The payload includes token handling and remote-code evaluation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-04T11:19:39.667Z - **Finished:** 2026-08-04T11:20:13.216Z - **Download time:** 512 ms - **Static scan time:** 356 ms - **AI review time:** 32681 ms - **Total time:** 33549 ms ## Security analysis ### Published attack-surface review - **Summary:** npm install runs an obfuscated staged payload. The payload includes token handling and remote-code evaluation. - **Trigger:** npm install (preinstall) - **Impact:** Credential theft and attacker-controlled code execution during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, jest-preset.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:20:13.216Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun and executes obfuscated credential-harvesting payload - **Attack narrative:** The preinstall hook runs setup.mjs, which fetches a Bun binary, writes it to a temporary directory, and uses it to execute the bundled obfuscated math\_init.js. That payload contains npm and GitHub token handling plus evaluation of fetched response content, establishing an install-time credential-exfiltration and remote-code-execution chain unrelated to the declared Jest-config package. - **Rationale:** Concrete source behavior establishes malicious install-time staged execution and credential-focused payload logic. The advertised entrypoint provides no functional configuration and instead throws a migration error. - **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 at preinstall., setup.mjs downloads Bun then executes math\_init.js., math\_init.js is a 728KB obfuscated payload., math\_init.js handles npm/GitHub tokens and evaluates fetched code., Main entry only throws migration error; installer behavior is unrelated. - **Evidence against:** No legitimate Jest configuration is exported by jest-preset.js. ## 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.
