The internet relies heavily on DNS, and criminals are not exempt. DNSDB exploits the fact that cyber criminals share and reuse resources.

DNSDB is a Passive DNS historical database that provides a unique, fact-based, multifaceted view of the configuration of the global Internet infrastructure. DNSDB leverages the richness of Farsight’s Security Information Exchange (SIE) data-sharing platform and is engineered and operated by leading DNS experts. And with Flexible Search, introduced in DNSDB 2.0, analysts can apply regular expressions, making this resource even more versatile and powerful.
