Why flagged

The PKGBUILD downloads a prebuilt i386 .deb binary from Google Code Archive (storage.googleapis.com), which is a Google-operated static archive of the old Google Code hosting service. The host itself is legitimate infrastructure, not a personal or rogue server. However, the artifact is a precompiled binary (not source-built), verified only by an MD5 checksum (cryptographically weak, collision-prone), and the package is old (0.14, pkgrel=5) with no stronger integrity guarantee (no sha256sums, no GPG signature). The binary is then extracted and installed directly into the system. This constitutes a real supply-chain concern: a prebuilt executable from an archived, unmaintained source with only MD5 verification. The Google Archive host reduces but does not eliminate the risk (Google does not re-sign or audit these artifacts). The medium rating is appropriate — not clearly malicious, but a genuine concern due to prebuilt binary + weak checksum + unmaintained archive.
