Why flagged

A prebuilt binary (avr_sim) is downloaded from vin.ovh, which is the maintainer's own personal domain (matching the maintainer email jk@vin.ovh), not the original upstream (avr-asm-tutorial.net, which appears defunct per the web.archive.org URL). The binary is installed directly to /usr/bin. SHA256 checksums are present and provide integrity against post-publication tampering, but since the maintainer controls both the PKGBUILD and the hosting server, this is a genuine supply-chain concern: the maintainer could serve a malicious binary and update the checksum simultaneously. This is a textbook medium-risk pattern — an executed binary from an unofficial/personal host rather than the original vendor.

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, …).
