Why flagged

This PKGBUILD downloads and installs a prebuilt binary (ishell_pro, a Flutter-based SSH client) from down.ishell.cc, which is the vendor's own download subdomain matching the product's official URL (www.ishell.cc). The host appears to be the legitimate vendor distribution point rather than a random personal host, which reduces but does not eliminate supply-chain risk — there is no code-signing or GPG verification, only a sha256sum. The binary is an SSH client that handles credentials and connections, making any compromise particularly impactful. The sha256sum has only 63 hex characters (should be 64), which is a checksum integrity issue. The PKGBUILD also has shell syntax errors (missing spaces in `if [!` and `if [-f`), making it likely broken. Overall: a prebuilt closed-source binary from a vendor subdomain with a malformed checksum and no signature verification is a genuine medium supply-chain concern, not a false positive.

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, …).
