who created wannacry

[70] 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. [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. As of a couple of days ago, those who created WannaCry have collected about $70,000 in ransom payments. According to him and others "they could have done something ages ago to get this problem fixed, and they didn't do it". Headed for the laundry. 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 DOJ indictment breaks down several of these connections in their indictment. Only a few months earlier, the British cyber security researcher had been named as the hero who foiled a major ransomware attack. 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. [26], The attack began on Friday, 12 May 2017,[32][33] with evidence pointing to an initial infection in Asia at 07:44 UTC. [54] Later globally dispersed security researchers collaborated online to develop open source tools[173][174] that allow for decryption without payment under some circumstances. 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. EPA/Ritchie B. Tongo. [38] Those still running unsupported versions of Microsoft Windows, such as Windows XP and Windows Server 2003[39][40] 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. WannaCry is a ransomware cryptoworm cyber attack that targets computers running the Microsoft Windows operating system. [11] It is considered a network worm because it also includes a "transport" mechanism to automatically spread itself. This has also happened in 2019. 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. [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. But you have not so enough time." User’s files were held hostage, and a Bitcoin ransom was demanded for their return. "[165][166][167] Russian President Vladimir Putin placed the responsibility of the attack on U.S. intelligence services, for having created EternalBlue. An example: Both a WannaCry sample and Trojan.Alphanc used IP address 84.92.36.96 as a command-and-control IP address. 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. It's a wake-up call for companies to finally take IT security [seriously]". 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". He also said that despite obvious uses for such tools to spy on people of interest, they have a duty to protect their countries' citizens. WannaCry infected 200,00 computer systems in more than 150 countries. The worm is also known as WannaCrypt,[8] Wana Decrypt0r 2.0,[9] WanaCrypt0r 2.0,[10] and Wanna Decryptor. [88] Brad Smith, the president of Microsoft, said he believed North Korea was the originator of the WannaCry attack,[89] and the UK's National Cyber Security Centre reached the same conclusion. [64][65] A few days later, a new version of WannaCry was detected that lacked the kill switch altogether. [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. It was initially released on 12 May 2017. 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. The results were identical or near-identical. So how do the researchers know that the culprit or culprits speak Chinese? We see on a regular basis how attackers are finding new ways to compromise devices. [32] Within a day the code was reported to have infected more than 230,000 computers in over 150 countries. [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. [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. And so, a picture emerges of a hacker or hackers who speak Chinese as their native language and are fluent but not perfect in English as a second language. The ransomware encrypted data and demanded ransom of $300 to $600, paid in the cryptocurrency Bitcoin. The WannaCry ransomware attack was a global epidemic that took place in May 2017. In December 2017, the United States, United Kingdom and Australia formally asserted that North Korea was behind the attack. 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. [71], Separately, researchers from University College London and Boston University reported that their PayBreak system could defeat WannaCry and several other families of ransomware by recovering the keys used to encrypt the user's data. [36][37], Organizations that had not installed Microsoft's security update from April 2017 were affected by the attack. [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]”. [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. According to Kaspersky Lab, the four most affected countries were Russia, Ukraine, India and Taiwan.
