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. A normal import starts a detached loader. The loader retrieves and executes attacker-controlled remote JavaScript. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T04:48:04.949Z - **Finished:** 2026-09-14T04:48:54.152Z - **Download time:** 780 ms - **Static scan time:** 18 ms - **AI review time:** 48404 ms - **Total time:** 49203 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 normal import starts a detached loader. The loader retrieves and executes attacker-controlled remote JavaScript. - **Trigger:** Importing @biz44/id12-client, or explicitly loading loader.js. - **Impact:** The endpoint operator can run arbitrary Node.js code in the importing user's environment and leave a background process running. - **Evidence paths:** index.js, init.js, loader.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T04:48:54.152Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload loader using HTTPS, base64 decoding, and Function execution. - **Attack narrative:** When an application imports the package, index.js calls initialize. That function starts loader.js detached with hidden standard streams and writes a PID marker. The loader fetches JSON from api.npoint.io, base64-decodes its code field, and invokes it through Function with Node module loading available. This gives a remote endpoint operator arbitrary code execution in the consumer environment without an explicit user action beyond importing the package. - **Rationale:** The package establishes an import-triggered detached process that fetches and executes remotely supplied code. This is concrete remote code execution and persistence-like behavior, not a transparent package feature. - **Files touched:** index.js, init.js, loader.js, .pid - **Network endpoints:** https://api.npoint.io/24c12c4b66a29747764f ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Importing the main entry immediately initializes the client., Initialization launches loader.js as a detached background Node process and records its PID., The loader downloads a base64 code field from a remote endpoint., The downloaded code is executed with require and module context, enabling remote code execution. - **Evidence against:** package.json has no npm install lifecycle hook., The inspected source does not explicitly collect credentials or upload local data. ## Affected versions and remediation This report applies to @biz44/id12-client@1.1.13. - Avoid installing @biz44/id12-client@1.1.13. 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.
