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. Installing the npm package on Windows downloads an externally hosted executable and starts it automatically. The executable is not pinned or integrity-checked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T18:38:57.915Z - **Finished:** 2026-09-07T18:39:45.563Z - **Download time:** 255 ms - **Static scan time:** 40 ms - **AI review time:** 47352 ms - **Total time:** 47648 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 npm package on Windows downloads an externally hosted executable and starts it automatically. The executable is not pinned or integrity-checked. - **Trigger:** npm installation, which runs the install lifecycle on Windows. - **Impact:** A remotely replaceable executable obtains code execution under the installing user's account. - **Evidence paths:** package.json, bin/xxcf.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T18:39:45.563Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle download-and-execute of an unverified remote executable. - **Attack narrative:** During npm installation, package.json invokes bin/xxcf.js with the install command. On Windows, that code downloads SnowRichSetup.exe from a mutable latest-release URL or a fallback host, checks only that it exceeds 100 KB, and starts it detached. This gives remote executable content code execution during dependency installation without a hash, signature, or explicit installer command from the user. - **Rationale:** This is a concrete automatic install-hook download-and-execute chain, not merely a user-invoked CLI installer. The remote payload is mutable and lacks integrity verification. - **Files touched:** package.json, bin/xxcf.js, SnowRichSetup.exe, SnowRichMT5Bot/xuexue.exe - **Network endpoints:** https://github.com/xxcf2026/xxcf2026/releases/latest/download/SnowRichSetup.exe, https://oss.example.com/xxcf2026/SnowRichSetup.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The install lifecycle automatically invokes the installer command., On Windows, the installer fetches a remote executable from release and fallback URLs., The download accepts a file based only on HTTP success and size, with no integrity or signature verification., The downloaded executable is launched detached during installation. - **Evidence against:** The JavaScript source is readable and contains no credential collection or data-exfiltration logic., The install path is restricted to Windows and the stated executable installer flow. ## Affected versions and remediation This report applies to xxcf2026@1.2.0. - Avoid installing xxcf2026@1.2.0. 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.
