The loader evaluates retrieved code and starts a detached Node subprocess. - **Trigger:** Running npm test or another Babel-based workflow that loads babel.config.cjs. - **Impact:** Arbitrary remote code can run on the developer or build machine. - **Evidence paths:** babel.config.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:16:11.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval followed by eval and detached process execution. - **Attack narrative:** The package disguises malicious code after an ordinary Babel configuration export. When Babel loads that file, the payload runs automatically, uses network and blockchain-derived data to locate remote content, reconstructs it, evaluates it, and launches a detached hidden Node process. The Jest setup selects babel-jest, so the package's own test command provides a practical automatic trigger. - **Rationale:** This is a concealed remote-code-execution loader embedded in a build configuration, unrelated to page asset extraction. The absence of an install hook does not neutralize execution through the package's test workflow. - **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 large obfuscated payload that runs when the Babel configuration is loaded., The concealed payload obtains remote content, passes it to eval, and launches a detached hidden Node process., The Jest configuration uses babel-jest, making the malicious Babel configuration load during npm test. - **Evidence against:** package.json defines no preinstall, install, or postinstall lifecycle hook., The advertised asset-fetching entrypoint has network and file writes aligned with its stated purpose when explicitly invoked. ## Public findings ### 1.
