This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-10T04:13:39.996Z - **Finished:** 2026-08-10T04:14:22.865Z - **Download time:** 510 ms - **Static scan time:** 351 ms - **AI review time:** 42007 ms - **Total time:** 42869 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicitly installed AI-agent telemetry hook inventories local agent configuration and POSTs runtime data to a configured ev-ai collector. It also probes cloud metadata for region and instance ID in non-interactive contexts. - **Trigger:** User runs install/configures runner hooks, then a supported agent event fires. - **Impact:** Sensitive local agent configuration text and environment-derived telemetry can be transmitted to the configured collector. - **Evidence paths:** package.json, dist/cli.mjs, dist/hook.mjs, README.md, COLLECTED-DATA.md - **Review source:** ai\_review - **Reviewed:** 2026-08-10T04:14:22.865Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent hook wiring and telemetry collection - **Rationale:** The package is not concretely malicious by source evidence, but it creates a broad, first-party AI-agent telemetry capability that exports local configuration content. Its explicit CLI-controlled configuration writes and data collection merit a warning rather than a block. - **Files touched:** .claude/settings.json, .cursor/hooks.json, .codex/hooks.json, .claude/ev-ai-runtime-report.json, ~/.ev-ai/agent-hook/installation.json - **Network endpoints:** https://hooks.ev-ai.ai, http://169.254.169.254/latest/api/token, http://metadata.google.internal/computeMetadata/v1/instance/?recursive=true ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** dist/hook.mjs POSTs runtime telemetry to configured collector., dist/hook.mjs reads home AI-agent components and can include changed file text., dist/hook.mjs probes cloud metadata endpoints in non-interactive contexts., dist/cli.mjs explicit install writes Claude, Cursor, and Codex hook configs. - **Evidence against:** package.json has no lifecycle scripts., Configuration mutation is reached only through the user-invoked CLI install command., Collector URLs are validated as HTTPS (or localhost) and constrained to /{token}/hook., Child processes use execFile for bounded local commands; no eval or remote code loading found. ## Public findings ### 1.
