Why flagged

The PKGBUILD downloads a prebuilt binary .deb from bytecoin.org (the official Bytecoin project website, not a personal/random host), extracts it, and installs the binaries directly. While bytecoin.org is the upstream vendor's own domain, installing prebuilt binaries from any external host — even an official one — carries supply-chain risk: there is no source build, no reproducibility, and the integrity check is only MD5 (weak, collision-prone). The concern is real but not clearly malicious: this is a pattern common in AUR packages that wrap upstream binary releases. The medium rating is appropriate because executed binaries from an external host (even the official one) bypass source-level auditing, and MD5 provides insufficient integrity assurance.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
