Delta lookalike domains
Greyphish has recorded 577 domains that resemble Delta since February 2026, 170 of them in the last 90 days. Most of them (81%) are combosquats: Delta spelled correctly with a word added, most often “web”, “service”, “app”. No single ending dominates: they are spread over 106, led by .com and .xyz. The pace has picked up, with 108 in the last 30 days against 27 in the 30 before. The busiest week began 5 October 2026, with 52 new ones. 40 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 252 with a registrar in WHOIS (44% 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 | 48 | 19.1% | Retail |
| NameBright | 12 | 4.8% | 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 Delta; it is not necessarily malicious, and none of these is a claim about who registered it or why.
