It can evaluate fetched content and launch a detached Node process. - **Trigger:** A Babel-based build or test loads babel.config.cjs. - **Impact:** Arbitrary attacker-controlled code can run outside the package's advertised asset-fetching function. - **Evidence paths:** babel.config.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-30T23:30:49.117Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval followed by evaluation and detached process execution. - **Attack narrative:** The package hides a large executable program after an otherwise ordinary Babel configuration. On Babel configuration load, it queries blockchain-related endpoints, derives further request targets, reconstructs content, evaluates it, and launches a detached Node process. This behavior is unrelated to fetching page assets and provides a covert remote code execution path during normal development tooling use. - **Rationale:** The concealed Babel configuration is an import-time payload loader that performs network-driven code execution and detached process launch. Its behavior is unrelated to the declared package purpose, so publication should be blocked. - **Files touched:** babel.config.cjs ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The Babel configuration contains a large obfuscated program unrelated to asset fetching., That program reads an Ethereum RPC environment setting and builds multiple RPC endpoints., It evaluates reconstructed content and starts a detached hidden Node process with supplied code., The obfuscated program runs immediately when the Babel configuration is loaded. - **Evidence against:** The package manifest has no preinstall, install, or postinstall hook., The declared main entry is index.js, whose visible code implements asset downloading. ## Public findings ### 1.
