Marcus Hutchins, known as @MalwareTechBlog on Twitter, has been spared jail over malware charges.
British-born Hutchins, who was credited with creating a “kill switch” for WannaCry, was arrested in 2017 in Las Vegas after attending DEF CON. He has remained in the US on bail ever since.
Back in April, he pleaded guilty to two charges of making malware, admitting to building two programs named Kronos and UPAS Kit.
US district judge Joseph Peter Stadtmueller said that the malware Hutchins helped stop was much more damaging than the two programs he created, and sentenced him to time served with a year of supervised release.
After his sentencing Hutchins tweeted a message of thanks
Hutchins had faced a maximum sentence of 10 years in prison. He is now free to return to the UK.
