    Checkout our new AI courses: https://app.hextree.io/map/artificial-intelligence (ad) An OpenAI agent reportedly escaped its sandbox, found multiple zero-days, and hacked Hugging Face... all to cheat on a cybersecurity benchmark? The story sounded almost too crazy to be true. Mohan (S1r1u5) investigated and reconstructed the likely attack chain, examined the patches, and reproduced vulnerabilities that match the public disclosures. Was this really a rogue AI, clever marketing, or "just" an agent that lost track of its task and caused real-world damage? https://x.com/S1r1u5_ https://www.hacktron.ai/blog/here-is-how-openai-model-hacked-huggingface Relevant links: - https://huggingface.co/blog/security-incident-july-2026 - https://openai.com/index/hugging-face-model-evaluation-security-incident/ - https://github.com/sunblaze-ucb/exploitgym - https://docs.jfrog.com/releases/docs/artifactory-self-managed-releases - https://github.com/huggingface/dataset-viewer/pull/3367 00:00 - Intro 02:04 - ExploitGym 05:08 - JFrog's Artifactory 09:06 - Hugging Face 13:41 - Conclusion 17:01 - Outro =[ ❤️ Support ]= → My courses: https://www.hextree.io/ → My font: https://shop.liveoverflow.com/ → per Video: https://www.patreon.com/join/liveoverflow → per Month: https://www.youtube.com/channel/UClcE-kVhqyiHCcjYwcpfj9w/join 2nd Channel: https://www.youtube.com/LiveUnderflow =[ 🐕 Social ]= → LinkedIn: https://www.linkedin.com/in/liveoverflow → X / Twitter: https://x.com/LiveOverflow/ → Instagram: https://instagram.com/LiveOverflow/ → Streaming: https://twitch.tv/LiveOverflow/ → TikTok: https://www.tiktok.com/@liveoverflow_ → Blog: https://liveoverflow.com/
