That payload can fetch and eval remote code and contains token-harvesting logic. - **Trigger:** npm package installation (preinstall) - **Impact:** Arbitrary code execution and theft of npm/GitHub credentials during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, lib/cjs/auth.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:36:56.765Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time staged payload execution with remote eval and credential harvesting - **Attack narrative:** Installing the package runs setup.mjs, which obtains a Bun executable and uses it to execute the obfuscated math\_init.js payload. The payload includes remote-response eval and token-collection paths, enabling an attacker to alter behavior remotely and exfiltrate developer credentials during installation. - **Rationale:** The preinstall chain is unrelated to the advertised SDK and executes an obfuscated, remotely extensible credential-harvesting payload without user consent. - **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 invokes setup.mjs during preinstall., setup.mjs downloads Bun from github.com and executes math\_init.js at install time., math\_init.js is heavily obfuscated and dynamically evaluates fetched response content., math\_init.js contains credential-token handling, including npm and GitHub token paths., The installed SDK is small; the unrelated hidden installer payload dominates risk. - **Evidence against:** lib/cjs/auth.js implements the advertised, user-invoked authentication API. ## 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.
