Why flagged

The PKGBUILD downloads a prebuilt binary .deb from web.qalvpn.com (the vendor's own subdomain, not a third-party host), extracts it with ar/tar, and installs it directly. This is a standard pattern for proprietary software distributed as .deb files in the AUR. The host appears to be the official vendor domain (qalvpn.com), so it is not a random personal or unofficial host. However, the integrity check uses only MD5 (cryptographically broken, no SHA256/b2), there is no GPG signature verification, and the installed artifact is a closed-source prebuilt binary with no way to audit its contents. This constitutes a real supply-chain concern: if the vendor's server is compromised or the binary is silently updated, users receive unverified executable code. The risk is genuine but not clearly malicious — it is the standard medium-risk pattern for unverified prebuilt proprietary binaries from a vendor host.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
