U.S. and Canadian authorities arrested and charged a Canadian man with operating the KimWolf distributed denial-of-service (DDoS) botnet, which infected nearly two million devices worldwide.

23-year-old Jacob Butler (also known online as "Dort") was arrested by Canadian authorities in Ottawa on Wednesday pursuant to an extradition warrant.

According to a criminal complaint unsealed on Thursday in the District of Alaska, Butler was taken into custody based on IP address and online account information, transaction records, and online messaging records that exposed his links to the KimWolf botnet.

Butler now awaits extradition to the U.S. and is facing one count of aiding and abetting computer intrusions, which carries a maximum sentence of 10 years in prison.

As detailed in court documents, KimWolf operated as a DDoS-for-hire service and was used by cybercriminals to launch attacks reaching nearly 30 terabits per second, the largest DDoS attack publicly disclosed at the time.
