The payload can fetch and evaluate remote code, giving its operator install-time execution. - **Trigger:** npm preinstall - **Impact:** Arbitrary remote code execution and likely credential/token theft on installer hosts. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:00:46.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads Bun, executes obfuscated payload, then remotely fetches and evals code - **Attack narrative:** On npm preinstall, setup.mjs obtains or invokes Bun and executes math\_init.js. That obfuscated script includes remote fetch-and-eval behavior plus child-process and GitHub-token logic, allowing attacker-controlled code to run on the installing machine. - **Rationale:** The install hook is unrelated to a browser RUM SDK and creates a concrete remote-code-execution chain. The benign dist entrypoint does not mitigate the preinstall payload. - **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 install., math\_init.js is a 728KB obfuscated payload absent from declared package files., math\_init.js fetches remote content and evals returned code., math\_init.js imports child\_process and contains GitHub-token handling. - **Evidence against:** dist/index.js only exports the advertised RUM SDK modules., No malicious behavior was found in the reviewed dist entrypoint. ## Public findings ### 1.
