MEDIUM

Why flagged The PKGBUILD downloads a prebuilt x86_64 .deb binary from 'deploy.totallyacdn.com', which is Windscribe's own CDN (totallyacdn.com is a known Windscribe-operated CDN domain used for their official desktop app distribution). However, the checksum is set to 'SKIP', meaning there is no integrity verification of the downloaded binary. This is a real supply-chain concern: even if the host is legitimate, skipping the checksum means a MITM attack, CDN compromise, or silent binary swap would go undetected. The package installs a full VPN client binary with a systemd service and polkit policy (privileged components), so the impact of a tampered binary would be significant. The host itself appears to be the official Windscribe CDN rather than a random personal host, which reduces (but does not eliminate) the risk. The combination of an executed binary with no integrity check warrants a medium rating.
