In May, Marcus Hutchins – aka Malware Tech – became a national hero after “accidentally” discovering a killswitch for the WannaCry virus that had paralysed parts of the NHS.
Now, the 23-year-old darling of cyber security is facing charges of cyber crime following a turn of events that have sent shockwaves through the industry.
So what do we know about his indictment?
Hutchins, from Ilfracombe in Devon, was reportedly arrested by the FBI in Las Vegas on Wednesday before he was due to travel back from cyber security conferences Black Hat and Def Con.
He is set to appear in court in Las Vegas later today accused of involvement with a piece of malware used to access people’s bank accounts.
“Marcus Hutchins… a citizen and resident of the United Kingdom, was arrested in the United States on 2 August, 2017, in Las Vegas, Nevada, after a grand jury in the Eastern District of Wisconsin returned a six-count indictment against Hutchins for his role in creating and distributing the Kronos banking Trojan,” said the US Department of Justice.
“The charges against Hutchins, and for which he was arrested, relate to alleged conduct that occurred between in or around July 2014 and July 2015.”
His court appearance comes after he was arraigned in Las Vegas yesterday. He made no statement beyond a series of one-word answers to basic questions from the judge, the Guardian reports. A public defender said Hutchins had no criminal history and had previously cooperated with federal authorities.
Kronos, a so-called Trojan, is a kind of malware that disguises itself as legitimate software while harvesting unsuspecting victims’ banking login details and other financial data.
It emerged in July 2014 on a Russian underground forum, where it was advertised for $7,000 (£5,330), a relatively high figure at the time, according to the BBC.
Shortly after it made the news, a video demonstrating the malware was posted to YouTube allegedly by Hutchins’ co-defendant, who has not been named. Hutchins later tweeted: “Anyone got a kronos sample?”
His mum, Janet Hutchins, told the Press Association it is “hugely unlikely” he was involved because he spent “enormous amounts of time” fighting attacks.
Meanwhile Ryan Kalember, a security researcher from Proofpoint, told the Guardian that the actions of researchers investigating malware may sometimes look criminal.
The indictment alleges that Hutchins created and sold Kronos on internet forums including the AlphaBay dark web market, which has recently been shut down.
“This could very easily be the FBI mistaking legitimate research activity with being in control of Kronos infrastructure,” said Kalember. “Lots of researchers like to log in to crimeware tools and interfaces and play around.”
“Sometimes you have to at least pretend to be selling something interesting to get people to trust you”, he added. “It’s not an uncommon thing for researchers to do and I don’t know if the FBI could tell the difference.”
It’s a sentiment echoed by US cyber-attorney Tor Ekeland, who told Radio 4’s Today Programme: “I can think of a number of examples of legitimate software that would potentially be a felony under this theory of prosecution.”
Hutchins could face 40 years in jail if found guilty, Ekelend said, but he added that no victims had been named.
