MEDIUM

Why flagged This PKGBUILD downloads and installs a prebuilt binary tarball (BlackWallet.tar.gz) directly from the vendor's own website (blackwallet.com.br). The binary is extracted and installed to /opt and executed via a wrapper script. Key concerns: (1) it is a prebuilt, closed-source binary from a single personal/commercial host with no source build, meaning users must fully trust that host; (2) pkgver=rolling with no versioning means the checksum could become stale or the tarball could be silently replaced; (3) the package is a financial application (Brazilian stock market wallet manager), making supply-chain compromise particularly impactful. However, the sha256sum is present and fixed, the host is the official project URL matching the url= field, and there is no obfuscation or unusual execution pattern. This is a legitimate medium-risk pattern: an executed prebuilt binary from an unofficial/personal host without source, not a clear attack.

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, …).
