Software supply chain attacks keep climbing and attackers are getting better at slipping malicious code into trusted software. Code signing certificates are meant to stop exactly that, they help developers prove the origin of their applications and assure users that the code hasn’t been altered along the way. But owning a certificate is only half the story. Many teams unintentionally weaken their security by mismanaging private keys, reusing passwords, storing certificates in unsafe locations, or treating code signing as a “set-and-forget” task. These mistakes open the door to injection attacks, unauthorized builds, and tampered releases, the very threats code signing is designed to prevent. In this article, we’ll break down the most common mistakes developers make with code signing certificates and why they matter. More importantly, you’ll learn practical ways to avoid them so you can ship trusted software and maintain the integrity of your build pipeline. What Code Signing Certificates Do? Code signing certificates assure that the software, scripts, containers, or executables are of a reputable origin. It helps users identify whether the publisher of the software, app, or code is authentic. This is done through a pair of security keys. One is stored by the publisher securely, while […]
