After being nabbed by the FBI while leaving DefCon, the security researcher who singlehandedly neutralized the WannaCry malware attack earlier this year is back online. Marcus Hutchins, a.k.a. @malwaretech, appeared for his arraignment at a federal court in Wisconsin on Monday where he entered a not guilty plea and successfully argued that he should be allowed internet access. Hutchins faces six charges related to his alleged involvement in the Kronos banking malware in 2014.

Initially, Hutchins was prevented from going online after his arrest. In court today, Hutchins was granted nearly unfettered access to the internet, with the only stipulation being that he not access the “sinkhole” he created that stopped WannaCry. Naturally, he tweeted for the first time since his arrest, addressing his case and thanking his many supporters.
