Marcus Hutchins, also known online as MalwareTech, is a British computer security researcher known for temporarily stopping the WannaCry ransomware attack. He is employed by cybersecurity firm Kryptos Logic.
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, but included the allegations that he created the Kronos malware in 2014, and sold it in 2015 via the AlphaBay forums. Hutchins denied any wrongdoing and pleaded not guilty to the charges against him on August 2017. He is out on bail pending trial and remains in Los Angeles. In early June 2018, the U.S. government added four more charges to his indictment.
On April 19, 2019, Hutchins plead guilty to conspiring to commit wire fraud, as well as distributing, selling, promoting, and advertising a device used to intercept electronic communications. His statement included the quote "I regret these actions and accept full responsibility for my mistakes. Having grown up, I’ve since been using the same skills that I misused several years ago for constructive purposes". Hutchins faces up to five years in prison and $250,000 in fines for two charges related writing malware in the years prior to his career in security.
