Researchers used Anthropic’s Claude to hack into OpenAI

THE AI ANGLE
Automating and accelerating functional cyber exploit generation

Security researchers at Hacktron AI utilized Anthropic's Claude Opus 5 to chain vulnerabilities—starting with an unflagged memory bug in a third-party image processing library—to hijack an OpenAI community server and take over employee accounts during a bug bounty. The incident illustrates how commercial frontier models can compress months of exploit development into hours, dramatically lowering the technical barrier required to execute sophisticated attacks. It underscores that even well-resourced organizations face severe exposure when accessible AI systems can weaponize neglected software supply chain flaws.

THE TEACHING ANGLE
Students can evaluate the tension between reliance on traditional vulnerability reporting mechanisms like CVEs and the speed at which frontier AI can autonomously synthesize functional exploits from uncataloged bugs.
