The preinstall bootstrap downloads/uses Bun solely to execute that payload. - **Trigger:** npm installation (preinstall) - **Impact:** npm, GitHub, and AWS credentials may be collected and exfiltrated. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:13:37.308Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads a runtime then executes obfuscated local credential-collection code - **Attack narrative:** On npm preinstall, setup.mjs checks for Bun; if absent it downloads a platform Bun archive, extracts it, and executes math\_init.js. That large obfuscated payload contains collectors for npm tokens, GitHub tokens, and AWS credentials plus filesystem, process, DNS, HTTP, HTTPS, OS, and cryptography access. This is unrelated to the published acquisition-functions library in dist/ and creates an unconsented install-time credential-exfiltration chain. - **Rationale:** The lifecycle chain concretely executes a concealed credential-oriented network payload at install time. Its behavior is unrelated to the package’s stated library functionality. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/\.zip ### 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\` as preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js during install., math\_init.js is a 728KB obfuscated executable payload, absent from the advertised dist-only package files., math\_init.js contains credential handlers for npm tokens, GitHub tokens, and AWS access keys/secrets., math\_init.js imports fs, child\_process, http/https, dns, crypto, and os, consistent with collection and transmission. - **Evidence against:** dist/ contains the stated MongoDB acquisition-function library and no related runtime payload. ## Public findings ### 1.
