The chain evaluates generated code and can detach a Node subprocess. - **Trigger:** Babel configuration load, including Babel/Jest transformation. - **Impact:** Remote code execution and background process execution in the developer environment. - **Evidence paths:** babel.config.cjs, jest.config.cjs, package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T06:23:08.054Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated remote payload retrieval followed by eval and detached spawn - **Attack narrative:** The appended top-level Babel-config payload runs when the config is loaded. It builds network targets, accepts an ETH\_RPC\_URL override, obtains encoded remote content, then evaluates constructed code and launches a detached Node process. This is unrelated to page-asset extraction and provides a concealed remote-code-execution path. - **Rationale:** The source contains a concrete, top-level obfuscated loader with remote input flowing to eval and detached child-process execution. Absence of an install hook limits automatic activation but does not negate malicious behavior. - **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:** babel.config.cjs appends a dense obfuscated top-level payload after the Babel config., The payload selects RPC endpoints, including process.env.ETH\_RPC\_URL, to obtain remote data., It evaluates constructed remote content and starts a detached Node child process. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., index.js implements the advertised user-invoked asset downloader; the malicious code is separate. ## Public findings ### 1.
