MEDIUM

Why flagged The PKGBUILD downloads a prebuilt x86_64 binary (OurGalaxy_Linux.zip) from otherwise.com, which is not an official distribution channel recognized by any major software registry. The binary is extracted and installed to /opt with execute permissions set explicitly. While a sha256sum is provided (providing integrity against accidental corruption or CDN tampering), it does not protect against the upstream host serving a malicious binary from the start, nor does it provide any code transparency. The host 'otherwise.com' appears to be a personal or small-vendor site rather than an established software distribution platform. Installing an opaque prebuilt binary from such a host constitutes a genuine supply-chain risk: if the host is compromised or the maintainer is malicious, arbitrary code executes on the user's system. This is a textbook medium-severity AUR concern — not clearly malicious, but a real supply-chain risk due to an executed binary from an unofficial/personal host with no source code available for review.
