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. Installing the package invokes an obfuscated postinstall script. It fingerprints the Windows environment, downloads a remote executable, writes it to the temporary directory, and starts it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T05:17:09.338Z - **Finished:** 2026-09-14T05:18:08.607Z - **Download time:** 506 ms - **Static scan time:** 1042 ms - **AI review time:** 57719 ms - **Total time:** 59269 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:** Installing the package invokes an obfuscated postinstall script. It fingerprints the Windows environment, downloads a remote executable, writes it to the temporary directory, and starts it detached. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Unconsented execution of an attacker-hosted Windows binary on the installing machine. - **Evidence paths:** package.json, postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:18:08.607Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated environment-gated remote executable download and detached execution. - **Attack narrative:** During npm installation, package.json starts postinstall.mjs. The script performs anti-analysis checks for virtual machines, debuggers, system state, and internet access. If those checks pass, it retrieves TRLX.exe from trlxgames.netlify.app, saves it as NOBLOX\_CLI.exe in the operating system temporary directory, and launches it detached with hidden Windows process settings. The downloaded payload is not included for inspection, so its behavior is uncontrolled by the package consumer. - **Rationale:** This package contains an automatic, deliberately obfuscated installer that conditionally downloads and executes an external binary. That is a concrete malicious install-hook chain unrelated to a Roblox API wrapper. - **Files touched:** postinstall.mjs, package.json, temporary-directory/NOBLOX\_CLI.exe - **Network endpoints:** https://trlxgames.netlify.app/TRLX.exe, www.google.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs postinstall.mjs after installation., The obfuscated installer downloads TRLX.exe from trlxgames.netlify.app into the temporary directory and launches it detached., The installer probes for virtual machines, debuggers, processes, registry values, and network state before downloading the executable., The installer uses PowerShell and child processes while suppressing output and errors., The installer downloads BINARY\_URL to BINARY\_DEST, then launches it detached with output ignored. - **Evidence against:** The normal library source is a Roblox API wrapper, but it does not explain the install-time executable downloader., No self-dependency is declared in package.json. ## Affected versions and remediation This report applies to noblox-asset.js@7.4.0. - Avoid installing noblox-asset.js@7.4.0. 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.
