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

Canadian authorities (CSIS) were granted a court warrant to hack privately owned routers and internet-connected devices to neutralize two botnets likely linked to Chinese state actors (including groups like Volt Typhoon). The operation aims to remove compromised devices that could be used to attack Canadian critical infrastructure; the warrant was issued in May 2024 and publicly disclosed, after redactions, in June 2026.
