Why flagged

The PKGBUILD downloads a prebuilt binary ZIP from nion.com (the official vendor website for Nion Co.'s NionSwift software), extracts it, and installs a native executable binary directly to /usr/local/NionSwift/NionSwift which is then symlinked into /usr/bin. The source host is the official vendor domain, not a personal or unofficial host, which reduces but does not eliminate risk. However, md5sums=('SKIP') means there is no integrity verification of the downloaded binary — if the upstream host were compromised or the file replaced, users would silently receive a malicious binary. The installed artifact is an executed binary (not pure data), so the lack of checksum verification is a genuine supply-chain concern. This is a textbook medium: prebuilt binary from a vendor host with no checksum verification.

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, …).
