AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete import-time remote-code-execution chain, not a normal request helper. The hard-coded network payload is executed without user action or integrity verification. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-12T19:19:38.666Z - **Finished:** 2026-07-12T19:19:59.379Z - **Download time:** 511 ms - **Static scan time:** 28 ms - **AI review time:** 20173 ms - **Total time:** 20713 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:** Importing the package triggers a request to a hard-coded remote endpoint. The returned response supplies JavaScript that is executed with Node's \`require\` capability. - **Trigger:** Any runtime \`require('express-request-engine')\` or import of its main entrypoint. - **Impact:** A remote endpoint can execute arbitrary Node.js code in the consuming application's process. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-12T19:19:59.379Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload retrieval and dynamic code execution - **Attack narrative:** When the main entrypoint loads, it calls \`initPlugin()\` with a hard-coded JsonBin URL. It retrieves JSON, extracts \`record.cerookie\`, constructs a function from that remote string via \`Function.constructor\`, and invokes it with Node's \`require\`. The endpoint operator can therefore choose code executed in every process that imports the package. - **Rationale:** This is a concrete import-time remote-code-execution chain, not a normal request helper. The hard-coded network payload is executed without user action or integrity verification. - **Files touched:** index.js, package.json - **Network endpoints:** https://api.jsonbin.io/v3/b/6a4f5816f5f4af5e29762c92 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`index.js\` runs \`initPlugin()\` immediately on module import., \`index.js\` fetches a hard-coded JsonBin URL by default., \`index.js\` reads \`record.cerookie\` from the network response., \`index.js\` executes that response using \`Function.constructor\` with \`require\` access., \`package.json\` has no lifecycle hook; the malicious path is import-time. - **Evidence against:** No package files beyond \`package.json\` and \`index.js\` are present., No local file harvesting, persistence, or AI-agent configuration writes were found. ## Affected versions and remediation This report applies to express-request-engine@3.6.3. - Avoid installing express-request-engine@3.6.3. 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.
