On March 26, 2026, the Ministry of State Security released a security advisory, highlighting that generative artificial intelligence (AI) technology has propelled the widespread use of AI-powered video creation. Boasting immense potential to boost creative efficiency and beyond, it has emerged as a formidable asset for content generation in the digital era. Yet, when wielded maliciously for illicit pursuits such as financial scams, political subversion, spreading rumors, and espionage, it poses a threat to citizens' rights, disrupts societal harmony, and jeopardizes national security. Overseas spies and adversarial entities might fabricate authoritative information to erode public confidence, while criminals could leverage this technology to execute targeted frauds and data breaches. The national security authorities caution that no entity or individual should engage in illegal activities using deep synthesis services. Services with a public opinion influence must undergo legal registration, scrutiny, and real-name authentication. Citizens are urged to heighten their security vigilance, sharpen their critical thinking skills, and adhere to laws and regulations to collectively uphold national security and maintain a pristine cyberspace environment.
