That payload searches GitHub-token-related data and sends chunked network requests. - **Trigger:** npm install - **Impact:** GitHub credentials and local environment data may be exposed to an attacker. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:42:32.973Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time staged payload execution and credential harvesting/exfiltration - **Attack narrative:** Installing the package triggers setup.mjs. It obtains or downloads Bun, then executes the large obfuscated math\_init.js payload. Source in that payload accesses filesystem and process facilities, searches GitHub-token-related values, and implements network request and chunked upload behavior. The obfuscation and installer-delivered runtime make the payload's credential-access and outbound transfer behavior stealthy and unconsented. - **Rationale:** This is a concrete preinstall staged-payload chain, not a package-aligned frontend utility. The executed payload contains credential-targeting and outbound transfer logic. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release, temporary Bun download directory - **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\` in preinstall., setup.mjs downloads Bun from GitHub and executes \`math\_init.js\` during install., math\_init.js is a 728 KB heavily obfuscated executable payload., math\_init.js enumerates \`ghtoken\` values and contains upload/chunking logic., Payload imports fs/os/path/child\_process and performs network requests. - **Evidence against:** No legitimate frontend-orb runtime entrypoint is shipped., The only visible external bootstrap endpoint is the Bun release host. ## Public findings ### 1.
