MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary tarball from bearware.dk (the official TeamTalk project website) and installs it directly into /opt. The host is the legitimate upstream vendor site for TeamTalk, not a personal or unofficial mirror. However, the concern is real: prebuilt binaries from any external host (even the official one) bypass source compilation and reproducibility, meaning a compromised upstream host or a MITM could deliver malicious executables. The sha256sums provide some protection against tampering in transit, but do not protect against the upstream host itself being compromised and serving a new binary with updated checksums. The binary is also built for Ubuntu 22 and installed on Arch, which is a compatibility concern but not a security one. Overall this is a legitimate but supply-chain-risky pattern (prebuilt binary from upstream vendor), which fits the medium classification — not a false positive, but also not clearly malicious.

Triggered rules
