Greyphish has recorded 90 domains that resemble HubSpot since February 2026, 29 of them in the last 90 days. They split between typosquats (51%) and combosquats (43%). .com carries 74% of them, out of 10 endings in all. The pace has picked up, with 20 in the last 30 days against 5 in the 30 before. The busiest week began 28 September 2026, with 11 new ones. 13 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 77 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.
