Why flagged

The PKGBUILD downloads a prebuilt binary .deb from toofifi.cn, which is not the project's primary domain (transcreen.pro). This is a real supply-chain concern: a precompiled binary is extracted and installed directly into the system (opt/ and usr/), with no source build. The sha256sum provides integrity against tampering in transit but does not protect against the host serving a malicious binary from the start. The domain toofifi.cn appears to be a CDN or distribution host used by the vendor, but it is not the canonical project URL, making it impossible to verify the chain of custody without further investigation. This pattern — executed binary from a non-primary host — is the textbook medium-risk case.

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, …).
