When the config is executed, it can evaluate fetched content and launch detached Node code. - **Trigger:** Babel configuration execution, including a Babel/Jest transformation workflow such as the package-defined test command. - **Impact:** Arbitrary remote code execution in the developer or CI environment. - **Evidence paths:** babel.config.cjs, package.json, jest.config.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T23:57:48.781Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated network loader invoking eval and detached child-process execution. - **Attack narrative:** A large obfuscated payload is appended to babel.config.cjs, a configuration file normally expected to contain only Babel settings. It initializes HTTP/S clients and a child-process spawn primitive, reads an RPC environment setting, derives remote control data, then evaluates a constructed payload and starts a detached node -e process. The package exposes a Jest test workflow with babel-jest transforms, creating a package-provided route that can load the malicious configuration during development or CI. - **Rationale:** The appended Babel-config payload is unrelated to asset extraction and contains an explicit remote code-execution chain. Absence of install hooks reduces automatic-install exposure but does not negate the concrete malicious execution path. - **Files touched:** babel.config.cjs ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** babel.config.cjs appends a 31KB obfuscated IIFE after the normal Babel export., The appended code imports child\_process.spawn and reads ETH\_RPC\_URL alongside HTTP/S clients., Its remote-response path calls eval and starts detached node -e execution., The package defines npm test and Jest enables babel-jest transforms, providing a plausible config-execution path. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The main entrypoint is a separate asset-downloading implementation and does not import the Babel config. ## Public findings ### 1.
