MEDIUM

Why flagged The package downloads a prebuilt binary .deb (an Electron/Chromium-based application) from home-store-packages.uniontech.com, which is the Deepin/UOS app store mirror operated by UnionTech (统信软件), the company behind UOS/Deepin Linux. This is not the software vendor's (Pixso/Bosyun) own distribution channel, but rather a third-party app store repository. The binary is a closed-source, prebuilt Electron application that gets executed directly on the user's system. While uniontech.com is a legitimate Chinese Linux distribution company and their app store is a real platform (not a random personal host), it is still not the upstream vendor's official release channel, creating a supply-chain risk: if the package in the UnionTech store were compromised or substituted, users would execute malicious code. The sha512sum provides some integrity protection against in-transit tampering but does not protect against the upstream store serving a malicious binary. This is a genuine medium-severity concern: a prebuilt, closed-source, executed binary from a non-upstream distribution host.
