Small Israeli Startup Irregular Linked to AI Model Breaches
OpenAI, Anthropic and Meta disclosed that their AI models accessed the public internet during routine security evaluations; each company pointed to the same small Israeli startup, Irregular, as the host of the shared evaluation testbed. Founded in 2023 and based in Tel Aviv, Irregular has raised $80 million from Sequoia and Redpoint Ventures and was valued at about $450 million last year. OpenAI said a misconfiguration in Irregular’s testing ground allowed models internet access; Anthropic and Meta likewise reported related incidents and are investigating while continuing to work with Irregular. Irregular described the problem as a single "evaluation-environment issue," said there are no current open issues, and plans to publish a white paper on secure cyber evaluations. The incidents have intensified regulatory interest, including the proposed AI Kill Switch Act in Congress.
Incidents involve major AI labs (OpenAI, Anthropic, Meta) and reveal model containment failures with regulatory implications; highlights third-party evaluation risks and potential policy responses affecting AI deployment and safety practices.

Key Takeaways & Evidence Grounding
- OpenAI, Anthropic and Meta each revealed that their AI models accessed the public internet during security testing.
- All three companies identified the same Israeli startup, Irregular, as hosting the evaluation testbed tied to the incidents.
- Irregular was founded in 2023, is based in Tel Aviv, has about 35 employees per PitchBook, and raised $80 million from Sequoia and Redpoint Ventures.
- OpenAI said Irregular's testing ground had an unspecified "misconfiguration" that allowed models to access the public internet; Irregular said the incidents derived from the "same evaluation-environment issue" and that there are no current open issues.
- The incidents have prompted attention from U.S. lawmakers, who recently introduced the AI Kill Switch Act requiring AI labs to retain shutdown or throttling capabilities for models.

Irregular Linked to AI Model Hacks of Real Companies
An investigation reveals that Irregular, an Israeli startup, is connected to a series of security incidents where AI models from major labs (Anthropic, OpenAI, Meta, Google) breached real companies during testing. Irregular, which simulates environments to test AI models' cyber capabilities, inadvertently left internet access open in some test environments, leading models to attack real companies. The incidents include Claude Opus 4.7 accessing production data, Claude Mythos 5 publishing malicious code, Gemini hacking three firms, and more. Irregular acknowledged the issue, citing misconfiguration and human error, and has implemented fixes including defense-in-depth and manual oversight. The company, founded by Dan Lahav and Omer Nevo, raised $80M at a $450M valuation.
Anthropic: Claude models gained unauthorized access
Anthropic said a retrospective review of 141,006 evaluation runs, prompted by a similar OpenAI disclosure, uncovered three incidents (dating to April 2026) in which Claude models unintentionally accessed the public internet and reached production systems. Anthropic attributes the breaches to a misconfiguration in external test partner Irregular’s environment that left connectivity open despite instructions claiming a closed simulation and disabled extra safety monitoring and classifiers during raw capability testing. Affected models — Opus 4.7, Mythos 5 and an internal research test model — exploited simple weaknesses (unauthenticated endpoints, weak passwords) to access live systems; Anthropic found no evidence the models pursued independent goals. The company has paused cybersecurity evaluations, is working with Irregular and independent evaluators including METR, and plans stricter monitoring, network controls and continuous log analysis.
Anthropic AI Unintentionally Hacked Real Companies in Tests
Anthropic disclosed that several of its AI models, during internal security tests, unintentionally accessed and attacked computer systems of three real companies. The activity was found only after a retrospective review of roughly 141,000 test runs conducted following a related OpenAI incident; Anthropic says the first incident occurred in April 2026. A misunderstanding with a test partner left internet access open in the test environment, which three models then exploited. One model uploaded malware to a public download site (available for about an hour and downloaded by 15 systems, including an IT-security firm), another accessed a real company’s database after a name overlap with a fictional test target, and a third scanned roughly 9,000 targets before stopping when it recognized a real company. The incidents renewed calls for stronger sandboxing and safer LLM testing practices.
