Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package starts a detached loader. That loader fetches attacker-controlled code and executes it with require access. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-16T14:05:51.711Z - **Finished:** 2026-09-16T14:06:26.985Z - **Download time:** 506 ms - **Static scan time:** 24 ms - **AI review time:** 34744 ms - **Total time:** 35274 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 starts a detached loader. That loader fetches attacker-controlled code and executes it with require access. - **Trigger:** Importing engin1 through its main entry point. - **Impact:** Remote operators can run arbitrary Node.js code in the importing user's environment. - **Evidence paths:** index.js, init.js, loader.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T14:06:26.985Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload download and dynamic execution. - **Attack narrative:** A normal import calls initialize(), which creates an unreferenced detached Node process running loader.js. The loader retrieves JSON from api.npoint.io, base64-decodes its code field, and passes it to new Function along with require and filesystem-location values. This gives the remote endpoint control of code executed on the consumer machine and leaves a background loader tracked by .pid. - **Rationale:** The package contains an import-time detached remote-code execution chain unrelated to its advertised utility purpose. This is concrete malicious behavior even without an npm lifecycle hook. - **Files touched:** index.js, init.js, loader.js, .pid - **Network endpoints:** https://api.npoint.io/24c25d5f5fcbb0992a4f ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Importing the main module automatically initializes the package., Initialization starts a detached background loader and records its process ID., The loader downloads base64 content from a remote endpoint and executes it with Node module access., The advertised runtime-information purpose does not match the remote-code loader. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No credential collection is present in the inspected source. ## Affected versions and remediation This report applies to engin1@1.3.99. - Avoid installing engin1@1.3.99. 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.
