Typosquatting Is No Longer a User Problem. It's a Supply Chain Problem

Typosquatting has evolved into a supply chain problem where attackers embed malicious domains in legitimate third-party scripts without requiring user mistakes or server breaches.

• •Real attacks include chalk/debug npm compromise affecting 2 billion downloads, Solana Web3.js private key interception, and browser runtime behavior modification
