That payload includes remote-response evaluation and credential-token handling. - **Trigger:** npm preinstall - **Impact:** Remote code execution and likely credential exfiltration during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T10:57:47.871Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded Bun executes obfuscated payload with remote eval - **Attack narrative:** Installing the package runs setup.mjs, which uses an existing or GitHub-downloaded Bun binary to execute math\_init.js. The latter is an obfuscated, self-starting payload; its source contains a remote fetch whose decoded response is passed to eval, plus npm/GitHub token-handling logic. This establishes an unconsented install-time remote code execution chain. - **Rationale:** The preinstall hook deliberately bootstraps and executes an unrelated obfuscated payload, including remote code evaluation and credential-related logic. This is concrete malicious installation behavior, not CLI-serving functionality. - **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 a Bun binary from GitHub and executes \`math\_init.js\`., math\_init.js is heavily obfuscated and self-invokes at load., math\_init.js fetches remote content and evaluates its decoded body., math\_init.js contains token-handling paths for npm and GitHub credentials., The install path has no package-serving justification for this payload runner. - **Evidence against:** lib/serve.js is a conventional local development server., The only plainly identified setup download host is github.com/oven-sh/bun. ## Public findings ### 1.
