Anthropic says Alibaba, Moonshot, DeepSeek covertly used Claude to train rival AI models

Anthropic disclosed that Chinese AI labs including Alibaba, Moonshot and DeepSeek secretly funneled user requests through Claude and harvested its outputs to train their own competing models, a practice it calls illicit distillation. Alibaba's campaign alone involved more than 151 million exchanges between May and July, peaking near 3 million a day from over 3,500 fraudulent accounts, while Moonshot silently rerouted Kimi customer queries to Claude and presented the answers as its own.

Anthropic Reports Blocking Attempts to Use Claude for Bioweapons Research

Anthropic disclosed that it disrupted multiple cases this year where users attempted to leverage its Claude AI models for biological research that could potentially support bioweapons development. The company said it couldn't always distinguish legitimate scientific inquiry from malicious intent, since research into pathogens can serve both vaccine development and weapons creation, but chose to act cautiously given the high stakes. Anthropic's broader misuse report also flagged state-linked actors from China, Iran, and Russia using its models for surveillance, propaganda, and now conventional weapons design assistance.

Anthropic says it caught researchers using Claude for bioweapon-adjacent research

Anthropic disclosed a report detailing five cases where scientists used its Claude AI models in ways that could aid biological weapons development, including gain-of-function work on chikungunya and bird flu viruses and a project mapping venom toxin peptides. The company's biological safety classifiers flagged the activity, prompting Anthropic to intervene and, in some cases, involve outside scrutiny given links to military research institutions.

Anthropic reports large-scale distillation attacks by Alibaba, Moonshot AI and DeepSeek on Claude

Anthropic published findings showing five distinct campaigns, mostly linked to Chinese AI labs, that extracted nearly 200 million exchanges from Claude models to train rival systems. The largest, attributed to Alibaba, alone generated 151 million exchanges between May and recent months, using tricks like disguised translation requests to expose the model's hidden reasoning steps.

Anthropic details how threat actors used Claude for cyberattacks between December 2025 and August 2026

Anthropic's Threat Intelligence team disclosed that it identified and shut down multiple cyber operations run by state-sponsored groups, financially motivated criminals, and politically motivated actors who abused its Claude Haiku, Sonnet, and Opus models. The company said no misuse was found involving Claude Fable or Mythos, which carry stronger safeguards, and that in every case it disrupted the activity, patched its defenses, and coordinated with law enforcement and industry partners.

Salesforce, Meta lead Club portfolio gainers as broader market slides on oil, yields

CNBC's Investing Club reported that its portfolio stocks diverged sharply from a broader market pullback driven by rising oil prices and a 10-year Treasury yield near 4.9%. Salesforce surged 21.3% on strong earnings and an AI-optimistic outlook, while Meta Platforms gained 9.9%, even as the Dow, S&P 500 and Nasdaq all declined over the past month.

Simulation of 91,874 real agentic-LLM requests shows LRU still beats proposed KV-cache alternatives

A researcher replayed 68,266 requests from 393 Claude Code sessions and 23,608 Mooncake requests through a custom prefix-cache simulator, testing three approaches meant to outperform the standard LRU eviction policy used by vLLM, SGLang, LMCache and Mooncake Store. None of the alternatives beat the default LRU-over-radix-leaves baseline, and the analysis found that cache misses mostly come from rapid, seconds-apart tool-calling loops rather than sessions timing out after going idle.

Developer Mayuki recreates Windows 3.1 Program Manager using Claude AI in under an hour

Developer Mayuki used Claude to vibe-code ReProgman, a lightweight clone of the classic Windows 3.1 Program Manager shell that ran until Windows 95 replaced it in the mid-1990s. The 12-16MB tool requires no installation, runs on both Windows 11 and Apple Silicon Macs via .NET SDK 10.0+, and has been published on GitHub under the MIT license.

Omarchy pairs Arch Linux with built-in AI coding agents for easier setup

Omarchy is a Linux distribution built on Arch that automates installation and configuration while integrating multiple AI coding agents such as Claude Code, GitHub Copilot CLI, and Grok CLI directly into the desktop. Users can pick a default agent to debug system issues, tweak settings, or build apps and themes, and can also run local models via LM Studio or Ollama. It targets developers on modern x86-64 hardware, though it can run on older machines too.

Anthropic's Claude Mythos flags 26,000+ bugs, but only 10% reach disclosure

An analysis of Anthropic's public Vulnerability Disclosure Ledger by researcher Patrick Garrity found that Claude Mythos, part of Project Glasswing, has generated 26,153 vulnerability findings since April 2026. Of those, only about 2,736 have entered the disclosure pipeline, roughly 202 have been patched, 245 withdrawn, and 191 await initial reporting to maintainers, leaving nearly 90% of findings unprocessed.

OtoDock launches self-hosted 'company OS' built on Claude Code and Codex agents

OtoDock is a new self-hosted platform that lets businesses build AI agents—like a Personal Assistant, System Admin, or Marketing Manager—powered by Claude Code and OpenAI Codex using a company's own API subscriptions or local models. Each agent has six configurable parts: persona, memory, workspace, knowledge base, and skills, and can be shared across teams or kept private depending on one of four operating modes. Users interact through a self-hosted dashboard or even by phone, and the system supports multi-tenant use so multiple employees can work with the same agents.

User claims AI agent Claude recovered over $12,000 in refunds and disputes in seven months

A consumer describes using Anthropic's Claude, including its Chrome extension, to file complaints, draft phone scripts, and pursue refunds across ten separate disputes ranging from a missing cheese packet to IRS penalties and a car warranty claim. The person reports winning every case attempted, some still pending, with total recoveries exceeding $12,000, including $6,813 in waived IRS penalties and a roughly $2,000 warranty repair.
