MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from download.wondershare.com (the official Wondershare vendor download domain) and installs it directly into the package tree by extracting data.tar.xz. Wondershare is a legitimate commercial software vendor and this is their official download host, so this is not an unofficial or personal host. However, the package installs a prebuilt proprietary binary blob without any signature verification beyond a single MD5 checksum (which is cryptographically weak and trivially forgeable). The URL is also not pinned to a versioned path — 'ubuntu-mockitt_full8041.zip' is an opaque filename that could be silently replaced server-side. There is no GPG signature or SHA256/SHA512 hash. The installed binary runs with user privileges as a desktop application. This is a real supply-chain concern (weak integrity check on an executed binary from a vendor host), justifying MEDIUM, though it is 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, …).
