The payload contains GitHub-token collection/processing logic and process execution. - **Trigger:** Installing the package runs the preinstall lifecycle hook. - **Impact:** Potential theft or misuse of GitHub credentials and arbitrary code execution during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:05:58.726Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time remote runtime download and obfuscated credential-harvesting payload execution - **Attack narrative:** On npm installation, package.json invokes setup.mjs. That script downloads a platform-specific Bun binary from GitHub if Bun is absent, then executes the unrelated, 727KB obfuscated math\_init.js payload. Static inspection of that payload shows child-process execution and GitHub credential-token handling (\`ghtoken\`, \`ghs\_old\`, \`ghs\_jwt\`), while the advertised source and runtime entrypoint are ordinary React utilities and do not use it. - **Rationale:** The concealed preinstall downloader/executor is unrelated to the package’s stated functionality, and the executed payload includes credential-token handling. This is a concrete install-time malicious execution 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 \`node setup.mjs\` as preinstall., setup.mjs downloads Bun 1.3.13 from GitHub and executes math\_init.js during installation., math\_init.js is a 727KB heavily obfuscated executable payload unrelated to the published React utility sources., math\_init.js contains credential-token handling paths including \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\`, plus child\_process use., The legitimate src/ and dist/ entrypoint do not reference the preinstall payload. - **Evidence against:** dist/index.js only exports utility hooks and registry providers., README and src describe a normal cross-MFE React utility API. ## Public findings ### 1.
