MEDIUM

Why flagged The package downloads a prebuilt binary .deb from home-store-packages.uniontech.com, which is the UOS (UnionTech OS / Deepin) official app store package repository — not a random personal host, but also not the upstream vendor (codemao.cn) directly. The binary is an Electron/Chromium-based application executed as root-installed code. There is a sha512sum check, which mitigates tampering risk somewhat, but the source is a third-party app store mirror rather than the upstream developer's own distribution channel. The extracted binary runs with broad filesystem permissions (chmod -R 755) and is an Electron app launched with --no-sandbox. This is a legitimate medium-risk pattern: prebuilt closed binary from a non-upstream host with a checksum but no GPG signature, representing a real supply-chain concern if the app store host is compromised. Not clearly malicious, but not clean either.

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, …).
