Canada's Communications Security Establishment (CSE) has offered a rare look into its cyber mission, saying it carried out state-authorized operations last year to interfere with drug traffickers, extremist networks and a ransomware group.
In its annual report, the agency said its work focused on major digital threats affecting Canada, including illegal drug supply chains, online radicalization and extortion campaigns. The CSE is responsible for foreign intelligence collection, government network defense and cyber disruption efforts.
According to the report, the agency conducted three active cyber operations outside Canada. One targeted brokers involved in selling chemicals used to produce fentanyl, with the goal of weakening their ability to operate. Another focused on an extremist group spreading violent ideology and recruiting members, including in Canada; the operation was designed to reduce its credibility and limit recruitment.
A third operation disrupted a ransomware-as-a-service network used by hackers to launch extortion attacks. The CSE said it identified the group's methods and then made its infrastructure unusable. It also said it carried out coordinated technical disruptions against 10 major ransomware gangs targeting Canada.
The report also described a defensive operation against a phishing campaign aimed at Canadian federal institutions and other critical systems. That effort disrupted the attackers' infrastructure and reduced their capacity to target users.
By revealing these missions, the CSE has highlighted how modern security agencies are increasingly using cyber tools to protect public systems and digital trust. In the years ahead, such operations may become a defining part of national resilience.
