HashiCorp lookalike domains
Greyphish has recorded 206 domains that resemble HashiCorp since February 2026, 47 of them in the last 90 days. Nearly all of them (97%) are combosquats: HashiCorp's name or one of its product names spelled correctly with a word added, most often “app”, “true”, “secure”. No single ending dominates: they are spread over 48, led by .com and .xyz. The pace has picked up, with 19 in the last 30 days against 12 in the 30 before. 9 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 90 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.
