Why flagged

This PKGBUILD downloads a prebuilt binary .deb from an AWS S3 bucket (prod-thinkboxai-setups.s3-accelerate.amazonaws.com) and installs its contents directly into the package root. The concerns are real: (1) sha256sums='SKIP' means there is no integrity verification whatsoever — any tampering or substitution of the S3 object would go undetected; (2) the source is a prebuilt binary from a personal/vendor S3 bucket rather than a distro-standard or well-known official release host, so the supply chain is entirely dependent on that bucket's security; (3) the package extracts and installs the full .deb contents including whatever executables and libraries are inside, without any inspection or filtering. The license is listed as 'unknown', which is a minor additional concern. This is a genuine medium-severity supply-chain risk: not clearly malicious, but an executed binary from an unofficial 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, …).
