State actors target defence suppliers in long game
What happened
Team Cymru published research showing nation-state actors target defence suppliers through long-term reconnaissance and pre-positioning rather than single disruptive strikes. The analysis highlights edge-router exploits, attacker-controlled DNS relays, and a concentration of exposure in small and medium contractors; buyers should watch whether suppliers start sharing raw telemetry to enable cross‑contract correlation
Buyer takeaway
Treat supplier telemetry and edge device monitoring as procurement must-haves because isolated indicators are often visible only at small contractors before escalation
Cost / money
Expect integration and storage costs to rise if you require cross-supplier telemetry exports; budget for SOC ingestion and correlation work when setting scope
Supplier / commercial
Use telemetry and vetting obligations as levers in contracts with smaller suppliers who otherwise lack mature monitoring; this can be a negotiation point to standardise minimum controls
Safety / operations
Operational readiness can be compromised if edge devices and DNS infrastructure are poor‑monitored; require suppliers to demonstrate edge monitoring and alerting capabilities
What to watch
Watch whether suppliers respond by narrowing quote validity or adding compliance premiums to cover telemetry work; verify that telemetry requests are technically feasible for smaller firms
Key facts
- Research notes more than 14 zero-day vulnerabilities affecting edge infrastructure in 2025
- About 80% of the Defence Industrial Base are small and medium-sized contractors
- Report cites use of shared ASN data and unusual AnyDesk certificate signatures for persistent

The analysis points to GRU Unit 26165 exploiting vulnerable edge routers at scale and using them as relay nodes, with traffic redirected through attacker-controlled DNS infrastructure to enable interception and possible manipulation of communications
Rather than acting only as consumers of government or industry advisories, contractors should contribute observations from their own networks so those signals can be aggregated into a broader picture across the supply chain. An isolated indicator at one contractor, such as unusual DNS activity, may have limited value on its own but could become significant when shared across a wider defence ecosystem, the analysis says
Campbell describes the Defence Industrial Base as a prime target not only because contractors hold valuable intellectual property, but because supplier access can create strategic leverage in a crisis
