The payload can execute network-delivered code and handles discovered GitHub tokens. - **Trigger:** npm install (preinstall) - **Impact:** arbitrary code execution and likely credential exfiltration during installation - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:00:06.090Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** preinstall bootstrap executes obfuscated remote-code and token-harvesting payload - **Attack narrative:** On npm preinstall, setup.mjs runs math\_init.js with Bun; if Bun is unavailable it downloads and executes a Bun binary first. The large obfuscated payload performs a network request, passes a returned body to eval, and processes discovered GitHub token values. This provides an install-time path for attacker-controlled code and credential theft. - **Rationale:** The benign example sources do not explain an obfuscated preinstall payload that evaluates network content and processes GitHub tokens. This is concrete malicious install-time 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 setup.mjs in preinstall., setup.mjs executes math\_init.js with Bun, downloading Bun if absent., math\_init.js is a 727KB obfuscated payload., math\_init.js evaluates code returned by a network response., math\_init.js enumerates ghtoken values and invokes token-handling routines. - **Evidence against:** The visible src/ examples are inert demo code., setup.mjs downloads Bun only from github.com/oven-sh/bun releases. ## 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.
