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. Direct source inspection confirms concrete malicious behavior, not merely suspicious primitives. The preinstall chain is unrelated to the package's stated ESLint-config purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-04T11:22:10.826Z - **Finished:** 2026-08-04T11:22:34.571Z - **Download time:** 767 ms - **Static scan time:** 381 ms - **AI review time:** 22596 ms - **Total time:** 23745 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:** Installing the package automatically runs an obfuscated secondary payload. The payload includes remote-code evaluation and GitHub credential collection/exfiltration logic. - **Trigger:** npm preinstall - **Impact:** Remote code execution and theft of GitHub credentials from the install environment. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:22:34.571Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun, executes obfuscated payload, evaluates remote content, and harvests credentials - **Attack narrative:** On npm preinstall, setup.mjs obtains or invokes Bun and runs math\_init.js. That obfuscated payload starts immediately, contains request handling that evaluates server-provided content, and contains logic for GitHub token discovery and outbound requests. This is an unconsented install-time credential-stealing remote execution chain unrelated to an ESLint configuration. - **Rationale:** Direct source inspection confirms concrete malicious behavior, not merely suspicious primitives. The preinstall chain is unrelated to the package's stated ESLint-config purpose. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release, temporary Bun download directory - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs \`node setup.mjs\` as preinstall., setup.mjs downloads Bun and executes math\_init.js during installation., math\_init.js is a 728KB obfuscated payload that immediately invokes its main routine., math\_init.js fetches content and evaluates a returned field with eval., Payload enumerates GitHub-token candidates and sends collected data through request logic. - **Evidence against:** index.js is a conventional ESLint configuration., No benign purpose justifies the hidden preinstall downloader and credential-focused payload. ## Affected versions and remediation This report applies to @ornikar/eslint-config-babel-use@13.2.7. - Avoid installing @ornikar/eslint-config-babel-use@13.2.7. 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.
