MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary tarball from updates.torguard.biz, which is TorGuard's own official update infrastructure (not a personal or third-party host). The package installs a closed-source VPN client binary directly into /opt/torguard and symlinks its wrapper into /usr/bin. While the host is the vendor's own update server (a legitimate pattern for proprietary software distributed via AUR), the artifact is a prebuilt executable blob with no source build, and the sha256sum is a single fixed checksum providing only integrity, not authenticity. If the vendor's update server were compromised or the artifact silently replaced with a matching checksum collision, arbitrary code would execute with user/root privileges. This is a standard medium-risk pattern for proprietary binary AUR packages: not clearly malicious, but a real supply-chain concern due to the executed binary from an external host with no GPG signature verification.

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, …).
