] with evidence pointing to an initial infection in Asia at 07:44 UTC. But security experts warn that another, worse attack may be coming soon.

This transport code scans for vulnerable systems, then uses the EternalBlue exploit to gain access, and the DoublePulsar tool to install and execute a copy of itself. [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. Starting from 21 April 2017, security researchers reported that there were tens of thousands of computers with the DoublePulsar backdoor installed. The WannaCry ransomware attack was a May 2017 worldwide cyberattack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency.

[179], The effects of the attack also had political implications; in the United Kingdom, the impact on the National Health Service quickly became political, with claims that the effects were exacerbated by Government underfunding of the NHS; in particular, the NHS ceased its paid Custom Support arrangement to continue receiving support for unsupported Microsoft software used within the organization, including Windows XP. [186] The email threatened to destroy the victims' data unless they sent 0.1 BTC to the Bitcoin address of the hackers. [110][111] Spain's Telefónica, FedEx and Deutsche Bahn were hit, along with many other countries and companies worldwide. In August 2017, tired and in a haze from a week of parties at the annual Def-Con hacker conference, Marcus Hutchins was arrested at a Las Vegas airport. [12][20][21] On 9 May 2017, private cybersecurity company RiskSense released code on GitHub with the stated purpose of allowing legal “white hat” penetration testers to test the CVE-2017-0144 exploit on unpatched systems. [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. The attack was halted within a few days of its discovery due to emergency patches released by Microsoft and the discovery of a kill switch that prevented infected computers from spreading WannaCry further. It's called the eternal blue. That’s unfortunate. And then there's this: "We guarantee that you can recover all your files safely and easily. Updated 5:29 PM ET, Sat July 27, 2019 . [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]”. It is based on evidence. [8][41] In a controlled testing environment, the cybersecurity firm Kryptos Logic found that it was unable to infect a Windows XP system with WannaCry using just the exploits, as the payload failed to load, or caused the operating system to crash rather than actually execute and encrypt files. The WannaCry ransomware attack has quickly become the worst digital disaster to strike the internet in years, ... called EternalBlue, created the worst epidemic of malicious encryption yet seen. However, when executed manually, WannaCry could still operate on Windows XP. It's a wake-up call for companies to finally take IT security [seriously]". [180] Home Secretary Amber Rudd refused to say whether patient data had been backed up, and Shadow Health Secretary Jon Ashworth accused Health Secretary Jeremy Hunt of refusing to act on a critical note from Microsoft, the National Cyber Security Centre (NCSC) and the National Crime Agency that had been received two months previously. The worm is also known as WannaCrypt,[8] Wana Decrypt0r 2.0,[9] WanaCrypt0r 2.0,[10] and Wanna Decryptor. [170] Two subpanels of the House Science Committee were to hear the testimonies from various individuals working in the government and non-governmental sector about how the US can improve its protection mechanisms for its systems against similar attacks in the future. 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. [163] British cybersecurity expert Graham Cluley also sees "some culpability on the part of the U.S. intelligence services". [152], On 17 May 2017, United States bipartisan lawmakers introduced the PATCH Act[168] that aims to have exploits reviewed by an independent board to "balance the need to disclose vulnerabilities with other national security interests while increasing transparency and accountability to maintain public trust in the process". 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. FBI agents in Las Vegas have arrested Marcus Hutchins, the computer security expert who's been credited with stopping the WannaCry ransomware attack.

While this did not help already infected systems, it severely slowed the spread of the initial infection and gave time for defensive measures to be deployed worldwide, particularly in North America and Asia, which had not been attacked to the same extent as elsewhere. An example: Both a WannaCry sample and Trojan.Alphanc used IP address 84.92.36.96 as a command-and-control IP address. [54] Later globally dispersed security researchers collaborated online to develop open source tools[173][174] that allow for decryption without payment under some circumstances. WannaCry infected 200,00 computer systems in more than 150 countries. The WannaCry kill switch functionality was soon accidentally discovered by security researcher Marcus Hutchins, who on May 12, registered a domain found in the ransomware’s binary code. "The text uses certain terms that further narrow down a geographic location," they write. Security experts believed from preliminary evaluation of the worm that the attack originated from North Korea or agencies working for the country.

[116] Microsoft president and chief legal officer Brad Smith wrote, "Repeatedly, exploits in the hands of governments have leaked into the public domain and caused widespread damage. The weaponization—rather than responsible disclosure—of those underlying exploits created an opportunity for the WannaCry attack to be waged. User’s files were held hostage, and a Bitcoin ransom was demanded for their return. Who launched this computer worm into the world? [45][46][47] As of 14 June 2017, after the attack had subsided, a total of 327 payments totaling US$130,634.77 (51.62396539 XBT) had been transferred. [185], In late June, hundreds of computer users reported being sent an email from someone (or multiple people), claiming to be the developers of WannaCry. [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. EPA/Ritchie B. Tongo. The National Security Agency has linked the North Korean government to the creation of the WannaCry computer worm that affected more than … [109][105], Nissan Motor Manufacturing UK in Tyne and Wear, England, halted production after the ransomware infected some of their systems. [28], Several organizations released detailed technical writeups of the malware, including a senior security analyst at RiskSense,[29][30] Microsoft,[31] Cisco,[12] Malwarebytes,[25] Symantec and McAfee. [175] Snowden states that when "NSA-enabled ransomware eats the Internet, help comes from researchers, not spy agencies" and asks why this is the case. The worm is also known as WannaCrypt, Wana Decrypt0r 2.0, WanaCrypt0r 2.0, and Wanna Decryptor. According to him and others "they could have done something ages ago to get this problem fixed, and they didn't do it". The Department of Justice asserted this team also had been involved in the WannaCry attack, among other activities. [32][34] The initial infection was likely through an exposed vulnerable SMB port,[35] rather than email phishing as initially assumed. [101], One of the largest agencies struck by the attack was the National Health Service hospitals in England and Scotland,[102][103] and up to 70,000 devices – including computers, MRI scanners, blood-storage refrigerators and theatre equipment – may have been affected. It affected companies and individuals in more than 150 countries, including government agencies and multiple large organizations globally. At least, the EternalBlue exploit was. It was initially released on 12 May 2017. We see on a regular basis how attackers are finding new ways to compromise devices. This ransomware attack spread through computers operating Microsoft Windows. EternalBlue was stolen and leaked by a group called The Shadow Brokers at least a year prior to the attack. WannaCry wreaked massive havoc like a cyberweapon, and there’s a reason for that – because it was actually developed as a cyberweapon! 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".
