Marcus Hutchins, a security researcher who gained worldwide notoriety for helping stop the disruptive and viral WannaCry malware, was sentenced to time served and supervised release on Friday, according to reporters who were present at the hearing.

The researcher, also known as MalwareTech, plead guilty to two counts of hacking in April for his role in the making of the Kronos banking malware when he was a teenager.

The two counts of hacking crimes Hutchins pleaded guilty to each carried a maximum sentence of 5 years in prison, $250,000 in fines, and up to 1 year of supervised release. The judge weighed his role in stopping WannaCry, as well as the prosecutor’s failure to show how much damage Kronos actually made, in giving Hutchins a lower sentence.

After Hutchins’ guilty plea, The New York Times’ Sarah Jeong argued that the researcher deserved a pardon, given his contributions as a cybersecurity professional in the years after he was involved in creating Kronos.

With his sentence of time served, Hutchins will not spend any time in prison; he has spent the majority of his time since being arrested in Los Angeles with an ankle monitor.
