The payload harvests credential material and transmits it over network requests. - **Trigger:** Installing rwc-client@0.29.19 with npm lifecycle scripts enabled. - **Impact:** Compromise of developer credentials or tokens available to the installing user. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:37:01.491Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated install-time credential harvesting and HTTP exfiltration. - **Attack narrative:** The preinstall hook invokes setup.mjs, which obtains a Bun executable if absent and runs the bundled obfuscated math\_init.js. That payload uses filesystem, OS, child-process, token discovery, and fetch-based chunked POST logic; its token handlers explicitly reference GitHub-token forms. This is unrelated to the advertised browser chat client and executes before user code. - **Rationale:** Source inspection confirms a concrete install-time bootstrapper for an obfuscated credential-harvesting/exfiltration payload. This is malicious behavior, not a package-aligned build dependency. - **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 from GitHub and executes math\_init.js during install., math\_init.js is a 728 KB obfuscated executable payload, not chat-client code., math\_init.js imports child\_process, fs, os, and contains credential-token handlers (\`ghtoken\`, \`ghs\_old\`, \`ghs\_jwt\`)., The payload enumerates credential candidates and sends data in HTTP POST chunks via fetch., Install errors are caught and suppressed after payload execution. - **Evidence against:** The runtime dist bundle appears to be a OneReach Vue chat client., No AI-agent control-surface mutation was identified. ## Public findings ### 1.
