Udemy lookalike domains
Greyphish has recorded 105 domains that resemble Udemy since February 2026, 22 of them in the last 90 days. Most of them (77%) are typosquats, a keystroke or two away from the real name. .com carries 97% of them, out of 4 endings in all. 16 certificates for unregistered .ph, .com.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 90 with a registrar in WHOIS (86% 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.
| Registrar | Lookalikes | Share | Type |
|---|---|---|---|
| SafeNames | 16 | 17.8% | Brand protection |
| GoDaddy | 12 | 13.3% | Retail |
| PDR | 7 | 7.8% | Retail |
| Dynadot | 6 | 6.7% | Retail |
| Namecheap | 6 | 6.7% | Retail |
| Spaceship | 5 | 5.6% | Retail |
| Above.com | 3 | 3.3% | Retail |
