MEDIUM

Why flagged The package downloads a prebuilt binary .deb from 'corp.hosted-by-files.com', which is not the official ExpanDrive distribution host (expandrive.com). This is a third-party/CDN-style host that is not verifiably controlled by the ExpanDrive vendor. A prebuilt binary executed on the user's system from an unofficial host constitutes a genuine supply-chain risk — if the host is compromised or the file is substituted, arbitrary code runs as the user. The sha256sum provides some integrity protection against in-transit tampering, but does not guarantee the binary was originally sourced from the legitimate vendor. The pattern is consistent with a maintainer using a personal or corporate file-hosting service rather than the official vendor download URL, which is a real (if not clearly malicious) supply-chain concern. Medium severity is appropriate.
