Can I take down a typosquat domain?

Sometimes. Legitimate paths include a UDRP (Uniform Domain-Name Dispute-Resolution Policy) complaint with the registrar or ICANN — cheap and fast against clear infringement — and, for active phishing, a takedown request routed through the hosting provider or CDN. Registrars vary in cooperation. The realistic goal is not zero lookalikes; it is faster detection than the attacker’s monetization window.
