GitHub lookalike domains
Greyphish has recorded 169 domains that resemble GitHub since February 2026, 21 of them in the last 90 days. Most of them (66%) are typosquats, a keystroke or two away from the real name. .com carries 88% of them, out of 16 endings in all. The pace is steady: 8 in the last 30 days, 7 in the 30 before. 119 certificates for unregistered .ph, .com.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 143 with a registrar in WHOIS (85% 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 | 21 | 14.7% | Retail |
| Cloudflare | 15 | 10.5% | Retail |
| Dynadot | 11 | 7.7% | Retail |
| NameSilo | 11 | 7.7% | Retail |
| Namecheap | 11 | 7.7% | Retail |
| Key-Systems | 7 | 4.9% | Retail |
| Alibaba Cloud | 6 | 4.2% | Retail |

Greyphish is not affiliated with GitHub. Domains listed resemble GitHub 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.
