The lifecycle script downloads a Bun binary and executes math\_init.js, whose code handles GitHub-style tokens and network requests. - **Trigger:** npm install - **Impact:** Potential theft and remote transmission of developer credentials or tokens. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:11:07.221Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** preinstall downloader executing obfuscated credential-harvesting payload - **Attack narrative:** During npm preinstall, setup.mjs obtains Bun if absent and runs math\_init.js. That unrelated, 727 KB obfuscated script uses filesystem, subprocess, temporary-file, token, and network logic; its decoded control flow references GitHub token credential types. This is a concrete install-time execution chain outside the package's stated action-button purpose. - **Rationale:** The malicious preinstall chain executes an obfuscated payload with credential-oriented and network behavior. The legitimate bundled component code does not justify it. - **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 preinstall: node setup.mjs., setup.mjs downloads Bun 1.3.13 then executes math\_init.js at install time., math\_init.js is a 727 KB heavily obfuscated payload, unrelated to an action-button component., math\_init.js imports child\_process and contains credential/token handling including ghtoken, ghs\_old, and ghs\_jwt flows., Payload creates temporary files, runs subprocesses, and performs obfuscated network requests. - **Evidence against:** dist/ and core/ contain the expected Qlik/Nebula action-button implementation., README.md documents normal component installation and use. ## Public findings ### 1.
