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. , 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.  In 2016, thousands of computers in 42 separate NHS trusts in England were reported to be still running Windows XP. , The ransomware campaign was unprecedented in scale according to Europol, which estimates that around 200,000 computers were infected across 150 countries. , 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.

It was initially released on 12 May 2017. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end-of-life. Some early researchers noted coding similarities between WannaCry and North Korea's "Lazarus Group" of hackers but since any programmer can re-use source code, that doesn't pin things down very much. The man who stopped the recent global cyberattack known as WannaCry has been arrested for allegedly creating a virus of his own that aimed to steal peoples’ banking details online. Even if cybersecurity isn't your area, you likely know that over the past two weeks a nasty bit of ransomware named WannaCry created havoc for companies, universities, and even hospitals around the world. Ransomeware, of course, only works if the people whose computers are attacked can read and obey the instructions for sending money to the hackers, and so WannaCry's ransom note appeared on computers in a total of 28 different languages. At least, the EternalBlue exploit was. 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.  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]”. This ransomware attack spread through computers operating Microsoft Windows. The attack was estimated to have affected more than 200,000 computers across 150 countries, with total damages ranging from hundreds of millions to billions of dollars. , It was discovered that Windows encryption APIs used by WannaCry may not completely clear the prime numbers used to generate the payload's private keys from the memory, making it potentially possible to retrieve the required key if they had not yet been overwritten or cleared from resident memory.  Organizations were advised to patch Windows and plug the vulnerability in order to protect themselves from the cyber attack. But now, researchers at the security firm Flashpoint have conducted extensive analysis on the ransomware, using human languages instead of computer languages, and they've pinned down the likely nationality of the hacker or hackers who created WannaCry. The hack appears to have originally been discovered by the NSA, which allegedly kept it on file as a potential tool to use for surveillance or other issues. John Miller, expert in cybersecurity from FireEye, has said that the similarities in code between the WannaCry virus and the virus created the Lazarus Group are not sufficient to prove that the viruses have a common source. , The NHS denied that it was still using XP, claiming only 4.7% of devices within the organization ran Windows XP.  Snowden states that when "NSA-enabled ransomware eats the Internet, help comes from researchers, not spy agencies" and asks why this is the case. Security companies and law enforcement have so far been unable to identify the hackers, or even what country they're in. Linguistic analysis by security firm Flashpoint reveals clues to the hackers' whereabouts.  On 12 May, some NHS services had to turn away non-critical emergencies, and some ambulances were diverted. Tech Reporter. 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". , EternalBlue is an exploit of Windows' Server Message Block (SMB) protocol released by The Shadow Brokers.  Within a day the code was reported to have infected more than 230,000 computers in over 150 countries. But Flashpoint researchers think they may know even more. An example: Both a WannaCry sample and Trojan.Alphanc used IP address 18.104.22.168 as a command-and-control IP address.  Three hardcoded bitcoin addresses, or "wallets", are used to receive the payments of victims. With security firms alerted and Microsoft rushing to provide a patch (Wannacry exploits a vulnerability in the Windows operating system), the attack seems to be waning for now. The National Security Agency has linked the North Korean government to the creation of the WannaCry computer worm that affected more than …  British cybersecurity expert Graham Cluley also sees "some culpability on the part of the U.S. intelligence services". The original WannaCry ransomware — version 2.0, to be more accurate, and also known as WCry, WannaCrypt, Wana Decrypt0r, and WanaCrypt0r — appeared on Friday and it … Who created WannaCry?  It is considered a network worm because it also includes a "transport" mechanism to automatically spread itself. DoublePulsar is a backdoor tool, also released by The Shadow Brokers on 14 April 2017.  According to an analysis by the FBI's Cyber Behavioral Analysis Center, the computer that created the ransomware language files had Hangul language fonts installed, as evidenced by the presence of the "\fcharset129" Rich Text Format tag. , 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. WannaCry ransomware hero won't go to prison for creating banking malware . , Marcus Hutchins, a cybersecurity researcher, working in loose collaboration with UK's National Cyber Security Centre, researched the malware and discovered a "kill switch". Security experts believed from preliminary evaluation of the worm that the attack originated from North Korea or agencies working for the country. As with all such wallets, their transactions and balances are publicly accessible even though the cryptocurrency wallet owners remain unknown.

This could also be either simple re-use of code by another group or an attempt to shift blame—as in a cyber false flag operation; but a leaked internal NSA memo is alleged to have also linked the creation of the worm to North Korea. , 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.

