Kayak lookalike domains
Greyphish has recorded 128 domains that resemble Kayak since February 2026, 14 of them in the last 90 days. Most of them (75%) are typosquats, a keystroke or two away from the real name. .com carries 85% of them, out of 16 endings in all. The pace is steady: 4 in the last 30 days, 5 in the 30 before. 6 certificates for unregistered .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 105 with a registrar in WHOIS (82% 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 |
|---|---|---|---|
| GoDaddy | 17 | 16.2% | Retail |
| Dynadot | 9 | 8.6% | Retail |
| Media Elite Holdings | 9 | 8.6% | Retail |
| Above.com | 7 | 6.7% | Retail |
| NameBright | 6 | 5.7% | Retail |

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 Kayak; it is not necessarily malicious, and none of these is a claim about who registered it or why.

Greyphish is not affiliated with Kayak. Domains listed resemble Kayak by spelling; registration alone says nothing about intent. Counts cover domains first seen in public Certificate Transparency logs and ICANN zone files; domains that Greyphish customers watch are excluded.
