The installer downloads and executes Bun, which runs code capable of evaluating remotely supplied JavaScript and handling GitHub credentials. - **Trigger:** npm preinstall - **Impact:** Arbitrary code execution and likely GitHub credential exfiltration on the installing host. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:33:21.018Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun to execute obfuscated credential-harvesting remote-code payload - **Attack narrative:** On npm preinstall, setup.mjs obtains Bun if absent, then executes the large obfuscated math\_init.js payload. That payload includes remote-response eval and GitHub token paths, creating an install-time remote code execution and credential-theft chain. - **Rationale:** The lifecycle payload is concrete, concealed, and unrelated to an SSO backend. Its installer-triggered remote execution and credential handling meet the blocking threshold. - **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\` in preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js during install., math\_init.js is a 727KB obfuscated payload with remote-response \`eval\`., math\_init.js imports child\_process and contains GitHub-token handling (\`ghtoken\`, \`ghs\_old\`, \`ghs\_jwt\`). - **Evidence against:** dist/ contains conventional SSO client code, but it is unrelated to the preinstall payload. ## Public findings ### 1.