WannaCry is also known as WannaCrypt, WCry, Wana Decrypt0r 2.0, WanaCrypt0r 2.0 and Wanna Decryptor.  Brad Smith, the president of Microsoft, said he believed North Korea was the originator of the WannaCry attack, and the UK's National Cyber Security Centre reached the same conclusion. 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. By Keith Collins. , 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. , 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. Amazing story", "Pause a moment to consider why we're left with researchers, not governments, trying to counter the @NSAGov-enabled ransomware mess. The worm is also known as WannaCrypt, Wana Decrypt0r 2.0, WanaCrypt0r 2.0, and Wanna Decryptor. EPA/Ritchie B. Tongo.  This approach was iterated upon by a second tool known as Wanakiwi, which was tested to work on Windows 7 and Server 2008 R2 as well. " Russian President Vladimir Putin placed the responsibility of the attack on U.S. intelligence services, for having created EternalBlue.  Those still running unsupported versions of Microsoft Windows, such as Windows XP and Windows Server 2003 were at particularly high risk because no security patches had been released since April 2014 for Windows XP (with the exception of one emergency patch released in May 2014) and July 2015 for Windows Server 2003. Starting from 21 April 2017, security researchers reported that there were tens of thousands of computers with the DoublePulsar backdoor installed. , Several organizations released detailed technical writeups of the malware, including a senior security analyst at RiskSense, Microsoft, Cisco, Malwarebytes, Symantec and McAfee. , 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 or if it had been specifically targeted on highly critical infrastructure, like nuclear power plants, dams or railway systems.  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. But Flashpoint researchers announced, "Analysis revealed that nearly all of the ransom notes were translated using Google Translate and that only three, the English version and the Chinese versions (Simplified and Traditional), are likely to have been written by a human instead of machine translated." Even before wannacry was released Microsoft released a patch to solve this but we all know that many of us do not install patches…lol. Activating this kill-switch led to a rapid decline in attacks. WannaCry is also an eerie reminder of when the Stuxnet worm – a cyber weapon jointly created by the US and Israel to target Iranian nuclear facilities – …  The initial infection was likely through an exposed vulnerable SMB port, rather than email phishing as initially assumed.  Others have also commented that this attack shows that the practice of intelligence agencies to stockpile exploits for offensive purposes rather than disclosing them for defensive purposes may be problematic. The other '杀. This transport code scans for vulnerable systems, then uses the EternalBlueexploit to gain access… By Kevin Collier, CNN Business. Wanna Decryption, or WannaCry, is a ransomware that spread through Server Message Block (SMB) protocol, which is typically used by Windows machines to communicate with file systems over a network. WannaCry is a ransomware cryptoworm cyber attack that targets computers running the Microsoft Windows operating system. That’s not a large amount given the number of infected computers.  On 22 May, Hutchins protected the domain by switching to a cached version of the site, capable of dealing with much higher traffic loads than the live site.  Adam Segal, director of the digital and cyberspace policy program at the Council on Foreign Relations, stated that "the patching and updating systems are broken, basically, in the private sector and in government agencies". Much of the attention and comment around the event was occasioned by the fact that the U.S. National Security Agency (NSA) (from whom the exploit was likely stolen) had already discovered the vulnerability, but used it to create an exploit for its own offensive work, rather than report it to Microsoft. Shadow brokers, a hackers group created wannacry after they got this info.  By 25 April, reports estimated that the number of infected computers could be up to several hundred thousand, with numbers increasing every day. Headed for the laundry.  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. August 3, …  Spain's Telefónica, FedEx and Deutsche Bahn were hit, along with many other countries and companies worldwide. It's pretty clear that last sentence was never written by a native English speaker.  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. , One of the largest agencies struck by the attack was the National Health Service hospitals in England and Scotland, and up to 70,000 devices – including computers, MRI scanners, blood-storage refrigerators and theatre equipment – may have been affected. The U.S. National Security Agency (NSA) created it, and a hacking group called Shadow Brokers leaked it to the world. This has also happened in 2019. It also seems likely that a human rather than a piece of software translated the note from Chinese to English since using Google Translate for the job did not result in similar text to the English version of the note. The WannaCry ransomware is composed of multiple components. , 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. We see on a regular basis how attackers are finding new ways to compromise devices. "One term, '礼拜' for 'week,' is more common in South China, Hong Kong, Taiwan, and Singapore; although it is occasionally used in other regions of the country.  NHS hospitals in Wales and Northern Ireland were unaffected by the attack. Targets North Korean Hacking as National-Security Threat", "WannaCry: Are Your Security Tools Up to Date?

On 14 May, a first variant of WannaCry appeared with a new and second kill-switch registered by Matt Suiche on the same day.  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. So how do the researchers know that the culprit or culprits speak Chinese?  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. Who launched this computer worm into the world? , 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.
