The payload searches for GitHub credentials and transmits collected data using HTTP upload logic. - **Trigger:** npm preinstall - **Impact:** The installer can steal GitHub credentials from the installing machine. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:37:02.954Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads/executes Bun to run obfuscated credential-exfiltration code - **Attack narrative:** npm invokes setup.mjs during preinstall. It runs math\_init.js directly with Bun when available or downloads and executes Bun first. The obfuscated payload enumerates credential sources, explicitly handles GitHub tokens, constructs upload requests, and removes a temporary marker when finished. This behavior is unrelated to the package's example source files. - **Rationale:** Concrete install-time execution leads to an obfuscated payload with credential collection and upload behavior. The benign example sources do not justify this installer 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/executes Bun on install to run math\_init.js., math\_init.js is a 728 KB obfuscated executable payload., math\_init.js enumerates GitHub tokens and sends collected data through HTTP upload logic., Payload runs automatically and suppresses errors/cleans its temporary marker. - **Evidence against:** src/ contains only simple example JS/TS/Vue code., The Bun release URL in setup.mjs is a real package-aligned bootstrap source, but it is unnecessary for this package. ## Public findings ### 1.
