That payload dynamically evaluates fetched code and contains credential/token-harvesting behavior. - **Trigger:** npm preinstall - **Impact:** Arbitrary code execution and potential credential exfiltration during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/cjs/auth.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:33:06.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote runtime bootstrap followed by obfuscated dynamic payload execution - **Attack narrative:** On preinstall, setup.mjs obtains Bun from GitHub if unavailable and uses it to run math\_init.js. The latter is an obfuscated payload containing network fetch followed by eval of the response, plus token/credential and process-handling code. This concealed install-time execution is unrelated to the published OAuth library. - **Rationale:** The functional auth bundle is benign, but the concealed preinstall bootstrap executes an obfuscated dynamically evaluated payload. This is concrete install-time malware behavior. - **Files touched:** package.json, setup.mjs, math\_init.js, temporary Bun download/extraction 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:** package.json runs \`node setup.mjs\` at preinstall., setup.mjs downloads Bun 1.3.13 then executes math\_init.js during install., math\_init.js is heavily obfuscated and contains fetch-response eval., math\_init.js includes credential/token collection and child-process logic. - **Evidence against:** dist/cjs/auth.js is a conventional browser OAuth helper., Runtime auth requests use caller-supplied authHost. ## Public findings ### 1.
