LOW

Why flagged The source is downloaded from download.brother.com, which is Brother's official download infrastructure (same domain used by all Brother Linux driver packages in the AUR). The file is a prebuilt i386 .deb containing a CUPS wrapper driver, which is a binary, but it comes from the vendor's own servers rather than a personal or unofficial host. The PKGBUILD is sloppy (uses md5sums instead of sha256sums, no integrity check beyond a weak hash, installs a 32-bit binary on potentially 64-bit systems without lib32 deps, missing extract step before tar -xf data.tar.gz), but these are quality issues rather than supply-chain threats. The cheaper model's MEDIUM rating is a false positive — official vendor binary drivers from the vendor's own domain are a standard AUR pattern and not a supply-chain concern beyond the inherent trust placed in the vendor.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 85%): The source is downloaded from download.brother.com, which is Brother's official download infrastructure (same domain used by all Brother Linux driver packages in the AUR). The file is a prebuilt i386 .deb containing a CUPS wrapper driver, which is a binary, but it comes from the vendor's own servers rather than a personal or unofficial host.
