The cyber security expert who stopped the WannaCry ransomware attack has appeared in court over allegations he created malware against bank customers.
Marcus Hutchins, also known as MalwareTech, was widely praised when he stopped the ransomware attack which hit the NHS earlier this year, but he was arrested earlier this month in Las Vegas.
It is claimed that he created malware in 2014 and 2015 which could gain the log-in details of online banking customers.
Charges include creating the malware, which is named Kronos, and conspiring to sell it to cyber criminals.
However he denied all charges when appearing at a federal court in Milwaukee today, according to Journal Sentinel.
As the case continues, Hutchins has been given the right to both live and work in Los Angeles. He had been released last week on $30,000 (£23,100) bail and put in a Nevada half-way house.
He has also had to give up his passport. Another defendant is also involved in the case but has not yet been named.
It is thought the other defendant could be someone who lives in Wisconsin as that was where the case was investigated.
They have been charged with appearing on a YouTube video explaining how to use Kronos, advertising the malware and making one sale for $2,000 (£1,540) in digital currency.
