The payload includes remote code evaluation and credential-oriented logic. - **Trigger:** npm preinstall - **Impact:** Arbitrary code execution and potential credential/data exfiltration during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:27:58.931Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun and executes obfuscated remote-capable payload - **Attack narrative:** The preinstall hook invokes setup.mjs. If Bun is absent, it downloads a Bun release, extracts it to a temporary directory, and executes math\_init.js with it. math\_init.js is heavily obfuscated and contains remote-response eval, child-process invocation, and token/credential handling, creating an install-time remote-code and exfiltration chain unrelated to an ESLint config. - **Rationale:** This package’s declared ESLint role does not justify an obfuscated install-time runtime bootstrap or payload execution. Source establishes a concrete malicious execution chain. - **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 preinstall: node setup.mjs., setup.mjs downloads Bun then executes math\_init.js during install., math\_init.js is 727 KB obfuscated payload with remote-response eval., math\_init.js contains credential/token handling and child\_process use. - **Evidence against:** Normal ESLint configuration entrypoints are present., No malicious behavior was found in the readable rule/config modules. ## 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.
