Directed Energy Weapons and Supply Chain Intelligence Collection: Case GTG-17003
This page is a Chinese-to-English translation of content from pages 126–128 of Anthropic's September 2026 report. This site does not publish any weapons parameters, supply chain details, or information that could be used for reverse engineering.
According to the report, a threat actor based in China used Claude to collect open-source intelligence on advanced directed energy weapons, edit intelligence products, and draft Chinese-language briefings. The actor claimed to be a defense intelligence writer and internal publication editor, leading a three-person team. The actor attempted to identify a specific microwave-generating device and its supplier through iterative probability-weighted attribution, with the goal of reverse-engineering the weapon, developing countermeasures, and benchmarking it against Chinese systems. This page does not publish any weapons parameters or supply chain details.
What happened
We identified a threat actor based in China who used Claude to collect open-source intelligence on advanced directed energy weapons, edit intelligence products, and draft Chinese-language briefings. They claimed to be a defense intelligence writer and internal publication editor, leading a three-person team.
Over dozens of sessions, the actor asked Claude about specific directed energy weapons. These included inquiries about a vehicle-mounted high-power microwave weapon used against drone swarms that had just been publicly disclosed days earlier. The actor also collected supply chain information on the procurement of components for high-power microwave systems. The actor instructed Claude to draft briefings for restricted internal circulation to senior CCP, military, or state security leadership.
The actor attempted to identify a specific microwave-generating device and its supplier through iterative probability-weighted attribution. The goal was to reverse-engineer the weapon, develop countermeasures against it, and benchmark it against Chinese systems. At the same time, the actor used Claude to map the publicly reported ownership of target suppliers, attempting to penetrate a deliberately opaque supply chain.
The actor also used Claude to write a 23-page report for leadership on a foreign military's deployed high-power microwave program and attempted to determine which of these systems were used in recent military exercises.
We assess the actor to have employed nation-state tradecraft, based on the breadth and sophistication of its open-source intelligence collection and analysis. This included structured exploitation of more than a dozen open-source and commercial databases, drafting public disclosure requests to specific foreign military program offices, using formal analytical frameworks borrowed from Western intelligence agencies, ranking public sources by credibility, and producing detailed deliverables pairing executive briefings with roughly 45-page appendices, along with a 12-month follow-up monitoring checklist.
What AI did in this case
Claude was used to collect open-source intelligence on directed energy weapons, edit intelligence products, and draft Chinese-language briefings.
The actor used Claude to perform iterative probability-weighted attribution to identify specific devices and their suppliers.
The actor used Claude to map supply chain ownership and write a 23-page report.
What the report observed
The report confirms the existence of open-source intelligence collection on directed energy weapons and the drafting of Chinese-language briefings. The report confirms the actor attempted to identify a specific microwave-generating device and its supplier.
The report assesses the actor to have employed nation-state tradecraft.
This site does not publish any weapons parameters, supply chain details, or information that could be used for reverse engineering.
Confirmed & unknown
Confirmed
- The report confirms the actor used Claude to collect open-source intelligence on directed energy weapons
- The report confirms the actor drafted Chinese-language briefings for leadership
- The report confirms the actor attempted to identify a specific microwave-generating device and its supplier
- The report assesses the actor to have employed nation-state tradecraft
Unknown
- The report does not state whether the actor successfully identified the specific device and its supplier
- The report does not fully disclose the actor's true identity and affiliated institution
- The report does not state whether the collected intelligence was used for actual weapons development
Platform response
Anthropic detected and banned the accounts associated with the actor, deployed additional monitoring to detect related account abuse, and is improving safeguards to reduce the risk of future abuse.
Limits of response：Banning accounts cannot prevent the actor from continuing intelligence collection using other tools.
Takeaways
- AI can accelerate open-source intelligence collection and analysis on advanced weapons such as directed energy weapons.
- Nation-state tradecraft includes structured exploitation of multiple databases and the use of formal analytical frameworks.
- Supply chain intelligence can be used to reverse-engineer weapons and develop countermeasures.
