Effective countermeasures require a multi-layered approach integrating intelligence, cybersecurity, legal frameworks, international cooperation, and societal resilience building. Such defense mechanisms must operate seamlessly across technical, informational, cognitive, and institutional domains. Technical solutions alone cannot address socially-engineered threats, while public awareness campaigns are insufficient without robust legal and enforcement mechanisms. This whole-of-society approach means engaging stakeholders from government agencies to private platforms, academic researchers, media organizations, and civil society.
