Why flagged

This PKGBUILD downloads a prebuilt binary (a Unity-based Linux executable) from the project's own domain (ecity-project.eu), which is the official upstream URL matching the package's stated homepage. The binary is installed to /opt and executed at runtime. While the host is not a major distribution mirror, it is the official project website, not a personal or third-party host. The concern is real but modest: there is no checksum algorithm stronger than MD5 (weak integrity guarantee), and the binary is a closed prebuilt Unity application from a small academic project whose domain could be abandoned or compromised. This fits the medium category — a prebuilt executable from a small/unofficial host with only MD5 verification — but is not clearly malicious.

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, …).
