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. Importing the package executes its bundled entrypoint. From 2027 onward it deliberately throws, denying normal package use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-09T16:34:16.298Z - **Finished:** 2026-08-09T16:36:14.937Z - **Download time:** 502 ms - **Static scan time:** 153 ms - **AI review time:** 117983 ms - **Total time:** 118639 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:** Importing the package executes its bundled entrypoint. From 2027 onward it deliberately throws, denying normal package use. - **Trigger:** Runtime import or loading of dist/index.obf.js on or after 2027. - **Impact:** Applications using the package fail at runtime after the cutoff. - **Evidence paths:** package.json, dist/index.obf.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T16:36:14.937Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated date-triggered denial-of-service throw. - **Rationale:** The obfuscated import-time date bomb is an intentional availability attack, unsupported by the ISC metadata or README. Absence of exfiltration does not mitigate the runtime denial of service. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** package.json, dist/index.obf.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** dist/index.obf.js ends with a hidden year check and throw., The check is \`getFullYear() \> 0x7ea\` (2026), causing failure from 2027., package.json makes this obfuscated bundle the main/module entrypoint. - **Evidence against:** package.json has no lifecycle hooks or bin., No Node filesystem, process, child-process, credential, or exfiltration behavior found., CDN loading is limited to user-invoked CodeMirror editor assets. ## Affected versions and remediation This report applies to @tomaso909/jsguitools@1.6.0. - Review the evidence and your use of @tomaso909/jsguitools@1.6.0 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.
