Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Fastify hit version 5.0 in September 2024 with a slimmer core, a plugin model that encourages correctness, and a security track record that genuinely distinguishes it from the Express crowd. Here is what I have learned auditing Fastify apps this year.
Prototype pollution lets attackers modify the behavior of all JavaScript objects by injecting properties into Object.prototype. This guide covers exploitation techniques, real-world impact, and layered defenses.
Node.js finally has an experimental permission model. It is a significant step toward containing supply chain attacks, but it has important limitations.
Express remains the default Node.js framework at most shops, and its middleware ecosystem is a thirteen-year accumulation of packages, some abandoned, some indispensable. This is a pragmatic audit of what belongs in a 2023 Express stack.
Electron's ContextBridge is the secure boundary between web content and Node.js APIs. This guide covers how to use it correctly, common mistakes that create RCE vulnerabilities, and security best practices for Electron applications.
A fundamental flaw in npm's package handling allowed published package metadata to differ from actual package contents, undermining trust in the entire ecosystem.
Lockfile injection is a subtle supply chain attack where malicious changes to package-lock.json redirect dependency resolution to attacker-controlled packages. Here is how it works and how to detect it.
Electron apps ship a full Chromium browser and Node.js runtime to the desktop. That means every web supply chain risk becomes a desktop attack surface — with elevated privileges.
