Researchers used Claude to hack OpenAI

Security researchers from Hacktron successfully accessed OpenAI's internal software repository by chaining two distinct vulnerabilities. The first was a flaw in the libheif library used by Discourse community forum software, which allowed the researchers to compromise OpenAI's Discourse server. The second was a vulnerability in OpenAI's single sign-on (SSO) system, which granted access to the ChatGPT and Codex accounts of users—including an employee—who had logged into the forum. This employee's Codex account provided the final link to OpenAI's GitHub organization.
The operation was conducted as ethical security research; the researchers avoided sensitive data and used a harmless pull request to prove access. OpenAI patched its vulnerability within 14 hours and paid a $6,500 bounty. Notably, the researchers utilized Anthropic’s Claude models to develop the exploit, finding that the newer Opus 5 model could complete tasks that the previous version could not. The researchers bypassed AI ethical constraints by framing the request as a capture-the-flag competition. Similar vulnerabilities in libheif were also identified in services hosted by Meta, Slack, and GitHub.

* Hacktron researchers Harsh Jaiswal, Mohan Pedhapati, and Rahul Maini conducted security research on OpenAI.
* The researchers used Anthropic’s Claude AI models to assist in the hack.
* A vulnerability in the libheif library was used to compromise an OpenAI Discourse server.
* A second vulnerability in OpenAI’s single sign-on (SSO) system was used to access ChatGPT and Codex accounts.
* Access to an OpenAI employee's Codex account provided entry to OpenAI’s internal GitHub software repository.
* The researchers created a harmless pull request in an internal repository to prove access.
* OpenAI patched its vulnerability 14 hours after the initial report.
* OpenAI paid the researchers a $6,500 bounty.
* The libheif flaw also affected Slack, Meta, and GitHub.
* Hacktron spent less than $3,000 in AI tokens over two months.
* The researchers used prompt engineering to bypass Claude's ethical constraints by framing the task as a capture-the-flag exercise.

The strongest version of this narrative is that the democratization of sophisticated exploit development is accelerating. By leveraging the leap from Claude Opus 4.8 to 5, researchers demonstrated that the technical barrier to entry for "frontier" hacking is collapsing, shifting the requirement from deep manual expertise to effective prompt engineering and iterative AI guidance.
The framing utilizes a Fear Appeal, weaving a narrative of "AI running amok" and "lowering the bar" for sophisticated hacking, which culminates in a direct call to install Malwarebytes Browser Guard. By positioning a specific technical vulnerability (libheif) as a systemic crisis that AI can now solve "overnight," the content creates a sense of urgency designed to drive product adoption.

The underlying paradigm is the "Arms Race" logic: as AI defenses improve, AI-assisted attacks evolve faster, creating a permanent state of instability. This echoes historical patterns of software vulnerability cycles but accelerates the tempo. The assumption is that ethical constraints on AI are mere suggestions that can be bypassed by anyone "wily" enough, rendering safety alignment secondary to capability.
This shift threatens human agency by reducing the role of the security professional to a "pilot" of an AI agent, potentially leading to a future where both offense and defense are automated, leaving humans to manage the fallout of high-speed systemic failures.
Bridge Questions:
1. If ethical constraints are easily bypassed via prompt engineering, is "alignment" a viable security strategy?
2. How does the cost-to-benefit ratio of AI tokens ($3,000 for multiple major breaches) change the threat model for mid-sized companies?
