MEDIUM

Why flagged The PKGBUILD downloads a prebuilt .deb from packages.ntop.org, which is ntop's official Debian/Ubuntu package repository (ntop is the legitimate vendor of PF_RING). This is not a random personal host — ntop.org is the upstream vendor and packages.ntop.org is their official distribution channel, analogous to how other vendors host their own apt/yum repos. The sha256sums are pinned, providing integrity verification against the specific binary. However, the concern is real in the sense that: (1) a prebuilt binary kernel module source package is being extracted and installed via DKMS, meaning compiled kernel code will be executed in ring 0; (2) the source is a binary .deb rather than source code from the canonical GitHub repo (https://github.com/ntop/PF_RING); (3) packages.ntop.org is an external binary host not under AUR/Arch infrastructure control. The sha256 pinning mitigates substitution attacks but not a compromised upstream release. This is a genuine supply-chain concern (prebuilt binary from vendor's own repo rather than building from source) but not clearly malicious — it is a common pattern for DKMS packages where the vendor distributes source via their package repo. Rating remains MEDIUM: real concern, not an attack.
