Marcus Hutchins, also known as @malwaretechblog, a young cyber expert, who stopped the WannaCry cyber-attack earlier this year was arrested in Las Vegas for “his role in creating and distributing the Kronos banking Trojan,” according to a spokesperson from the U.S. Department of Justice.
The trojan stole credentials and personal information and put malicious code on victims’ computers.
An indictment released by the US Department of Justice revealed that he faces six counts of helping to create, spread and maintain the banking Trojan Kronos between 2014 and 2015.
Hutchins was jointly charged with another individual who was not named.
The indictment alleged that Hutchins “created the Kronos malware” and the other person later sold it for $2,000 online.
Earlier this year, Hutchins became a hero when he discovered a kill switch for the WannaCry ransomware attack which spread malicious software to about 300,000 computers across 150 countries. The ransomware locked down computers and demanded $300 to get files back. The U.K.’s National Health Service, FedEx Corp., Nissan Motor Co. and Renault were among entities impacted.
