Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected source shows package-aligned build setup and local browser discovery, with no confirmed attack surface. The required PDF could not be inspected or cited, so clean citation coverage is incomplete. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-07T02:20:46.614Z - **Finished:** 2026-10-07T02:21:27.960Z - **Download time:** 1283 ms - **Static scan time:** 96 ms - **AI review time:** 39966 ms - **Total time:** 41346 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 behavior was identified in the inspected source. The postinstall hook seeds project build configuration, but the required PDF asset remains uninspected. - **Trigger:** Package installation triggers the postinstall hook; the Playwright installer runs only when invoked directly. - **Impact:** No malicious impact is established from the inspected source; the unreadable required asset prevents a clean determination. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T02:21:27.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies named configuration and pipeline files into the project. The inspected Playwright source searches for local Chromium binaries. - **Rationale:** The inspected source shows package-aligned build setup and local browser discovery, with no confirmed attack surface. The required PDF could not be inspected or cited, so clean citation coverage is incomplete. - **Files touched:** package.json, src/postinstall.js, src/playwright.js, assets/image/jews-support-a-free-palestine-poster.pdf ### Review decision - **Verdict:** Manual Review - **Confidence:** 76.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest runs src/postinstall.js after installation; that script seeds project configuration files and skips the batch when any already exist., The Playwright module only discovers a local Chromium executable and returns it as a launch option., The required PDF asset could not be inspected or cited: the package inspection tool rejected it as a binary or NUL-containing source file. - **Evidence against:** The inspected install hook copies named build configuration and pipeline files; it does not show writes to an AI-agent control surface., The Playwright installer invokes npx playwright install chromium only when its CLI file is run directly. ## Affected versions and remediation This report applies to @doikayt/typescript-build-config@0.1.37. - Review the evidence and your use of @doikayt/typescript-build-config@0.1.37 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node src/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node src/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** src/pipeline/auto-changeset.sh - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = src/pipeline/auto-changeset.sh kind = build_helper sizeBytes = 3136 magicHex = [redacted] ``` ### 8. High: Ships High Entropy Blob - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** assets/image/jews-support-a-free-palestine-poster.pdf - **Public source:** [View source]() Package ships high-entropy non-source blobs. Public source snippet (untrusted): ```text path = assets/image/jews-support-a-free-palestine-poster.pdf kind = high_entropy_blob sizeBytes = 1040003 magicHex = [redacted] ``` ### 9. 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. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 76.0% - **Path:** package.json - **Public source:** [View source]() The manifest runs src/postinstall.js after installation; that script seeds project configuration files and skips the batch when any already exist. Public source snippet (untrusted): ```json "scripts": { "prepack": "echo no build step required", "postinstall": "node src/postinstall.js", "update-all-format" ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 76.0% - **Path:** src/playwright.js - **Public source:** [View source]() The Playwright module only discovers a local Chromium executable and returns it as a launch option. Public source snippet (untrusted): ```javascript for (const cmd of ["chromium", "chromium-browser"]) { try { const p = execSync(`which ${cmd}`, { encoding: "utf8" }).trim(); if (p) return { executablePath: p }; } catch { ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 4 - **Optional dependencies:** 0 - **Peer dependencies:** 3 - **Development dependencies:** 3 - **Published dependency-graph edges:** 7 ### Published dependency entries - @typescript-eslint/eslint-plugin ^8.57.1 (Dependency) - @typescript-eslint/parser ^8.57.1 (Dependency) - eslint ^9.0.0 (Dependency) - prettier ^3.0.0 (Dependency) - @playwright/test \>=1.40.0 (PeerDependency) - @typescript-eslint/eslint-plugin ^8.57.1 (PeerDependency) - @typescript-eslint/parser ^8.57.1 (PeerDependency) ## Package metadata - **Package:** @doikayt/typescript-build-config - **Ecosystem:** npm - **Version:** 0.1.37 - **License:** MIT - **Version published:** 2026-10-06T23:50:53.856Z - **Package first seen:** 2026-07-27T08:18:40.166Z - **Package last seen:** 2026-10-19T04:31:37.427Z - **Known versions:** 32 - **Latest version:** 0.1.55 - **Appeal under review:** No - **Description:** Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets - **Maintainers:** datalackey, lastliet - **Keywords:** eslint, typescript, config, build, tooling, playwright - **Runtime engines:** node: \>=22 - **Artifact files:** 42 - **Artifact unpacked size:** 5,257,394 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]()
