Comcast lookalike domains
Greyphish has recorded 214 domains that resemble Comcast since February 2026, 37 of them in the last 90 days. They split between typosquats (51%) and combosquats (43%). .com carries 76% of them, out of 22 endings in all. The pace has picked up, with 17 in the last 30 days against 8 in the 30 before. The busiest week began 6 July 2026, with 22 new ones. 21 certificates for unregistered .ph, .com.ph, .org.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 136 with a registrar in WHOIS (64% 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.
