Why flagged

This PKGBUILD downloads a prebuilt binary package (rudesktop-2.9.1069-x86_64.pkg.tar.zst) from storage.rudesktop.ru, which is the vendor's own storage host rather than a well-known, independently auditable source. The package installs an executable binary (usr/bin/rudesktop), a shared library (libsciter-gtk.so), and a systemd service — all of which execute with system privileges. The sha256sum provides integrity against accidental corruption but not against a malicious or compromised vendor host serving a backdoored binary. The maintainer email matches the vendor domain (rudesktop.ru), suggesting this is the upstream vendor packaging their own proprietary software, which is a common AUR pattern, but the binary is still opaque and unauditable. The combination of a prebuilt binary + shared library + systemd service from a single non-mainstream vendor host constitutes a genuine supply-chain risk: if storage.rudesktop.ru is compromised or the vendor is malicious, arbitrary code runs on the user's system. This is a textbook medium-severity supply-chain concern.
