Why flagged

The PKGBUILD downloads a prebuilt binary (DivX265) directly from download.divx.com — the official DivX/Rovi/Xperi download infrastructure — and installs it as an executable. While download.divx.com is the legitimate vendor host for DivX products, the binary is not accompanied by a GPG signature; only an MD5 checksum is used for integrity verification. MD5 is cryptographically broken and provides weak protection against targeted substitution. The binary is a closed-source, proprietary HEVC encoder distributed as a prebuilt executable, which is a real supply-chain concern: if the host were compromised or the file swapped, the weak checksum would not reliably detect it. The package is also quite old (v1.5.8, pkgrel=1) and the URL scheme suggests a direct binary download rather than a versioned release artifact. This is a genuine medium-risk pattern — executed proprietary binary with only MD5 integrity — but not clearly malicious, as the host is the official vendor domain.

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, …).
