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 hardhat-zet evaluates index.js, which loads an obfuscated lib/config.js payload. That payload pulls in child\_process and can run a hidden execSync command, and it also contains code that fingerprints the host and posts those details with axios. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-26T16:49:50.642Z - **Finished:** 2026-09-26T16:52:04.897Z - **Download time:** 506 ms - **Static scan time:** 2104 ms - **AI review time:** 131644 ms - **Total time:** 134255 ms The recorded confidence comes from the underlying analysis.

That payload pulls in child\_process and can run a hidden execSync command, and it also contains code that fingerprints the host and posts those details with axios. - **Trigger:** Any import or node load of the package main entry index.js. - **Impact:** A consumer process can execute an attacker-controlled command and expose host identity. The exact command text and destination stay hidden by the obfuscation. - **Evidence paths:** package.json, index.js, lib/config.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T16:52:04.897Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** lib/config.js runs on load, decodes strings, requires system modules, fingerprints the machine, and calls execSync under an obfuscated platform check. A separate helper posts host, username, and message data and can require a module from the reply. - **Attack narrative:** hardhat-zet presents itself as a logger, but its entry file loads lib/config.js as soon as the package is imported. That file is a multi-megabyte obfuscated loader. On load it requires operating-system, filesystem, and child-process APIs, records hostname and username, and in a platform check calls execSync on a decoded command. The same file also contains an axios routine that sends host, user, and message fields and can load a module from the response. No install hook is required; importing the package is enough to reach the loader. - **Rationale:** Importing the package runs an obfuscated loader that shells out through execSync and prepares host and username collection plus an axios send. That is concrete remote command execution hidden behind a logger-shaped entry, not ordinary package behavior. ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package entry index.js is evaluated on import and immediately loads lib/config.js while also importing child\_process., lib/config.js is a large obfuscated script that, during that load, requires fs, os, path, and child\_process execSync and spawn, and registers process event handlers., The same load path builds a fingerprint with hostname, operating system, and username through the os module., A nested import-time branch calls execSync on a fully obfuscated command when a decoded platform and release check matches., An axios helper in that file builds a body containing host, os, username, message, level, and data and can require a decoded module from the response. - **Evidence against:** package.json defines no preinstall, install, or postinstall script., The exported middleware in index.js only calls next and does not itself send data., The axios helper name appears only at its definition, so that send path is not shown as a direct call. ## Affected versions and remediation This report applies to hardhat-zet@2.0.1. - Avoid installing hardhat-zet@2.0.1. 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.
