MEDIUM

Why flagged The PKGBUILD downloads prebuilt binary .deb packages from nscope.org (the official vendor site for the nScope USB oscilloscope product), extracts them, and installs the binaries directly. While nscope.org appears to be the legitimate upstream vendor host, this is still a prebuilt binary from a third-party/vendor host with only MD5 checksums (a weak, collision-vulnerable hash) for integrity verification. There is no GPG signature verification. The binary is executed code installed directly onto the system. This fits the classic medium supply-chain risk pattern: not clearly malicious, but an unofficial/vendor binary host with weak integrity checks means a compromised host or MITM could deliver malicious binaries. The cheaper model's assessment is correct here — this is a genuine medium concern, not a false positive.

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, …).
