Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Existing project data in those legacy directories can be irreversibly lost during installation. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 0.24.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The install hook performs an automatic destructive cleanup of legacy project directories without migrating their contents or requiring confirmation. The legacy checks limit its scope, but do not prevent data loss for users upgrading through installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T17:27:12.363Z - **Finished:** 2026-10-21T17:28:23.742Z - **Download time:** 5849 ms - **Static scan time:** 494 ms - **AI review time:** 65035 ms - **Total time:** 71379 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:** A package install can delete data from a consuming project’s recognized legacy DocNexus directories. The cleanup removes those directories without migrating their contents. - **Trigger:** Installing the package locally with npm, which runs its postinstall hook. - **Impact:** Existing project data in those legacy directories can be irreversibly lost during installation. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/src/legacy-cleanup.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T17:28:23.742Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook resolves the consuming project and invokes cleanup that recursively removes directories passing legacy checks. - **Attack narrative:** A local npm installation triggers postinstall cleanup. The cleanup identifies legacy DocNexus directories and removes their contents recursively without migration. This can cause irreversible loss of project data during installation, despite the checks limiting deletion to recognized legacy directories. - **Rationale:** The install hook performs an automatic destructive cleanup of legacy project directories without migrating their contents or requiring confirmation. The legacy checks limit its scope, but do not prevent data loss for users upgrading through installation. - **Files touched:** package.json, scripts/postinstall.mjs, dist/src/legacy-cleanup.js ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall script during package installation., The hook resolves the consuming project and calls legacy cleanup for local installs., Cleanup checks for legacy project directories, then recursively deletes them without migrating their contents., The cleanup routine describes the transition as destructive and removes the legacy workspace directory. - **Evidence against:** Cleanup is limited to directories that pass legacy-format checks; it does not target arbitrary project directories. ## Affected versions and remediation This report applies to @rowansenne/docnexus@0.24.3. - Avoid installing @rowansenne/docnexus@0.24.3. 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.
