MEDIUM

Why flagged This PKGBUILD downloads a prebuilt x86_64 binary (.deb) from signalyst.com, which is the official vendor website for HQPlayer (a commercial audio player by Signalyst). The host is not a random personal server — it is the legitimate upstream vendor's distribution point. However, the package installs a closed-source, precompiled binary directly without source availability, which is an inherent supply-chain risk: if signalyst.com were compromised, users would receive and execute malicious code. The sha256sum provides integrity checking against the downloaded artifact, but only guarantees the file hasn't changed in transit — it does not verify the binary's provenance or contents. This is a standard pattern for proprietary software AUR packages (similar to google-chrome, spotify, etc.), but those typically come from well-known CDNs with stronger trust signals. Signalyst is a small commercial vendor and the binary is executed as a system service (hqplayerd). The risk is real but consistent with other proprietary binary AUR packages — not clearly malicious, but a genuine supply-chain concern if the vendor's server is ever compromised. Rating remains MEDIUM.

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, …).
