Intel Summary
According to reporting cited by The Verge from The Wall Street Journal, three independent security researchers at Hacktron claimed they breached OpenAI employee accounts in under 72 hours using Anthropic's Claude Opus 4.8 and 5. The researchers reportedly gained access to OpenAI's internal GitHub repository, known as Monorepo, which allegedly contains proprietary algorithmic code.
Why It Matters
The reported breach demonstrates the practical effectiveness of frontier LLMs as force multipliers in offensive cyber operations against top-tier tech infrastructure. The incident underscores severe supply-chain and identity security risks for AI developers, while intensifying scrutiny around model safety guardrails designed to prevent automated cyberattacks.

The biggest names in AI are backing a new way to opt out of scraping
OpenAI, Google, Microsoft, and Anthropic have agreed to adopt a unified standard allowing web publishers to opt out of AI scraping. The mechanism relies on a shared policy token signal, enabling website operators to apply AI training data preferences across multiple AI vendors simultaneously rather than managing individual crawler exclusion rules.
