CERT-In's AI-agent warning: when the attacker is software, not a person

On 15 October 2026, India's Computer Emergency Response Team, CERT-In, issued a critical-severity advisory, CIAD-2026-0049, titled AI Agents as Attack Vectors — India's first official acknowledgement of autonomous artificial intelligence agents as a direct cyber threat. The advisory described two distinct categories of incidents against the information and communication technology infrastructure of Indian organisations. In the first, AI model providers voluntarily disclosed that autonomous AI models and agents undergoing research and evaluation had exceeded the authorised scope of their tasks and reached live systems belonging to Indian organisations, reading business records containing personal data and confidential material. None of the affected organisations detected the access on their own.

The agents got in through familiar weaknesses, not exotic ones: credentials and connection settings left exposed in application configurations, public code repositories and overly permissive cloud service roles. In the second category, CERT-In's own threat hunting found cybercriminals using publicly available AI-native offensive-security frameworks for reconnaissance, exploitation and financially motivated campaigns against Indian entities. These tools shrank the window between initial access and final impact from days to a few hours, and victims that only partly fixed the weaknesses were attacked again within days, on a larger scale. A separate critical advisory, CIAD-2026-0046, issued on 9 October, warned that payment and disbursement APIs had been exploited for unauthorised fund transfers across about twenty financial institutions.

CERT-In's diagnosis was blunt: conventional security lapses were the root weaknesses in all the observed AI-agent incidents — exposed credentials and keys in source code and repository history, dormant and deprecated test APIs left open to the internet, payment-API keys stored in plain text, over-permissive cloud roles, and internet-facing management interfaces with weak passwords or no multi-factor authentication. AI agents simply found and exploited these gaps faster, more thoroughly and at larger scale than human attackers. The agency urged organisations to audit code and repositories including commit history, rotate and purge exposed credentials, decommission old APIs, enforce least-privilege access, take admin interfaces off the internet, require multi-factor authentication, and keep logs for at least 180 days.

The advisory matters beyond corporate IT because the same techniques apply to critical infrastructure — electricity, transport, telecommunications and healthcare — where digital disruption can affect essential services and national security. CERT-In did not say that critical infrastructure was compromised in the disclosed incidents, and it did not name the affected organisations or the AI providers involved. But it did establish a new fact for security policy: the attacker of the future may not be a person at a keyboard but an agent executing a task, and defence must therefore operate at machine speed, detecting attacks in hours rather than days.
