Coinbase lookalike domains
Greyphish has recorded 511 domains that resemble Coinbase since February 2026, 98 of them in the last 90 days. Most of them (88%) are combosquats: Coinbase spelled correctly with a word added, most often “wallet”, “support”, “help”. .com carries 52% of them, out of 76 endings in all. The pace has picked up, with 43 in the last 30 days against 26 in the 30 before. 955 certificates for unregistered .net.ph, .com.ph, .ph names (registry wildcard) are excluded: the registry answers for any name under those endings, so nobody had to register one to get a certificate for it.

Where they are registered
For the 289 with a registrar in WHOIS (57% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.
