Why flagged

The PKGBUILD downloads a prebuilt binary .deb from ca.ica.cz (I.CA, a Czech certificate authority) and installs a PKCS#11 shared library (libICASecureStorePkcs11.so) directly into /usr/lib/pkcs11/. This is a real supply-chain concern: a prebuilt, closed-source native shared library from a vendor's own distribution server is installed and will be loaded into sensitive cryptographic contexts (smart-card operations via p11-kit). The host ca.ica.cz appears to be the legitimate upstream vendor (I.CA is a well-known Czech CA), and the sha256sum is pinned, which mitigates some risk. However, there is no GPG signature verification, the library is proprietary/unauditable, and a compromised or malicious .so in the PKCS#11 slot could intercept private key operations. This is a textbook medium: not clearly malicious, but an executed binary from a non-standard (even if plausibly legitimate) vendor host with no cryptographic signature check beyond a hash.

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, …).
