The lifecycle script downloads/executes a runtime when Bun is unavailable, then runs credential-harvesting code. - **Trigger:** npm preinstall - **Impact:** Exposure of GitHub and cloud credentials from the installing machine. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:26:21.459Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated credential-exfiltration payload - **Attack narrative:** npm install invokes setup.mjs. It either executes a locally installed Bun or downloads Bun from GitHub, then uses it to execute math\_init.js. That obfuscated payload runs immediately, references AWS and GitHub token material, and sends collected results through its internal network path while hiding failures. - **Rationale:** This is concrete, unconsented preinstall execution of an obfuscated credential-harvesting payload, not functionality aligned with a React web SDK. - **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.com and executes \`math\_init.js\` during installation., math\_init.js is a 727 KB heavily obfuscated executable payload using dynamic Function/eval., math\_init.js invokes its payload immediately and suppresses errors., Payload references \`.aws\`, \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\`, then submits collected results through internal sender objects. - **Evidence against:** The published React SDK files under dist are not the install-time payload. ## Public findings ### 1.
