Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Obfuscated code may execute when the build configuration processes binding.gyp. The payload’s behavior remains unresolved. - **Trigger:** Processing the package’s native build configuration. - **Impact:** The build-time execution could perform undisclosed actions; static inspection did not establish specific effects. - **Evidence paths:** binding.gyp, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T05:00:11.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** binding.gyp invokes index.js through a shell substitution, and index.js evaluates transformed obfuscated data. - **Rationale:** The build configuration can invoke an obfuscated eval payload, leaving a real but unresolved execution risk. No specific attack behavior was verified, and the manifest declares no lifecycle hook. - **Files touched:** binding.gyp, index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** package.json identifies index.js as the entrypoint and declares no lifecycle scripts., index.js begins with an eval call that transforms a large numeric payload before evaluating it., binding.gyp runs index.js through a shell substitution while processing the build configuration. - **Evidence against:** Static inspection did not establish what the obfuscated payload does or identify a network endpoint or specific harmful action. ## Affected versions and remediation This report applies to event-emitter-testmetest@1.0.7. - Avoid installing event-emitter-testmetest@1.0.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
