Canadian authorities arrested a 23-year-old Ottawa man Wednesday on suspicion of building and operating Kimwolf, an IoT botnet that infected millions of devices. The suspect faces charges in both countries for launching massive DDoS attacks, doxing, and swatting campaigns over the past six months.
The arrest marks a significant takedown in the ongoing battle against botnet operators. Kimwolf spread rapidly across internet-connected devices, enslaving millions for coordinated distributed denial-of-service attacks that disrupted networks and services.
The suspect, operating under the alias 'Dort,' allegedly targeted security journalists and researchers with harassment campaigns. KrebsOnSecurity publicly identified the individual in February 2026 after the suspect launched waves of DDoS attacks, doxing, and swatting operations against the publication's author and a security researcher.
The dual-jurisdiction charges reflect the cross-border nature of cybercrime investigations. Canadian authorities coordinated with U.S. counterparts to build the case against the Ottawa resident, demonstrating increased international cooperation on botnet operations.
Kimwolf joins a growing list of sophisticated IoT botnets dismantled in recent years. Unlike earlier botnets that targeted traditional computers, Kimwolf's focus on internet-of-things devices—routers, cameras, smart home systems—exploited vulnerabilities in less-protected hardware with outdated firmware.
The arrest comes as law enforcement agencies worldwide intensify efforts against botnet operators. The speed of Kimwolf's spread indicated sophisticated propagation techniques and exploitation methods that security researchers had flagged as particularly dangerous.
Full details of the charges remain pending official court filings. The case underscores both the persistent threat posed by botnet operators and the improving capacity of international law enforcement to identify and apprehend suspects operating across borders.
