In the course of protecting our client portfolios, we come across hostile domain names that pose a risk to the community at large.

Domainsure makes these feeds available to other security vendors, DNS resolvers, and service providers as a way to collaborate and share data about harmful and hostile domain names.

The following Realtime Blocklists (RBLs) are available:
(as of Feb 23, 2024)

Domainsure Crypto Defender RBL

Live phishes, clones, malware sites targeting known crypto and Bitcoin exchanges, wallets, DeFi platforms, token projects, DAOs and blockchains.

Query:

Domainsure Verified Phishing RBL
