CANADIAN authorities arrested Jacob Butler, a 23-year-old from Ottawa, for allegedly operating the Kimwolf DDoS botnet, which enslaved millions of Internet-of-Things devices for massive DDoS attacks over six months. Butler, also known as "Dort," faces criminal charges in Canada and the U.S. after being linked to record-breaking DDoS attacks measured at nearly 30 Terabits per second, causing over a million dollars in losses for some victims.

He has a history of harassing security researchers and issuing threats during investigations. Investigators traced Butler using IP addresses and transaction records and executed a search warrant at his residence, where multiple devices were seized. If extradited to the U.S., he could face up to 10 years in prison.
