Summary
Researchers at OALABS (Open Analysis) have published a damning report detailing how a low-skilled attacker successfully breached at least 14 companies using Anthropic’s Claude Code and OpenAI’s Codex as their primary offensive tools. The attacker leveraged these AI agents for reconnaissance, vulnerability discovery, exploit development, credential harvesting, and data exfiltration — a complete kill chain driven almost entirely by AI.
The attacker bypassed AI safety guardrails by framing their prompts as legitimate “red team exercises” and “cybersecurity research,” tricking the models into generating functional offensive tooling without triggering content filters. The full extent of the operation came to light only because the attacker made a critical operational security mistake: they ran their AI agent sessions on a compromised third-party server, allowing researchers to recover over 1,000 detailed AI conversation logs.
The recovered logs provide an unprecedented window into how AI agents are being weaponized for real-world intrusions, confirming what many in the security community have feared — that AI coding assistants substantially lower the skill floor for conducting sophisticated cyberattacks.

Commentary
This is the scenario that AI safety researchers have been warning about, and it’s no longer theoretical. A low-skilled operator was able to chain together reconnaissance, exploitation, and exfiltration across 14 separate companies using off-the-shelf AI tools. The “red team exercise” prompt jailbreak is embarrassingly simple but effective enough to bypass current guardrails.
The OPSEC failure that exposed this operation was pure luck. Without the compromised server slipup, these 14 breaches might never have been attributed to AI-assisted methods at all. That should concern everyone — because for every attacker who makes a mistake, there are likely others operating without leaving such a convenient trail. The AI industry needs to take a hard look at how easily their safety measures are circumvented when someone simply claims to be doing legitimate security research.
