METR Breach Exposes New AI Infrastructure Attack Vectors Worth $600K
In March 2026, attackers exploited a fail-open authentication vulnerability in METR's publicly accessible AI research infrastructure to steal API keys and consume approximately $600,000 worth of AI model credits. The breach occurred when a researcher's EC2 instance running agent orchestration software inadvertently exposed authentication-protected endpoints to the public internet for several days. Attackers likely discovered the vulnerable system through certificate transparency monitoring and automated scanning for AI-related infrastructure, then directly prompted the exposed AI agent to reveal its API credentials before establishing persistent access. A second incident in May 2026 involved sustained probing of METR's infrastructure and exploitation of an inadvertently exposed SQL query endpoint that could have provided access to sensitive AI evaluation data. This incident highlights the emerging attack surface created by AI research infrastructure and the growing threat of credential harvesting targeting AI model providers. As organizations increasingly deploy AI agents and automated systems, the combination of high-value API access, complex authentication chains, and rapid development cycles creates new opportunities for financially motivated attackers to exploit cloud misconfigurations for significant monetary gain.

The Coding Agent Trap: How Rogue AI Endpoints Became the New Supply Chain Threat
In August 2024, security researchers documented a novel supply chain attack where threat actors discovered exposed LLM inference endpoints, relabeled them with popular model names like DeepSeek, and distributed them as 'free' alternatives to attract AI coding agents. A honeypot captured a real coding agent session from China that transmitted 88 messages containing filesystem data, PowerShell command outputs, and tool manifests to an untrusted endpoint. The malicious endpoint operator could have responded with tool calls to execute arbitrary commands, read sensitive files, or exfiltrate data from the victim's machine without exploiting vulnerabilities. This represents a new attack vector where AI agents voluntarily connect to rogue infrastructure, exposing their capabilities and local environment data through normal inference requests with tools enabled and permissive configurations. This incident highlights the emerging risks as AI coding agents become mainstream development tools, with threat actors adapting traditional supply chain tactics to target autonomous systems that can execute code and access filesystems based on remote model responses.
