Why Trusted Publishing May Not Be Reliable for Software Distribution

The blog entry cautions readers against assuming the safety of Trusted Publishing mechanisms. It explains how the model is intended to verify software provenance through signatures. The author points out that compromised keys or misconfigured trust stores can undermine that assurance. Real‑world examples show attackers exploiting the trust chain to deliver malicious binaries. The post highlights the difficulty of maintaining an up‑to‑date list of trusted publishers. It recommends additional verification steps beyond the built‑in trust model. The author suggests using reproducible builds and independent audits where possible. Readers are urged to treat Trusted Publishing as one layer of defense, not a guarantee.
