Marcus Hutchins, also known online as MalwareTech, is a British computer security researcher known for temporarily stopping the WannaCry ransomware attack.[1][2] He is employed by cybersecurity firm Kryptos Logic.[3][4]

In August 2017, Hutchins was arrested in Las Vegas (where he was attending the DEF CON conference) after being indicted on six hacking-related federal charges in the U.S. District Court for the Eastern District of Wisconsin. Prosecutors allege that Hutchins assisted in the creation and spread of a piece of banking malware known as Kronos in 2014 and 2015. The charges are not related to WannaCry,[5][6] but included the allegations that he created the Kronos malware in 2014, and sold it in 2015 via the AlphaBay forums.[7][8] Hutchins denied any wrongdoing and pleaded not guilty to the charges against him on August 2017.[9] He is out on bail pending trial and remains in Los Angeles.[10] In early June 2018, the U.S. government added four more charges to his indictment.[11]

Hutchins is from Ilfracombe, Devon, UK.[12]
