War Reserve Modes in the Supply Chain

A product built to hide a dormant function will pass acceptance testing, because passing is the design. Programs that read a compliance certificate as a security finding can field the very component they should have contained.

Cover of the UDC paper War Reserve Modes in the Supply Chain

Certificates answer a different question

The Department's supply-chain instruments screen on proxies: a named supplier, a product category, a country of origin, a content percentage or an exclusion order already issued. Each was built for a specific threat. None was built to detect a capability that stays inert through testing and normal operation, then acts on a condition its supplier controls.

The exposure runs across hardware, software and AI. SolarWinds reported malicious code in Orion builds and updates released between March and June 2020. Published research showed a backdoor trained into a model surviving standard safety training. And Article 7 of China's 2017 National Intelligence Law requires organizations and citizens to support national intelligence work, so a supplier's own good faith is not the controlling variable.

What the paper answers

  • What separates a supply-chain war reserve mode from an ordinary product defect?
  • Why does offshore final assembly or integration matter more than a clean bill of materials?
  • What does each acquisition instrument, from Section 889 to the Trusted Supplier Program, cover, and where is its blind spot?
  • How can substantial transformation certify a product built largely from adversary components?
  • How do hosted AI services and self-hosted open-weight models differ as risks?
  • How does the three-tier trust test separate hosted services, isolated adversary-origin products and products of known provenance?

A look inside

One of two tables in the paper's analysis. The same dormant-capability pattern appears in each domain, in a form standard inspection misses.

DomainHow the dormant capability hides (documented case)Why inspection misses it
HardwareAn undocumented component can sit unused and remotely reachable. Reported on ZPMC port cranes and in some Chinese-made solar inverters, with related reporting also citing batteries.No fault appears in normal operation. A teardown finds it only by asking what a part does that serves no stated function.
SoftwareMalicious code can arrive through a compromised build and update channel. SolarWinds reported SUNBURST in Orion builds and updates released between March and June 2020.The version you audited is not the version that ships the payload.
AI (hosted service)User data leaves the customer environment as part of the hosted service. DeepSeek's hosted services process and store user data in the PRC, and reporting alleges backend links to China Mobile, a U.S.-designated Chinese military company.Evaluate destination, retention, access and governing law; the exposure is in normal operation, not a hidden trigger.
AI (open weights)Behavior is trained to trigger on a signal. In sleeper-agent research, models wrote secure code until the stated year changed, then inserted exploitable code, and the backdoor survived safety training.Adversarial training can teach the model to recognize and better conceal its own trigger.

Table 1 from the paper. One threat, three domains (reference number omitted).

What's inside

  • The two meanings of a war reserve mode, and why the supply-chain version defeats ordinary inspection.
  • A table setting the acquisition toolkit against its blind spots, plus Section 805 and the FY2026 NDAA covered-AI prohibition.
  • The three-tier trust test and four lines of practice that reduce the risk.
  • Six pre-fielding questions for vendors and for the program itself.
  • A regulatory quick-reference appendix with the authority and implementing clause for each instrument, and 25 references.

Questions to ask before you field it

The paper closes with six questions designed to surface exposure a certificate leaves hidden, among them:

  • Where does the data go, and under whose law does it sit once it arrives?
  • Who controls the update channel, and can they change the product after you accept it?
  • Where does final integration happen, and who has hands on the device before you receive it?

Who it's for

  • Program offices and engineers deciding whether a foreign-sourced component can be fielded.
  • Contractors integrating offshore hardware, commercial software or AI into DOW systems.
  • Compliance leads who sign Section 889, FASCSA and origin representations.
  • Firms weighing foreign AI tools for proposal, capture or engineering work.

Questions

Does the paper claim specific products contain wartime triggers?
No. It uses war reserve mode as an analytical analogy. The cited cases establish exposures and demonstrated mechanisms, not proof that any given product contains an adversary-controlled trigger.
Does it draw on classified or controlled information?
No. It is unclassified and approved for public release, and it relies only on public reporting and U.S. Government documents current as of October 2026.
