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. This behavior is unrelated to a Babel preset and is activated automatically at install time. The clear launcher-to-obfuscated-payload chain establishes concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-04T20:08:01.884Z - **Finished:** 2026-08-04T20:08:30.394Z - **Download time:** 514 ms - **Static scan time:** 362 ms - **AI review time:** 27634 ms - **Total time:** 28510 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 unconditionally executes an obfuscated payload. The payload harvests credentials, communicates remotely, and supports fetched-code evaluation. - **Trigger:** npm preinstall - **Impact:** Credential exfiltration and arbitrary code execution during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T20:08:30.394Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** installer-launched credential-harvesting remote-code payload - **Attack narrative:** The preinstall hook launches setup.mjs, which executes the bundled obfuscated math\_init.js through Bun, downloading Bun when needed. The payload includes credential-source discovery, GitHub-token handling, outbound request construction, and eval of fetched content, creating an unconsented install-time exfiltration and remote-code-execution chain. - **Rationale:** This behavior is unrelated to a Babel preset and is activated automatically at install time. The clear launcher-to-obfuscated-payload chain establishes concrete malicious behavior. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release - **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\` at preinstall., setup.mjs executes math\_init.js with Bun, downloading Bun from GitHub if absent., math\_init.js is a 728 KB obfuscated payload with an immediate async entrypoint., math\_init.js discovers credential sources including GitHub tokens., math\_init.js sends collected data and dynamically evals remotely fetched content. - **Evidence against:** index.js is a conventional Babel preset wrapper., The Bun download endpoint in setup.mjs is GitHub's official oven-sh release URL. ## Affected versions and remediation This report applies to @ornikar/babel-preset-react@6.1.13. - Avoid installing @ornikar/babel-preset-react@6.1.13. 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.
