Bitdefender lookalike domains
Greyphish has recorded 146 domains that resemble Bitdefender since February 2026, 74 of them in the last 90 days. Most of them (62%) are typosquats, a keystroke or two away from the real name. .com carries 76% of them, out of 33 endings in all. The pace has picked up, with 71 in the last 30 days against 1 in the 30 before. The busiest week began 21 September 2026, with 37 new ones. 24 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 111 with a registrar in WHOIS (76% 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.

|---|---|---|---|
| Corsearch | 69 | 62.2% | Brand protection |
| EuroDNS | 8 | 7.2% | Retail |
