Our Commentary ​

This Axios supply chain attack is genuinely alarming. Axios is practically ubiquitous in the JavaScript ecosystem, and the idea that a malicious dependency could sneak in and affect so many projects is a stark reminder of the fragility of our software supply chain. This incident underscores the critical need for robust security practices like dependency pinning, careful review of post-install scripts, and proactive monitoring. It's a wake-up call for the entire community. As a solution from our side we can totally recommend configuring a cooldown strategy in your package manager.
