Typosquatting Is No Longer a User Problem — It's a Supply-Chain Vulnerability

Colleagues, note: in cybersecurity typosquatting has shifted from a user-facing nuisance to a supply-chain attack — malicious lookalike domains are being injected into third-party scripts.

• What happened: LLMs generate thousands of similar domains; attackers embed them into legitimate libraries and extensions (e.g. Trust Wallet — $8.5M lost).
• Blind spot in defenses: WAF, EDR, CSP and server logs can’t observe script behavior after execution in the browser.
• Practical steps: prioritize runtime monitoring for payment and login pages, audit newly registered CDN domains, implement SRI and tighten CSP.

Why it matters: without observing script execution, data exfiltration and tampering will remain undetected.

How ready are your payment pages?
