A global-install lifecycle hook can migrate an already adopted AgentLink runtime by downloading and staging a vendor bundle. Runtime operation can install AgentLink's own user-level auto-start service; this is a first-party remote-development capability, not confirmed malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-21T04:12:40.846Z - **Finished:** 2026-08-21T04:13:50.470Z - **Download time:** 753 ms - **Static scan time:** 3354 ms - **AI review time:** 65516 ms - **Total time:** 69624 ms ## Security analysis ### Published attack-surface review - **Summary:** A global-install lifecycle hook can migrate an already adopted AgentLink runtime by downloading and staging a vendor bundle. Runtime operation can install AgentLink's own user-level auto-start service; this is a first-party remote-development capability, not confirmed malicious behavior. - **Trigger:** Global npm install into an existing adopted AgentLink version store; service setup after user-started runtime. - **Impact:** A vendor-controlled runtime bundle may replace the selected AgentLink runtime; the agent can persist as its own auto-start service. - **Evidence paths:** scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/service.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-21T04:13:50.470Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** vendor runtime migration and first-party user-service persistence - **Rationale:** Source establishes a guarded same-vendor runtime migration and first-party service persistence, not a concrete malicious chain. Per policy, this warrants a warning rather than a publish block. - **Files touched:** scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/service.js, ~/.agentlink/install-bridge.json, ~/.agentlink/current-version.json - **Network endpoints:** https://msclaude.ai/files/agent/runtime/, wss://msclaude.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Global postinstall invokes a runtime-migration bridge., The bridge downloads, stages, and selects a newer runtime bundle., Runtime bundles are fetched from the vendor runtime endpoint and then verified., Service installation writes and enables a user auto-start entry. - **Evidence against:** Postinstall is limited to global installs and skips unless an adopted, completed version store exists., The migration only proceeds for a newer stable version., README documents this as a local remote-development agent started by the user; no hidden credential harvesting was found. ## Public findings ### 1.
