The payload can obtain and execute a runtime, collect credentials, and send data to remote services. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-04T11:55:05.676Z - **Finished:** 2026-08-04T11:55:30.917Z - **Download time:** 767 ms - **Static scan time:** 445 ms - **AI review time:** 24028 ms - **Total time:** 25241 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package invokes an obfuscated payload through preinstall. The payload can obtain and execute a runtime, collect credentials, and send data to remote services. - **Trigger:** npm install/preinstall - **Impact:** Credential theft and arbitrary remote code execution during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:55:30.917Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated credential-harvesting payload with remote eval - **Attack narrative:** The preinstall hook runs setup.mjs, which either invokes Bun or downloads it from GitHub and executes math\_init.js. That obfuscated payload contains network fetches whose response is passed to eval, gathers token-bearing credential sources, and uploads collected information. This is unrelated to ESLint configuration and executes without user action during installation. - **Rationale:** This is a concrete install-time execution and credential-exfiltration chain, not a scanner-only inference. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node setup.mjs\` in preinstall., setup.mjs downloads Bun from github.com and executes math\_init.js., math\_init.js is heavily obfuscated and contains fetched-content eval., math\_init.js enumerates credential-bearing sources including GitHub tokens and uploads data. - **Evidence against:** dist/ and src/ are conventional ESLint configuration sources., The declared package purpose does not require a lifecycle downloader or credential handling. ## 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.
