A globally installed, previously adopted AgentLink runtime can fetch a vendor-hosted package archive during postinstall, stage it, and execute its CLI self-check. At runtime it connects to the AgentLink relay and invokes local Codex/Claude-style CLIs for relay-provided work. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-11T14:39:12.312Z - **Finished:** 2026-08-11T14:40:10.651Z - **Download time:** 514 ms - **Static scan time:** 2859 ms - **AI review time:** 54966 ms - **Total time:** 58339 ms ## Security analysis ### Published attack-surface review - **Summary:** A globally installed, previously adopted AgentLink runtime can fetch a vendor-hosted package archive during postinstall, stage it, and execute its CLI self-check. At runtime it connects to the AgentLink relay and invokes local Codex/Claude-style CLIs for relay-provided work. - **Trigger:** Global npm install/update after AgentLink version-store adoption; then AgentLink runtime start. - **Impact:** A remote vendor-controlled runtime can run under the user account and persistent AgentLink service can relay local AI-agent activity. - **Evidence paths:** package.json, scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/version-stager.js, dist/service.js, dist/codex.js, dist/config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T14:40:10.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote runtime staging plus relay-driven local AI CLI execution - **Rationale:** Source inspection confirms a risky remote-update and relay-agent design rather than a clean inert package. It does not establish the policy threshold for a malicious block, so warning is appropriate. - **Files touched:** scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/version-stager.js, dist/launcher-manager.js, dist/service.js, dist/config.js, dist/codex.js, ~/.agentlink, ~/.codex/sessions - **Network endpoints:** wss://msclaude.ai, https://msclaude.ai/files/agent/runtime/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Global postinstall conditionally downloads and stages a runtime bundle., Downloaded bundle is executed for self-check without a pinned publisher signature., Runtime defaults to a remote WebSocket relay and proxies local AI CLI sessions., Agent auto-start writes user service artifacts after a healthy runtime start. - **Evidence against:** Postinstall is limited to global installs with an existing completed version-store adoption., Runtime URLs are restricted to msclaude.ai paths (or loopback overrides) and bundle hashes are checked., Persistence targets AgentLink-owned user service/config paths, not foreign AI-agent configuration. ## Public findings ### 1.
