Supply Chain Security for Developers: Protecting Your CI/CD Pipeline in 2026 The SolarWinds attack was the wake-up call. Log4Shell was the alarm. The XZ Utils backdoor was the fire drill. In 2026, supply chain attacks are the #1 vector for compromising software organizations — and most CI/CD pipelines are still wide open. This isn't a theoretical risk. If an attacker compromises a single dependency in your build pipeline, they own every deployment downstream. Here's how to lock it down.

Let's secure them one by one. 1. Lock Your Dependencies The first line of defense: know exactly what you're running. Pin Everything, Hash Everything # pyproject.toml — use exact versi
