It can obtain a Bun runtime, evaluate fetched code, and access developer credentials. - **Trigger:** npm preinstall during dependency installation - **Impact:** Arbitrary code execution and potential GitHub credential exfiltration. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:25:55.311Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload execution with credential harvesting - **Attack narrative:** The preinstall hook invokes setup.mjs, which either runs a local Bun executable or downloads and executes one, then uses it to run the obfuscated math\_init.js. That script contains a fetch-response eval path and GitHub-token handling alongside filesystem and child-process access, forming an unconsented install-time remote-code and credential-theft chain. - **Rationale:** This is not package-aligned SDK behavior: the install hook bootstraps an unpinned executable to run obfuscated code that evaluates fetched content and targets credentials. The concrete preinstall execution chain warrants blocking. - **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 npm preinstall., setup.mjs downloads and executes Bun before running math\_init.js., math\_init.js is heavily obfuscated install-time code., math\_init.js fetches response text and passes it to eval., math\_init.js enumerates GitHub token sources and uses child\_process/fs. - **Evidence against:** dist entrypoints appear to be the declared React/Web SDK artifacts., The visible Bun download host is github.com, but it does not constrain the later payload. ## Public findings ### 1.
