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

**Executive summary:** The article warns that modern typosquatting and supply-chain subversion now embed lookalike domains and malicious behavior inside trusted third-party scripts and packages, citing multiple incidents (a trojanized Trust Wallet Chrome extension attributed to the Shai-Hulud npm worm, widespread malicious updates to popular npm libraries, and a compromised @solana/web3.js release) that caused substantial crypto theft and demonstrated that traditional controls (firewalls, WAFs, CSP, server logs) lack visibility into browser-runtime execution; it recommends prioritizing payment/authentication pages, auditing recently registered CDN domains, and deploying runtime behavioral monitoring and baselines to detect unexpected data exfiltration and dynamic domain resolution.
