MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary (Alpemix) from alpemix.com, which is the official vendor website for this remote desktop product. The main binary has an md5sum check (310efc91c7ac9cfc8172de8fb3f6ec67), which provides some integrity verification. However, two sources (the .desktop file and icons.zip) have SKIP checksums — the icons.zip is particularly notable since it's a local/bundled file with no URL shown, meaning its origin and integrity are completely unverifiable. The core concern is the prebuilt binary from a non-major vendor: alpemix.com appears to be the legitimate upstream, but it's a small/obscure vendor and the binary is executed directly. This is a classic -bin package pattern for a proprietary remote desktop tool. The medium rating is appropriate: it's a prebuilt binary from a small vendor (not a major forge), with partial checksum coverage, and remote desktop software has elevated privilege/network access implications. Not clearly malicious, but a genuine supply-chain concern due to the unverifiable binary nature and SKIP checksums on additional sources.
