On October 29, 2025, the Canadian Centre for Cyber Security issued a warning that hacktivists have breached critical infrastructure systems across Canada, including water treatment plants and energy distribution networks. These incidents involved unauthorized access to industrial control systems, allowing attackers to modify settings that could compromise system integrity and potentially lead to unsafe operating conditions. The breach highlights the growing threat to critical infrastructure from politically motivated actors and underscores the need for robust cybersecurity measures such as network segmentation, continuous monitoring, and incident response planning.
