Why flagged

The PKGBUILD downloads a prebuilt binary .deb package (a Smart Card middleware driver containing shared libraries) from repository.infonotary.com, which is not the vendor's primary domain (bit4id.com). InfoNotary appears to be a Bulgarian certificate authority that redistributes Bit4ID software, so this is plausibly a legitimate redistribution mirror rather than a personal/rogue host. However, the source is still a third-party host for executed native code (shared libraries installed into /usr/lib), and there is no cryptographic verification beyond an MD5 checksum (which is weak). The package extracts and installs the .deb contents directly without any signature verification. This constitutes a real supply-chain concern: silent substitution at the redistribution host would result in arbitrary native code execution. The risk is genuine but not clearly malicious, consistent with a MEDIUM rating.

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, …).
