Why flagged

The PKGBUILD downloads a prebuilt binary .deb from repository.infonotary.com, which is the official repository of InfoNotary — a Bulgarian qualified trust service provider (QTSP) under eIDAS. This is not a random personal host; it is the vendor's own distribution server. However, the integrity check uses only an MD5 checksum (cryptographically broken, trivially collisable) rather than a SHA256/SHA512 hash or a GPG signature. The package installs executed binaries (Qt5-based GUI applications and smart card middleware) directly from this vendor host without any signature verification. While InfoNotary is a legitimate company, the weak integrity check (MD5 only) combined with a prebuilt binary from a non-Arch-official host constitutes a real, if modest, supply-chain risk: a MITM or server compromise could substitute the binary and the MD5 check would not reliably catch it. This fits the medium category: executed binary from an unofficial (non-distro) host with insufficient integrity verification, but not clearly malicious.

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, …).
