Supply Chain Attacks Explained

Instead of attacking you directly, attackers compromise a trusted vendor or software update you already use. When you install the compromised update, the malware comes along. It's especially dangerous because you're trusting software you've been using safely for years.

You can't fully prevent them (you can't audit every line of code in every tool you use), but you can limit the damage: keep software updated (paradoxically), use defense-in-depth, monitor for unusual behavior, minimize the number of tools/extensions you use, and prefer open-source software where code is publicly auditable.

Remote workers often use more third-party tools than office workers (VPNs, collaboration apps, cloud services). Each tool is a potential supply chain target. Use reputable, audited tools, keep them updated, and prefer providers with transparency reports and open-source code.
