Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The importing process can run attacker-chosen code, spawn shell commands, and send host identity to a remote server. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 2.3.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-16349 identifies this version as malicious. 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 runs packed lib/config.js, which fingerprints the host and uses axios plus Function and execSync to fetch and run extra code. Copied Pino files and a no-op middleware hide that dropper. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-17T21:52:02.848Z - **Finished:** 2026-09-17T21:59:29.653Z - **Download time:** 506 ms - **Static scan time:** 2847 ms - **AI review time:** 443451 ms - **Total time:** 446805 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 runs packed lib/config.js, which fingerprints the host and uses axios plus Function and execSync to fetch and run extra code. Copied Pino files and a no-op middleware hide that dropper. - **Trigger:** Any install or runtime import of hardhat-devkit, including require of index.js. - **Impact:** The importing process can run attacker-chosen code, spawn shell commands, and send host identity to a remote server. - **Evidence paths:** package.json, index.js, lib/config.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T21:59:29.653Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time obfuscated dropper with remote fetch and local command execution - **Attack narrative:** When an app imports hardhat-devkit, index.js immediately requires lib/config.js. That file is packed obfuscated code, not logger setup. It fingerprints host, operating system, and username, posts with axios, builds a Function from decoded text, and runs execSync or spawn. Copied Pino docs and an empty Express middleware hide this import-time dropper. There is no Hardhat or logging reason for that chain. - **Rationale:** Importing the package runs a packed dropper that collects host identity, talks over axios, and executes decoded code with Function and execSync. The Pino-looking docs and empty middleware do not explain that behavior. - **Files touched:** index.js, lib/config.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package is named hardhat-devkit but uses a stolen Pino vulnerability-policy description and logger keywords, not a Hardhat toolkit., index.js loads lib/config.js as soon as the package is imported., lib/config.js is one packed obfuscated line that builds and runs a Function from decoded strings., That loader requires axios and crypto, then posts with a Content-Type and validation header., Top-level code requires os, fs, execSync, and spawn, then calls execSync with concatenated strings., It fingerprints host, operating system, and username into a Utils helper. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., Other lib files still look like leftover Pino logger source and are not the dropper. ## Affected versions and remediation This report applies to hardhat-devkit@2.3.6. - Avoid installing hardhat-devkit@2.3.6. 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.
