MILWAUKEE, WI. – Marcus Hutchins, the malware researcher who became known as a "coincidence hero" to stop the WannaCry ransomware attack in 2017, is sentenced to a one-year charge on guarded release to create and sell Kronos bank malware.
Presiding Judge JP Stadmueller described Hutchins, 25, as a "talented" but "youthful insult" in court remarks on Friday.
The judge said that Hutchins' time had been served and will not face any time in prison.
"It's going to take people like [Hutchins] with your skills to come up with solutions because that's the only way we're going to eliminate the whole topic of the sadly inadequate security protocols," Stadmueller said.
The judge said he was looking at Hutchins' age at the time of the offense, and gave him the credit for "turning a corner" into his life before being accused.
Stadmueller said, however, that his judgment is likely to prevent him from returning to the United States.
In a statement, Hutchins said he took some "bad decisions" as a teenager. "I deeply regret my behavior and the damage that was caused," he said.
"I have no desire to return to that life," he said and apologized to the victims of malicious software he created.
Hutchins, a British citizen who goes online @MalwareTech was arrested in Las Vegas by federal marshals in August 201
Since the indictment he had lived in Los Angeles.
Hutchins first refused to create malicious software. However, after the prosecuting authorities filed a replacement, he later accused the two main counts of creating and selling malicious software. Eight remaining charges were dropped following his change in prayer.
The prosecuting authorities said that Hutchins faced 10 years' imprisonment and a $ 500,000 fine.
In a statement according to his guilty claim, he said he regretted his actions and accepted "full responsibility for my mistakes."  The prosecutors said that even though Hutchins and an accomplice had only generated a few thousand dollars from selling malicious software, Kronos allowed others to take advantage of financial use of malware.
Hutchins & # 39; indictment came four months after he was hailed as a hero for registering a domain name that stopped the spread of WannCry cyber attack, which beat tens of thousands of computers offline with ransomware in a matter of hours.
The Ransomware attack, later blamed on North Korean hackers, spread across Ukraine, Europe and the United Kingdom, encryption systems and banks businesses and government departments offline The UK National Health Service The NHS was one of the largest organizations affected, and Caught doctors to turn patients away and medical attention to shut down. Hutchins, who at the time of the attack for Los Angeles-based Cryptos Logic from his home in the South of England, registered the domain in an attempt to understand why ransomware spread. Later it was shown that the domain acts as a "kill switch" and stopped it dead in the tracks.
The week after, kill switch was the target of powerful botnets hoping to turn the domain offline and a new outbreak.  Hutchins told TechCrunch last month that the WannaCry attack was one of the most stressful and exhausting moments in his life.
However, since the attack, Hutchins received an additional recognition for its harmful research on new infections and bone remedies. He has been praised for having flocked directly to his work so others can learn how to transform malware. Many in the security community – and beyond – have asked the court to give Hutchins grace for his recent concerted efforts to protect users from security threats.
The prosecutors acknowledged Hutchins' reformed character in a criminal document filed this week, and said Hutchins has "taken a good decision to make the talents more positive."
When it was reached, a spokesman for the Justice Department commented on the US law office for the Eastern District of Wisconsin, which did not immediately comment.
