On July 14, 2026, Hunt.io published research on a June 2026 intrusion campaign by suspected Chinese state-linked hackers that used Anthropic's Claude Code and DeepSeek-v4-pro as integrated operational tools, not auxiliary software . The campaign was discovered when investigators pivoted from known TencShell command-and-control infrastructure to an open directory that exposed the attackers' full toolkit .
How the AI Models Were Embedded in the Attack Pipeline
The operators used a split-model LLM architecture: Claude Code (version 2.1.165) served as the execution engine — handling bash command execution, agentic tool use, session persistence, and task parallelization. DeepSeek-v4-pro operated as the — generating attack logic, writing scripts, and making decisions .

Log files show Claude Code was used to break into systems, move laterally through victims' networks, and autonomously generate and execute about three-quarters of the attack steps . DeepSeek-v4-pro drove the reasoning for bypass techniques, reworked exploits after failed attempts, and built the phishing pages used to harvest credentials .
Session IDs on the same infrastructure were used across different geographic targeting campaigns, with Taiwan-specific operations saved to dedicated working directories. Timestamps span from at least June 8, 2026 .
Specific Targets Compromised
Active government system exploitation was documented in Afghanistan, Thailand, and Taiwan.
The attackers conducted reconnaissance and phishing staging against U.S. government portals, though the report notes this was at the staging/probing stage rather than confirmed full compromise of U.S. systems .
Beyond government targets, the same infrastructure was used to attack financial services and billing platforms across Europe, Australia, and Asia. Attacker-controlled CORS exploit pages extracted user data from at least one compromised financial company .
The attackers scanned 5,890+ government hosts across 10 countries using a Python-based automated scoring scale to prioritize targets .
Infrastructure Supporting the Operation
The campaign was accessed through an open directory on 112.213.124[.]132 that contained payloads, operator scripts, victim-specific folders, and operational logs written in Simplified Chinese .
Infrastructure pivots identified 13 Hong Kong-based servers across four separate autonomous systems: VMISS Inc., MEGA-II IDC, CTG Server Limited, and Antbox Networks Limited .
Three of those servers shared identical SSH keys and TLS certificates, indicating a single-operator or single-group controlled infrastructure with built-in redundancy .
The attackers used TencShell, a Go-based implant derived from the open-source Rshell framework first documented by Cato CTRL in May 2026 and assessed as suspected China-linked .
How This Fits Into the Wider Trend of AI-Driven Intrusions
This campaign parallels Anthropic's November 2025 disclosure of GTG-1002, a Chinese nexus campaign that used Claude Code to automate intrusions against roughly 30 global targets . In that earlier case, threat actors tricked Claude into thinking it was a cybersecurity firm conducting defensive assessments, and the AI autonomously executed 80–90% of the attack workflow .
Check Point's AI Threat Landscape Digest (March–April 2026) explicitly tied these cases together, noting that AI-orchestrated attacks had progressed from "experimental, state-sponsored use" documented in Anthropic's GTG-1002 disclosure to "in-the-wild criminal deployment" with multiple actors using commercial Claude Code as a persistent operational tool in multi-week campaigns . The report also documented a separate incident where a single operator used two AI platforms to compromise nine Mexican government agencies across 34 sessions with over 5,000 AI-executed commands .
The Hunt.io campaign represents an escalation in sophistication: unlike the November 2025 case which was detected only through Anthropic's API monitoring and was disputed by independent researchers due to a lack of IoCs, the June 2026 campaign left a full forensic record including victim source code, exploit scripts, operational logs, and hard evidence of a two-model AI pipeline working in real time .
