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 lifecycle hook performs unguarded recursive removal and replacement of parent-project files, so installation carries a real destructive risk. The package metadata suggests this is intended app setup, which leaves malicious intent unestablished; warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-18T17:47:14.903Z - **Finished:** 2026-10-18T17:48:30.305Z - **Download time:** 773 ms - **Static scan time:** 1053 ms - **AI review time:** 73575 ms - **Total time:** 75402 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 install hook can overwrite existing files and directories in the parent project. Its app bootstrap purpose is apparent, but the source does not protect existing destination data. - **Trigger:** Installing the package with npm, which invokes its postinstall hook. - **Impact:** Existing project content at those paths can be lost during installation. - **Evidence paths:** package.json, npm-post-install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-18T17:48:30.305Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook recursively removes named destination paths in the parent project and moves bundled files into their place. - **Rationale:** The lifecycle hook performs unguarded recursive removal and replacement of parent-project files, so installation carries a real destructive risk. The package metadata suggests this is intended app setup, which leaves malicious intent unestablished; warn rather than block. - **Files touched:** .vscode, project, workspace, README.md, CHANGELOG.md, contributors.txt, settings.json, main.js, repos.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs npm-post-install.js during postinstall., The installer targets a directory three levels above the package., On npm installs, it moves bundled project files such as project, workspace, and .vscode to that parent directory., Before moving files, it recursively removes existing destination paths, then renames the bundled files into place., The package metadata identifies it as actorjs-app and names actorjs as its app folder, which is consistent with a project bootstrap purpose. - **Evidence against:** The package identity and generated launcher are consistent with bootstrapping the actorjs app, but they do not guard existing destination data from removal. ## Affected versions and remediation This report applies to @aj-shadow/actorjs-app@0.0.0-aj-beta.272. - Review the evidence and your use of @aj-shadow/actorjs-app@0.0.0-aj-beta.272 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.
