MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb package from home-store-packages.uniontech.com, which is the UOS (UnionTech OS / Deepin) app store package repository. This is not the official rishiqing.com release channel, but rather a third-party Linux distribution's app store mirror. The package contains an Electron-based binary that gets extracted and executed directly. While uniontech.com is a legitimate Chinese Linux vendor (makers of Deepin/UOS), this is still a prebuilt binary from a distribution app store rather than the upstream vendor's own release infrastructure, creating a supply-chain dependency on that store's integrity. The sha512sum provides some integrity protection against transit tampering, but does not protect against the upstream host serving a malicious package. The binary is executed directly from /opt without any build-from-source step. This fits the medium classification: a real supply-chain concern (executed binary from a non-official/non-upstream host) but 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, …).
