Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Consumer project data and existing files or directories at those destinations can be lost or overwritten during installation. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 0.0.0-aj-beta.267 - **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 active postinstall performs destructive writes outside the package directory by deleting consumer project directories and replacing root-level paths. This concrete automatic behavior warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-11T10:03:14.357Z - **Finished:** 2026-10-11T10:03:56.800Z - **Download time:** 1023 ms - **Static scan time:** 1101 ms - **AI review time:** 40318 ms - **Total time:** 42443 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 postinstall deletes consumer project directories and replaces root-level paths with package files. This is an automatic destructive mutation of the consuming project. - **Trigger:** Installing the package through npm runs its postinstall hook. - **Impact:** Consumer project data and existing files or directories at those destinations can be lost or overwritten during installation. - **Evidence paths:** package.json, npm-post-install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T10:03:56.800Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer resolves paths above its package directory, recursively removes build, dist, and temp, then removes destinations and renames package contents into the consumer root. - **Attack narrative:** During npm installation, the postinstall hook runs npm-post-install.js. Its path calculations target the consumer project root: it recursively deletes build, dist, and temp, then removes destination paths and moves package content such as .vscode, project, and workspace into the root. This can destroy or replace consumer project data without a separate user action. - **Rationale:** The active postinstall performs destructive writes outside the package directory by deleting consumer project directories and replacing root-level paths. This concrete automatic behavior warrants blocking publication. - **Files touched:** package.json, npm-post-install.js, consumer-root build, consumer-root dist, consumer-root temp, consumer-root .vscode, consumer-root project, consumer-root workspace ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically loads npm-post-install.js during postinstall., The installer resolves project paths above the package directory and recursively deletes build, dist, and temp directories., The postinstall then removes consumer-root destinations and moves package files and directories into those locations, including .vscode, project, and workspace. - **Evidence against:** The package contains no declared dependencies. ## Affected versions and remediation This report applies to @aj-shadow/actorjs-app@0.0.0-aj-beta.267. - Avoid installing @aj-shadow/actorjs-app@0.0.0-aj-beta.267. 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.
