It seeds GitHub release automation that can publish using the consumer repository's configured npm secret. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-11T04:49:59.083Z - **Finished:** 2026-08-11T04:50:30.830Z - **Download time:** 502 ms - **Static scan time:** 116 ms - **AI review time:** 31128 ms - **Total time:** 31747 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code mutates the consuming project when target files are absent. It seeds GitHub release automation that can publish using the consumer repository's configured npm secret. - **Trigger:** npm installation executes postinstall. - **Impact:** Unconsented modification of a consumer repository and future CI release behavior. - **Evidence paths:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, src/pipeline/auto-changeset.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-11T04:50:30.830Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies project configs, scripts, and CI workflows - **Rationale:** The package's postinstall performs broad consumer-project and CI automation setup without an explicit command. Its release behavior appears package-aligned rather than covert, so this warrants a warning rather than a block. - **Files touched:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, src/pipeline/auto-changeset.sh, .github/workflows/release.yml, .github/workflows/verify-npm-token.yml, .changeset/config.json, scripts/auto-changeset.sh - **Network endpoints:** https://registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs postinstall automatically., src/postinstall.js writes consumer config and CI files., It seeds a release workflow that publishes with NODE\_AUTH\_TOKEN. - **Evidence against:** No credential harvesting or outbound exfiltration found., Workflow targets npm registry and is a conventional release pipeline., Explicit CLI setup paths are user-invoked. ## 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. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @doikayt/typescript-build-config@0.1.21 matchedIdentity = npm:[redacted]:0.1.21 similarity = 0.955 summary = stored previous version shares package body but lacks this dangerous source file ``` ## 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 ^8.0.0 (Dependency) - @typescript-eslint/parser ^8.0.0 (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:** 0.1.28 - **License:** MIT - **Version published:** 2026-08-10T23:53:48.509Z - **Package first seen:** 2026-07-27T08:18:40.166Z - **Package last seen:** 2026-08-11T10:03:54.840Z - **Known versions:** 13 - **Latest version:** 0.1.31 - **Appeal under review:** No - **Description:** Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets - **Maintainers:** datalackey - **Keywords:** eslint, typescript, config, build, tooling, playwright - **Runtime engines:** node: \>=22 - **Artifact files:** 42 - **Artifact unpacked size:** 5,251,593 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
