While supply chain threats have been quietly compounding over the past decade, the last 12–18 months have triggered a drastic shift in the scale and velocity of these attacks. Rather than just hunting for bugs in finished software, attackers are targeting the everyday tools and code developers rely on.

We’ve observed attackers spending years pretending to be helpful contributors just to hide backdoors in core software, as seen in the XZ Utils vulnerability (CVE-2024-3094). We’ve seen attackers hijack accounts to drop malware into popular libraries, like in the Axios supply chain attack. And we’ve seen them misuse setup scripts to automatically steal credentials using the Shai-Hulud npm worm.
