The payload includes remote code evaluation and credential/token collection logic. - **Trigger:** Installing @servicetitan/anvil-react@0.11.6 - **Impact:** Arbitrary attacker-supplied code can run with installer permissions and exfiltrate discovered credentials. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:23:11.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** preinstall-launched obfuscated credential-harvesting remote-code loader - **Attack narrative:** Installation triggers setup.mjs. It either invokes an existing Bun executable or downloads Bun from GitHub, then runs math\_init.js. That large obfuscated payload automatically runs, fetches remote content, evaluates returned code, discovers credential sources, and processes GitHub tokens for outbound handling. - **Rationale:** This is concrete install-time execution of an obfuscated credential-oriented remote-code payload, not functionality aligned with a React component library. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** github.com ### 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 and executes \`math\_init.js\` during install., math\_init.js is a 728 KB obfuscated payload, unrelated to the React distribution., math\_init.js invokes remote fetch and evals returned code., Payload logic enumerates credential sources and handles GitHub tokens. - **Evidence against:** dist/ contains normal React UI component exports., The only unobfuscated download endpoint is a Bun GitHub release. ## Public findings ### 1.
