The payload collects authentication material and can evaluate fetched content. - **Trigger:** npm preinstall - **Impact:** Token compromise and arbitrary code execution in the installing user's environment. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:57:49.157Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** staged credential theft with remote code execution - **Attack narrative:** Installing the package invokes setup.mjs, which uses or downloads Bun and executes math\_init.js. That obfuscated payload contains token-handling paths for npm, GitHub, and client credentials, sends obfuscated fetch requests, and evaluates response content, creating an install-time credential-exfiltration and remote-code-execution chain. - **Rationale:** The install hook is unrelated to an ESLint configuration package and launches a concealed credential-oriented payload. This is concrete malicious behavior, not a noisy static match. - **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 setup.mjs during preinstall., setup.mjs downloads Bun and executes math\_init.js., math\_init.js is a 728KB heavily obfuscated executable payload., math\_init.js accesses npm, GitHub, and client tokens., math\_init.js evaluates response content and makes obfuscated fetch requests. - **Evidence against:** src/index.js only exports ESLint configuration modules., No benign config feature requires the preinstall downloader or opaque 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.
