Why flagged

The PKGBUILD downloads and installs a prebuilt binary .deb package (a shared library libbit4xpki.so and associated files) from repository.infonotary.com. InfoNotary is a Bulgarian qualified trust service provider (CA) that distributes Bit4ID smart card middleware for their PKI infrastructure, so this is a plausible legitimate vendor mirror rather than a random personal host. However, it is still a third-party binary distribution host (not the upstream bit4id.com itself), the license is listed as 'unknown', and the package installs executed native code (smart card middleware/library) directly from this host. An md5sum is provided but MD5 is cryptographically weak. The supply-chain concern is real: if repository.infonotary.com were compromised, arbitrary native code would be installed into /usr/lib. This fits the medium category — a prebuilt binary from an unofficial/third-party host with weak 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, …).
