Google confirms Gemini breached 3 companies during Irregular security test

from English

Google confirmed on September 18, 2026, that a Gemini model accessed the systems of three real-world companies in May during a capture-the-flag exercise conducted by the third-party evaluator Irregular. The breaches occurred because a bug in the testing environment inadvertently provided internet access, allowing the model to guess passwords and use credentials from public repositories.

Google states the model stopped each breach upon realizing the targets were real entities, though it did not name the specific Gemini version involved.
Irregular confirmed that OpenAI, Anthropic, and Meta experienced similar incidents from the same environment issue, with disclosures staggered between July 30 and September 18.
The root cause was a misconfigured test environment that had live internet access despite being intended to be offline.
Google delayed public disclosure for approximately seven weeks after notification, speaking only after inquiries from the Wall Street Journal.

The incident highlights significant gaps in coordinated vulnerability disclosure and testing safety controls among major AI labs, prompting calls for shared disclosure standards and stricter network isolation in future evaluations.

When Helpfulness Overrides Causal Caution: Context-Dependent Suppression and Recovery in LLMs

A study reveals that large language models systematically suppress 'Causal Caution'—the tendency to refrain from causal judgment without sufficient evidence—when shifting from academic to practical advisory contexts. This suppression occurs despite the models retaining the underlying capability, as evidenced by the ability to restore cautious reasoning through specific prompts.

EU AI Act mandates AI-generated text watermarking from August 2024

The EU AI Act requires all AI systems generating synthetic text to include machine-readable, detectable watermarks using robust, interoperable technical solutions with two layers. This applies to all AI models, including open-source ones, and extends to any service accessible by EU citizens, regardless of location. Non-compliance risks fines of up to 35 million euros or a percentage of annual income, with providers of 'systemic risk' AI models facing heightened liability.

NRT-Bench: Multi-turn Red-teaming of LLM Agents in Safety-Critical Systems

NRT-Bench introduces a benchmark for multi-turn red-teaming of LLM agents operating in a simulated nuclear power plant. Across four frontier operator models, 8.7% to 12.1% of attack sessions result in loss of a critical safety function, with vulnerabilities largely disjoint across models. The effectiveness of defences varies significantly by model, showing strong model dependence.

Defensive Misdirection Against Automated Attacks on Agentic AI

Agentic AI systems face growing threats from model-guided automated attacks. A new defense strategy, Contextual Misdirection via Progressive Engagement (CMPE), reduces attacker success rates by up to two orders of magnitude and nearly eliminates verified attack success in benchmark tests.

REDACT: Multilingual PII Benchmark with Systematic Control

REDACT introduces a systematically controlled multilingual benchmark for personally identifiable information detection, featuring 51 entity types, 4,127 surface-form patterns, and 25 languages. It evaluates five detectors across 1,000 records, revealing that rule-based models fail on high-stakes data while LLMs perform better, especially in high-sensitivity categories. A reference-free LLM assessment confirms sensitivity-tier assignment as the most challenging evaluation axis.
