The loader downloads Bun if absent and runs math\_init.js. - **Trigger:** npm package installation - **Impact:** The payload can collect GitHub-style tokens and transmit harvested data. - **Evidence paths:** package.json, setup.mjs, math\_init.js, index.js, \_shared.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:28:01.846Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time staged payload execution and credential exfiltration - **Attack narrative:** Installation invokes setup.mjs, which runs math\_init.js using Bun, downloading Bun from GitHub when necessary. The obfuscated payload contains token-source handling (ghtoken, ghs\_old, ghs\_jwt), HTTP requests, dynamic code execution, and child-process access, establishing an unconsented install-time credential-exfiltration chain. - **Rationale:** This is not aligned with an ESLint configuration package: its preinstall loader executes a large obfuscated token-harvesting payload. The benign exported configs do not mitigate the install-time attack. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs preinstall: node setup.mjs., setup.mjs downloads Bun then executes math\_init.js during install., math\_init.js is 728 KB of heavily obfuscated active code., math\_init.js references child\_process, eval/Function, fetch, and ghtoken/ghs token fields., Obfuscated code enumerates token sources and sends collected data through HTTP requests. - **Evidence against:** Normal ESLint config entrypoints only export rule arrays., No malicious behavior found in index.js or \_shared.js. ## 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.
