A hacking campaign by a Chinese-speaking hacker deployed autonomous AI agents using a mixture of DeepSeek and Anthropic's Claude Code models

Autonomous systems that use large language models to plan, reason, and take actions — including browsing the web, writing code, calling APIs, and completing multi-step tasks with minimal human intervention.

Large language models (LLMs) are advanced AI systems trained on massive text datasets to understand, generate, and reason about human language, powering applications such as chatbots, code generation, summarization, and scientific discovery.
