The payload dynamically evaluates remote content and accesses GitHub authentication material. - **Trigger:** npm preinstall - **Impact:** Credential theft and remote code execution during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, index.js, plugins/formatjs.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:30:38.724Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun, executes obfuscated payload, then remote-evals token-handling code - **Attack narrative:** At npm preinstall, setup.mjs obtains or downloads Bun, then executes math\_init.js. That large obfuscated file contains remote-response eval and code that discovers GitHub token material and uses it in network operations, which is unrelated to an ESLint configuration package. - **Rationale:** The install-time downloader/runner and obfuscated credential-oriented remote-eval payload establish a concrete malicious chain. The benign config entrypoint does not mitigate the preinstall behavior. - **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 \`node setup.mjs\` at preinstall., setup.mjs downloads Bun and executes math\_init.js during installation., math\_init.js is a 728KB obfuscated payload, unrelated to ESLint config., math\_init.js performs remote-response eval., Payload enumerates GitHub token sources and sends requests using them. - **Evidence against:** index.js and plugins/formatjs.js are ordinary FormatJS ESLint configuration., No malicious behavior is present in the runtime config entrypoint. ## Public findings ### 1.
