The payload accesses local process/filesystem facilities, handles GitHub credential categories, and performs HTTP(S) operations. - **Trigger:** npm install - **Impact:** Potential theft and misuse of GitHub credentials on the installing host. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:33:28.176Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** preinstall downloader executes obfuscated credential-handling payload - **Attack narrative:** Installation invokes setup.mjs. It executes math\_init.js through Bun if available, otherwise downloads a Bun binary from GitHub and executes the payload. The large obfuscated payload imports process, filesystem, child-process, and HTTP(S) capabilities; its visible control flow collects GitHub-token categories and performs network requests. This is unrelated to a Jest configuration package and creates an unconsented install-time credential-exfiltration chain. - **Rationale:** Concrete install-time execution of an obfuscated credential-oriented network payload is malicious. The normal Jest files do not mitigate that behavior. - **Files touched:** package.json, setup.mjs, math\_init.js - **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\` as preinstall., setup.mjs downloads Bun from GitHub when absent, then executes math\_init.js., math\_init.js is a 728KB heavily obfuscated executable payload., math\_init.js imports child\_process, fs, os, path, http, and https., Payload enumerates \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\` credential categories and sends HTTP requests. - **Evidence against:** Documented Jest entrypoints are ordinary test-configuration helpers., No benign package function explains the preinstall downloader and concealed credential-handling payload. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.preinstall = node setup.mjs ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** math\_init.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L1: // @bun @bun-cjs L2: var MmgoCP,etDiOOB,JqTtnbZ,bc3Kak,ZQmUTyQ,TTUgga,MDX6yrw,h8wMJNB,CabwE2L,x5ErqV;function WV8StW(MmgoCP,etDiOOB,JqTtnbZ){for(JqTtnbZ=0x0;JqTtnbZ) Package ships non-JavaScript build or shell helper files.
