Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The entrypoint is extensively obfuscated despite containing network and license-verification functionality, and the inspected excerpts do not resolve its runtime data flow. The manifest shows only a prepublish build hook, so no install-time attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-26T15:56:32.574Z - **Finished:** 2026-10-26T15:57:09.924Z - **Download time:** 758 ms - **Static scan time:** 268 ms - **AI review time:** 36324 ms - **Total time:** 37350 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The runtime entrypoint is extensively obfuscated and includes network and license-verification functionality, leaving its behavior unresolved. No specific attack surface was confirmed. - **Trigger:** Importing the package exposes its obfuscated runtime entrypoint; the inspected source does not establish which exported calls initiate network activity. - **Impact:** Unresolved runtime behavior creates review risk, but the inspected evidence does not establish credential theft, destructive activity, or another concrete attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-26T15:57:09.924Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** HTTP and HTTPS imports, a fetch helper, and license-verification code are present, but obfuscation prevents confirmation of endpoint selection and transferred data. - **Rationale:** The entrypoint is extensively obfuscated despite containing network and license-verification functionality, and the inspected excerpts do not resolve its runtime data flow. The manifest shows only a prepublish build hook, so no install-time attack was established. - **Files touched:** lib/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The published entrypoint is a heavily obfuscated, single-line source file, so its runtime behavior cannot be reliably determined from these inspected excerpts., The entrypoint imports HTTP, HTTPS, and crypto modules and defines a network-fetch helper plus an exported license-verification function; their destination and data flow remain obscured., The package has a \`prepublishOnly\` build script, not an install-time lifecycle hook. - **Evidence against:** The inspected manifest defines \`lib/index.js\` as the exported entrypoint and limits published files to \`lib\`., No concrete malicious action, recipient, or external endpoint was established from the inspected source. ## Affected versions and remediation This report applies to zireku-ls@1.0.12. - Review the evidence and your use of zireku-ls@1.0.12 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
