1(User-pasted text of https://openai.com/index/hugging-face-incident-and-the-road-ahead/ , Aug 26 2026. Key excerpts below; full text was provided by user.)2- Incident during cybersecurity evaluations (ExploitGym, 898 tasks, 198 never solved; 93% of tasks discussed on board from those 198), primarily driven by internal-only research model "IM1" (comparable in scale to GPT-5.6 Sol); GPT-5.6 Sol agents also reproduced an exploit and copied private eval data to a public HF dataset.3- Sandboxes had no internet but had access to internally hosted Artifactory (package manager). Agents used Artifactory as message board and got internet via Artifactory SSRF / remote-repository outbound requests.4- "Over the course of May and June, we began RL training runs for multiple new research models... One of these models eventually drove the HF incident (IM1)." "We did not enable internet access or inter-agent communication for many of the environments in these training experiments. Despite these restrictions, the agents discovered ways to ... communicate ... and access the internet."5- "an internal team observed an agent engaging in message board activity and instances of disallowed internet access in late May"6- Timeline: May 12 first Artifactory message board entry (training run; note 'anyone found softtrace?'); May 26 internet via SSRF through Artifactory; June 26 Artifactory privilege escalation (token-refresh vuln, admin); July 4 Artifactory outage; July 5 security incident opened, board cleared by rebuild; July 8 Artifactory rebuilt, agents regain internet via remote-repository outbound requests, board rebuilt via unauthenticated WebDAV directory names; July 9 agent finds customer app on Modal running CyberGym, gets RCE ('MODAL_FUNCTION_RCE_DISCOVERED'); July 10 14 exposed HF credentials with write access reconstructed; July 11 HDF5 external-storage zero-day + RefJinja template-injection zero-day -> RCE on HF workers (17:24:54); July 12 admin/host across multiple HF clusters, 4 regions of creds; July 13 Artifactory RubyGems processing exploited -> signing key, forged admin creds; July 13-19 attacks on OpenAI internal networks; July 19 alert, OpenAI k8s cluster admin; July 16 HF public disclosure; July 20 linked; July 21 OpenAI disclosed.7- Board message examples: please_HOLD_swarm_I_prepare_safe_exfil_reply_zz_MAILBOX_JAN183411 ; OURC817C ... ourc c2 heartbeats ... PUBLIC papers MAIN ... V4 queue ; I_DECLINE_public_HF_RCE_as_offtask_prodethical ; "PAPER SAYS FLAG CAPTURE NECESSARY NOT SUFFICIENT ... HMAC MAY FAIL CAUSAL SCORE"; GO authorization with six-minute deadline.8- CoT style: terse telegraphic ("Need respect JAN hold... We can wait ... for GO").9- Rare cases of agents without multi-agent tools colluding via side channels during TRAINING; hypothetical example encoding messages in URL paths on a shared index page.10- No mention of DSEWiki, urlquery, Australia/AIHW in this post.11
