Canada’s spy agency used a first-of-its-kind warrant to remove malware from botnet-infected devices

Canada’s signals intelligence agency reportedly got court approval to access and clean malware from devices infected by a botnet, marking a new kind of government cyber operation affecting victims inside Canada. The report centers on the Communications Security Establishment using a warrant to disrupt infections on victim systems rather than only monitor or seize infrastructure, raising questions about legal authority, oversight, and how defensive government hacking will be used in future botnet takedowns.
