It bootstraps Bun if absent and executes code that can evaluate remotely supplied content and harvest credentials. - **Trigger:** npm preinstall - **Impact:** Arbitrary code execution and potential credential exfiltration on the installer machine. - **Evidence paths:** package.json, setup.mjs, math\_init.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:53:18.885Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated credential-harvesting remote-code loader - **Attack narrative:** Installing the package invokes setup.mjs. That hook uses an existing Bun binary or downloads and executes Bun, which runs the obfuscated math\_init.js payload. The payload includes dynamic evaluation of fetched response content and credential/token collection logic, creating an unconsented install-time remote-code-execution and exfiltration path unrelated to the SDK. - **Rationale:** The documented UI SDK is bundled in dist/, but an unrelated preinstall hook bootstraps and executes a large obfuscated payload with remote evaluation and credential-harvesting behavior. This is concrete malicious install-time behavior. - **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.com without integrity verification, then executes math\_init.js., math\_init.js is a 728 KB obfuscated Bun payload executed during installation., math\_init.js dynamically evaluates response content and contains credential/token-harvesting and process-control logic., The install payload is unrelated to the documented React/Verdocs SDK. - **Evidence against:** dist/ and README.md contain the expected Verdocs React SDK artifacts and documentation., No malicious behavior was confirmed in the reviewed SDK entrypoint itself. ## Public findings ### 1.
