MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from the official project domain (podpisuj.sk), extracts it, and installs the contents directly. This is a legitimate pattern for proprietary software that does not distribute source code, and the sha256sum is pinned. The risk is real but typical for binary repacks: if the upstream host is compromised or the maintainer updates the checksum to a malicious build, arbitrary code executes on the user's system. The host is the vendor's own domain (not a personal/random host), which slightly reduces but does not eliminate supply-chain concern. This is a standard medium-severity binary repack — not a false positive, but not an active attack either.

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, …).
