OpenSSF/OSV advisory MAL-2025-49362 confirms this npm version as malicious. At CLI startup, index.js downloads three native shared libraries (sbx.so, bot.so, v1.so) from https://${arch}.31888.xyz/ (amd64.31888.xyz, arm64.31888.xyz), writes them to disk, and loads them via koffi.load() to invoke native functions from the fetched bytes... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-10-21T22:40:08.518Z - **Finished:** 2026-10-21T22:40:08.518Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to snavbox@1.0.1. The same advisory and Firewall decision cover these 2 recorded versions: 1.0.0, 1.0.1. - Avoid installing snavbox@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% At CLI startup, index.js downloads three native shared libraries (sbx.so, bot.so, v1.so) from https://${arch}.31888.xyz/ (amd64.31888.xyz, arm64.31888.xyz), writes them to disk, and loads them via koffi.load() to invoke native functions from the fetched bytes. The download URL is not version-pinned, the domain is unrelated to the package publisher, and the downloadLibrary(url, fileName, expectedSha256) helper treats an empty expectedSha256 as a pass, so no integrity check is performed. Package metadata describes the project as "WildGuard - Protect Our Wildlife" with an accompanying wildlife-themed index.html, but the actual code implements a sing-box multi-protocol proxy (vless/vmess/trojan/hysteria2/tuic/reality/anytls), a Cloudflare Argo tunnel configured with noTLSVerify: true, a Nezha remote-management agent, and a hardcoded keep-alive callback to https://keep.gvrander.eu.org/add-url. Multiple execSync('curl...') invocations are also present. The mismatch between the advertised purpose and the shipped behavior, combined with the unpinned unverified native-code fetch from a non-publisher host, gives the operator of 31888.xyz arbitrary code execution on any host that runs this package. \#\# Source: ghsa-malware (d8c70660a97aff07d3f4c6a0c03af63cceb7fcefdd52b293ef98b0be0ae55df8) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. \#\# Source: ossf-package-analysis (4b16f46f7bce0e06e8afe06d96ba465799db8e470814384124b318b2b98285ff) The OpenSSF Package Analysis project identified 'snavbox' @ 1.0.0 (npm) as malicious. It is considered malicious because: - The package executes one or more commands associated with malicious behavior. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** snavbox - **Ecosystem:** npm - **Version:** 1.0.1 - **Version published:** 2026-01-05T12:22:40.130Z - **Package first seen:** 2026-08-16T16:20:04.791Z - **Package last seen:** 2026-10-21T22:40:35.306Z - **Known versions:** 6 - **Latest version:** 0.0.1-security.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]()
