Why flagged

The PKGBUILD downloads a prebuilt binary installer (.bin) from files.certum.eu, which is the official Certum/Asseco vendor file distribution host (Certum is a Polish CA/PKI vendor). The binary is executed via `sh ... --noexec --keep` to extract its payload, and the extracted contents are then installed. This is a legitimate vendor pattern for self-extracting installers, and files.certum.eu is the official Certum software distribution domain matching the package's stated purpose. However, the integrity check uses only MD5 (weak, collision-prone) rather than SHA-256 or a cryptographic signature, and the source is a prebuilt binary blob from a vendor host rather than source code — meaning any compromise or substitution at the host level would result in arbitrary code execution on the user's system. This is a genuine medium-severity supply-chain concern (executed binary from a non-PyPI/non-GitHub official host with only MD5 verification), not a false positive, but also not evidence of active malice.

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, …).
