Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary code can run outside the intended asset-extraction functionality and persist as a detached process. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.2.16 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete, obfuscated remote-code loader with an explicit eval and detached process launch. Although it is not install-time, its execution through the package test path is malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-31T06:19:58.901Z - **Finished:** 2026-08-31T06:21:08.552Z - **Download time:** 251 ms - **Static scan time:** 88 ms - **AI review time:** 69312 ms - **Total time:** 69651 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A hidden payload runs when Babel loads babel.config.cjs during JavaScript test transformation. It retrieves remote payload data through blockchain and RPC services, then evaluates it and launches it in a detached Node process. - **Trigger:** Running the package test command or another Babel-based JavaScript transform that loads babel.config.cjs. - **Impact:** Arbitrary code can run outside the intended asset-extraction functionality and persist as a detached process. - **Evidence paths:** babel.config.cjs, jest.config.cjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:21:08.552Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval followed by eval and detached child-process execution. - **Attack narrative:** The package disguises a long obfuscated loader as trailing content in its Babel configuration. The declared Jest setup uses babel-jest for JavaScript transforms, causing that configuration to load during tests. The loader queries blockchain or RPC services to derive a destination, requests encoded payload content, builds code from it, calls eval, and also spawns detached Node with the generated code. This is unrelated to fetching page assets and provides remote code execution. - **Rationale:** This is a concrete, obfuscated remote-code loader with an explicit eval and detached process launch. Although it is not install-time, its execution through the package test path is malicious. - **Files touched:** babel.config.cjs - **Network endpoints:** https://ethereum-rpc.publicnode.com, https://1rpc.io/eth ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** babel.config.cjs appends a large obfuscated program after the Babel configuration., The hidden program locates a blockchain-derived address, fetches an encoded payload, evaluates it, and starts a detached Node process., The test setup routes JavaScript through babel-jest, so running the declared test command loads the malicious Babel configuration. - **Evidence against:** package.json has no install or postinstall lifecycle hook., The published asset-extraction module is separate from the hidden Babel configuration payload. ## Affected versions and remediation This report applies to fetch-page-assets@1.2.16. - Avoid installing fetch-page-assets@1.2.16. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
