They split between typosquats (58%) and combosquats (42%). .com carries 73% of them, out of 14 endings in all. 2 certificates for unregistered .ph names (registry wildcard) are excluded: the registry answers for any name under that ending, so nobody had to register one to get a certificate for it.

Where they are registered

For the 45 with a registrar in WHOIS (73% 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.

Recent examples

The 10 most recent, written with [.] so they cannot be clicked. The brand's own domains and registrations held by brand-protection registrars are left out. A lookalike resembles ProtonVPN; it is not necessarily malicious, and none of these is a claim about who registered it or why.
