Basecamp lookalike domains
Greyphish has recorded 90 domains that resemble Basecamp since February 2026, 20 of them in the last 90 days. They split between combosquats (54%) and typosquats (44%). .com carries 73% of them, out of 22 endings in all. The pace has picked up, with 12 in the last 30 days against 5 in the 30 before. 3 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 60 with a registrar in WHOIS (67% 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 | 15 | 25.0% | Retail |
| Cloudflare | 8 | 13.3% | Retail |
| Squarespace | 5 | 8.3% | Retail |
| Namecheap | 4 | 6.7% | Retail |

Recent examples
The 10 most recent, written with [.] so they cannot be clicked. The brand's own domains and registrations held by brand-protection registrars are left out. A lookalike resembles Basecamp; it is not necessarily malicious, and none of these is a claim about who registered it or why.

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