Kaiser lookalike domains
Greyphish has recorded 81 domains that resemble Kaiser since February 2026, 10 of them in the last 90 days. All of them are combosquats: Kaiser spelled correctly with a word added. No single ending dominates: they are spread over 21, led by .com and .de. The pace has picked up, with 8 in the last 30 days against 2 in the 30 before. 5 certificates for unregistered .com.ph, .ph, .net.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 27 with a registrar in WHOIS (33% 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.

|---|---|---|---|
| GoDaddy | 9 | 33.3% | Retail |
| MarkMonitor | 3 | 11.1% | Brand protection |
