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 package on Windows automatically retrieves or stages a PE installer and launches it. The downloaded payload is mutable and not integrity-checked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T18:44:36.161Z - **Finished:** 2026-09-07T18:45:35.383Z - **Download time:** 1010 ms - **Static scan time:** 63 ms - **AI review time:** 58148 ms - **Total time:** 59222 ms The recorded confidence comes from the underlying analysis.

The downloaded payload is mutable and not integrity-checked. - **Trigger:** npm install of the package on Windows - **Impact:** Unconsented execution of an opaque native installer during dependency installation. - **Evidence paths:** package.json, bin/xxcf.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T18:45:35.383Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install hook downloads or stages and detached-launches an executable - **Attack narrative:** The install lifecycle invokes the CLI with the install command. On Windows, that command downloads an executable from a redirectable latest-release URL or copies the bundled PE into the temporary directory, then launches it detached. There is no checksum or signature validation in the JavaScript path, so package installation executes an opaque and mutable native payload without an explicit user command. - **Rationale:** This is a concrete install-hook abuse chain: automatic lifecycle execution fetches or stages a native payload and launches it without integrity verification. The absence of direct credential theft in the wrapper does not neutralize the unconsented opaque payload execution. - **Files touched:** installer/SnowRichSetup.exe, %TEMP%/SnowRichSetup.exe - **Network endpoints:** https://github.com/xxcf2026/xxcf2026/releases/latest/download/SnowRichSetup.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The npm install lifecycle automatically invokes the installer., On Windows, it downloads an executable from a mutable latest-release URL, follows redirects, and performs no integrity verification., It starts the downloaded executable detached and without user interaction., A bundled PE executable is also copied to the temporary installer path as fallback. - **Evidence against:** The JavaScript source does not directly harvest credentials or alter AI-agent configuration., The install path is limited to Windows, but it still runs automatically during npm installation there. ## Affected versions and remediation This report applies to xxcf2026@1.2.1. - Avoid installing xxcf2026@1.2.1. 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.
