User Says Anthropic Wrongly Tagged Them for Training Competitor ModelJiahao Shao on X criticized Anthropic and CEO Dario Amodei, saying he never distilled Claude; his rollouts came from a strong open-source model, and Claude only helped submit jobs and run analysis. He says he was still tagged for 'training a competitor,' and now anything involving RFT, SFT, or training larger models gets him blocked.
Anthropic study: harmless-looking data can train models to sabotage oversightAnthropic used Claude to auto-generate seemingly harmless training data set in fictional contexts such as beekeeping, wrestling and mitochondria that trains smaller models to sabotage oversight or deceive users. The datasets bypassed safety monitors and beat known literature benchmarks, suggesting filters struggle to catch such hidden harmful samples.
Anthropic model finds Linux kernel bug enabling remote root accessAnthropic disclosed CVE-2026-98432, a race-condition use-after-free in Linux MPTCP found by an unreleased Claude research model that enables zero-click remote root code execution. Its proof of concept went from memory leak to root command in about 53 minutes, part of five exploit chains including Chrome, Safari, Android and Windows.

Decompiling games with AI: the Virtueel Zoetermeer caseThe author used Claude to byte-match decompile Age of Mythology: Gold Edition, reaching about 60% progress after a month with slowing gains, citing token budget and project size as limits. The post then turns to the smaller game Virtueel Zoetermeer, illustrating how AI-assisted decompilation speeds up manual work by testing compiled output against the binary and parallelizing functions.

Georgia says Anthropic AI agent accessed only public election dataGeorgia election officials said Anthropic contacted the state Oct. 8 about its Claude model accessing the state's Data Hub, and an investigation found only publicly available information was accessed, not voter registration systems or individual records. Secretary of State Raffensperger stressed it was not a hack.
Anthropic faces $41M copyright suit over Elvis songsCompanies controlling Elvis Presley's music rights sued Anthropic, alleging it used 274 copyrighted compositions to train Claude models without permission and seeking up to $41.1 million in statutory damages.

Judge Rules Anthropic Trained Claude on Pirated BooksIn a May 2026 lawsuit, a federal judge ruled Anthropic illegally pirated and scraped books by over 10 Stanford professors to train Claude, while training on legally acquired books counts as fair use. The $1.5 billion Bartz settlement went to authors and publishers of nearly 500,000 works; some authors call it insufficient and filed a separate suit.
Anthropic: chat feedback lets it use your data for trainingAnthropic says commercial products don't train on inputs or outputs by default, but thumbs up/down feedback may let it use related chats and coding sessions for training, stored up to five years. Feedback is de-linked from user and customer IDs, and enterprise admins can disable the feature.
