Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Running the mt-tech CLI imports a bundled, obfuscated guard that alters HTTP handling and launches a recurring daemon. The daemon checks for remote updates and can process downloaded files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-28T04:18:06.319Z - **Finished:** 2026-09-28T04:19:26.862Z - **Download time:** 511 ms - **Static scan time:** 339 ms - **AI review time:** 79691 ms - **Total time:** 80543 ms The recorded confidence comes from the underlying analysis.

The daemon checks for remote updates and can process downloaded files. - **Trigger:** A user runs the mt-tech command. - **Impact:** The package can persist outside the requested CLI operation and alter network behavior in the invoking process. - **Evidence paths:** package.json, bin/run.js, node\_modules/@sec/cliguard/index.js, node\_modules/@sec/cliguard/core/cliguard-wrapper.js, node\_modules/@sec/cliguard/core/cliguard.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T04:19:26.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher imports CLIGuard at startup; the guard hooks HTTP requests, starts a background daemon, and polls for updates. - **Attack narrative:** The CLI silently imports an obfuscated bundled dependency before command execution. That dependency hooks HTTP requests, starts a persistent daemon, polls for updates, and contains child-process execution support. These unrelated, concealed behaviors create an active persistence and network-control surface. - **Rationale:** The hidden import-time request interception, recurring daemon, and remote update mechanism are unrelated to a general CLI and are concealed by obfuscation. This is concrete malicious persistence behavior. - **Files touched:** package.json, bin/run.js, node\_modules/@sec/cliguard/index.js, node\_modules/@sec/cliguard/core/cliguard-wrapper.js, node\_modules/@sec/cliguard/core/cliguard.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares the bundled CLIGuard dependency., The CLI imports CLIGuard before executing any command., CLIGuard replaces the process HTTP request function during import., Its wrapper fetches versioned update data and processes a file list., The wrapper starts a daemon that repeatedly runs work every 30 minutes., The bundled guard code is deliberately obfuscated and includes child-process execution support. ## Affected versions and remediation This report applies to mt-tech@1.0.12. - Avoid installing mt-tech@1.0.12. 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.
