MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from labs.picotech.com, which is PicoTech's own Linux software repository (the official vendor lab/beta mirror), not a random personal host. However, it is still a prebuilt binary blob with only an MD5 checksum (cryptographically weak, collision-prone) and no GPG signature verification. The binary is extracted and installed directly into the system. This constitutes a real supply-chain concern: if the host or the file were compromised, arbitrary native code would be installed with no strong integrity guarantee. The host is vendor-associated but not the primary official domain, and MD5 is insufficient for binary integrity. This is a genuine medium-severity concern — not a false positive — but also 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, …).
