That payload fetches code for eval and accesses GitHub-token-related credentials. - **Trigger:** npm installation - **Impact:** Install-time arbitrary code execution and potential credential exfiltration. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:25:06.934Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap followed by obfuscated fetched-code execution and credential access - **Attack narrative:** Installation invokes setup.mjs, which either runs an existing Bun or downloads a platform-specific Bun release, then executes math\_init.js. The obfuscated payload contains network fetches, eval of response text, and logic referencing GitHub token credentials, creating an install-time remote-code and credential-theft chain. - **Rationale:** The lifecycle hook’s remote executable bootstrap is unrelated to a Jest preset, and the launched obfuscated payload contains concrete fetched-code eval and token-handling behavior. This is a malicious install-time 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 setup.mjs as preinstall., setup.mjs downloads and executes Bun on install., setup.mjs executes math\_init.js., math\_init.js is heavily obfuscated and calls eval on fetched response text., math\_init.js enumerates GitHub-token-related credentials and performs network requests. - **Evidence against:** jest-preset.js is a conventional Jest/Expo configuration., The manifest’s intended package entrypoint is a Jest preset. ## 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.
