Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.1.33 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Inspected behavior is consistent with TypeScript build tooling, and the scanner's similarity and entropy labels do not establish an attack. The lifecycle self-dependency rule does not apply because the self-reference is development-only and the installer is transparent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-05T04:10:26.108Z - **Finished:** 2026-10-05T04:11:41.391Z - **Download time:** 756 ms - **Static scan time:** 95 ms - **AI review time:** 74430 ms - **Total time:** 75283 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:** No confirmed attack was identified. Installation seeds build and CI configuration, while explicit CLI commands scaffold projects or install Playwright browsers. - **Trigger:** npm installation activates configuration seeding; users invoke the additional CLI operations. - **Impact:** Expected project setup changes occur; no credential theft, remote payload execution, or AI-agent control mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-05T04:11:41.391Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected code copies package templates, preserves existing files, and uses ordinary tooling commands for configuration and browser setup. - **Rationale:** Inspected behavior is consistent with TypeScript build tooling, and the scanner's similarity and entropy labels do not establish an attack. The lifecycle self-dependency rule does not apply because the self-reference is development-only and the installer is transparent. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest activates a transparent build-configuration postinstall hook; its self-dependency is development-only., The install hook preserves existing configuration and seeds missing pipeline files; differences receive a local diff., The Playwright helper locates Chromium using fixed command names and returns its executable path., The PDF contains compressed PDF objects; inspected executable paths do not load or execute it. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.33. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.33 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** src/playwright.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = @doikayt/typescript-build-config@0.1.14 matchedPath = src/playwright.js matchedIdentity = npm:[redacted]:0.1.14 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 11. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/postinstall.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
