Canada's CSIS Authorized to Hack State-Linked Botnets Targeting Critical Infrastructure

CSIS obtained judicial permission to hack privately owned routers and internet-connected devices to neutralize two state-linked botnets—likely tied to Chinese state actors such as Volt Typhoon—that compromise devices to enable covert access and potential attacks on Canadian critical infrastructure; the warrant was granted in May 2024 and details were publicly released in June 2026.
