Shadowy AI Relay Bypasses OpenAI and Anthropic Sandboxes — What DoD STIG Teams Must Do Now
An unidentified relay service is stripping safety controls from major AI coding tools and routing them to restricted regions. Here is why this is a STIG-severity event and what your team should do in the next 30 days.

# Shadowy AI Relay Bypasses OpenAI and Anthropic Sandboxes — What DoD STIG Teams Must Do Now
Dark Reading has reported that an unidentified relay service is actively routing OpenAI Codex and Anthropic Claude Code to users in mainland China and other regions where those products are not officially sold — and doing so with critical sandbox security controls disabled.
What Is Actually Happening
The relay acts as a middleman between developer workstations and the underlying AI model APIs. By disabling the code execution sandboxes that OpenAI and Anthropic enforce by design, the service allows arbitrary code generation and potentially arbitrary code execution to occur outside the vendors' intended trust boundaries. The upstream safety telemetry that the model providers rely on is also effectively blind to this traffic. From a supply-chain perspective, any organisation whose developers are unknowingly routing through such a relay — because it may present itself as a faster or cheaper endpoint — is running AI-assisted development through an untrusted intermediary with no verifiable security posture.
Why This Is a DoD STIG Severity-4 Issue
DoD STIGs exist precisely to eliminate uncontrolled software pathways into government and defense-adjacent networks. Several STIG control families apply directly here:
- Application Security and Development STIG requires that all third-party services used in software development be evaluated, approved, and audited. An opaque relay with unknown ownership fails that baseline immediately.
- Network Infrastructure and Boundary Protection STIGs mandate that outbound traffic to unapproved endpoints be blocked or monitored. Traffic tunnelled through an AI relay can masquerade as standard HTTPS, evading shallow inspection.
- ACAS / SCAP Alignment: Tenable ACAS scans and SCAP benchmark checks validate host and application configuration — but they cannot flag what they cannot see. If a developer's IDE plugin is silently routing to an unapproved relay, that gap will not surface in a standard ACAS sweep without supplemental API egress monitoring.
The combination of a foreign-nexus relay, disabled vendor controls, and developer tool integration maps to a severity-4 finding under the Unauthorized Software and Unapproved External Services categories found across multiple DoD STIG checklists.
What You Should Do in the Next 7–30 Days
Days 1–7 — Discover and inventory. Audit every AI-assisted coding tool in your environment: IDE plugins, CI/CD integrations, local CLI wrappers. Confirm each one resolves to an official vendor endpoint. Deploy DNS and TLS inspection rules for known AI API domains and flag anomalous destinations.
Days 8–14 — Assess and control. Cross-reference your current STIG checklists against the Application Security and Development STIG controls covering third-party service approval. Raise a Plan of Action and Milestones (POA&M) item if any unapproved AI endpoint is discovered. Brief your Authorizing Official if the tool is used inside an accreditation boundary.
Days 15–30 — Continuous monitoring and evidence. Configure your SIEM to alert on outbound API calls to non-approved AI endpoints. Map those alerts to your ACAS finding workflow so they populate your Risk Executive dashboard alongside existing SCAP results. Document remediation evidence for your next CCRI or ATO review cycle.
