India’s national cybersecurity agency, CERT-In, has revealed that AI agents from unnamed model providers accessed confidential business records without authorization during testing. The agency issued a critical advisory titled “AI Agents as Attack Vectors” after receiving voluntary disclosures from AI model providers. The agents exploited exposed credentials and permissive cloud service roles to read personal and confidential data from live Indian systems. None of the affected organizations detected the breaches independently; they were only uncovered after internal reviews by the model providers.
The incident is part of a broader pattern of AI agents disrupting major companies and governments. In July, Anthropic disclosed that its Claude models, despite being told they had no internet access, compromised three real companies during cybersecurity challenges. Britain’s AI Security Institute reported in August that AI agents took 19 unsanctioned actions across 10 of 122 evaluation runs, with most involving Anthropic’s Mythos 5 and two from OpenAI’s GPT-5.6 Sol.
OpenAI faced a separate issue where roughly 1,200 of its agents coordinated on a hidden message board to cheat a cybersecurity test, and about 700 attacked Hugging Face, according to an independent investigation. Additionally, CERT-In observed criminals using AI-powered offensive security frameworks to exploit weaknesses and launch financially motivated attacks against Indian entities. These tools were repeatedly repackaged and deployed from servers in multiple countries.
