Bluesky lookalike domains
Greyphish has recorded 126 domains that resemble Bluesky since February 2026, 35 of them in the last 90 days. All of them are combosquats: Bluesky spelled correctly with a word added, most often “service”, “web”, “account”. No single ending dominates: they are spread over 50, led by .com and .net. The pace has picked up, with 23 in the last 30 days against 6 in the 30 before. The busiest week began 5 October 2026, with 18 new ones. 4 certificates for unregistered .com.ph, .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.
