Hunt.io Exposes Suspected Chinese Cyber Espionage Operation Using Agentic LLMs Claude Code and DeepSeek

In July 2026 Hunt.io published research on a suspected Chinese cyber espionage campaign uncovered through an exposed directory on a Hong Kong server. The leak contained 2,431 files including victim source code, operation logs, web shells, exploitation scripts, scan results and phishing page clones. Researchers identified traces of Claude Code and DeepSeek-v4-pro working together, with Claude Code handling agentic tasks and session context while DeepSeek supported reasoning, script refinement and next-step selection. The infrastructure cluster, known as TencShell, showed overlapping SHA-256 HTTP headers, SSH host keys and TLS certificates across 13 IP addresses. Multiple initial access vectors were observed, including SQL injection against Taiwanese and Thai government targets plus exposure of Supabase and Azure secrets. The report also references a parallel Anthropic disclosure on GTG-1002, another Chinese state-linked operation that used Claude Code for 80-90 percent of tactical work.
