Case Study: Rexxfield accelerates cybercrime investigations with WhoisXML API domain intelligence

Rexxfield cuts investigation time by 50% with WhoisXML API

Rexxfield, a cyber investigations firm, faced the challenge of efficiently uncovering and attributing complex malicious infrastructure used in online fraud and digital threats. Beginning with limited indicators like a single domain, their investigators needed to reliably map entire domain ecosystems and link related campaigns. To accelerate this process, they partnered with vendor WhoisXML API and utilized products including the DNS Database Download, Reverse WHOIS API, and WHOIS API.

The solution implemented by WhoisXML API provided Rexxfield with deep domain intelligence, allowing them to pivot from a single indicator to uncover hidden relationships and map interconnected fraud networks. This integration acted as a force multiplier, resulting in a 50% reduction in investigation time. The partnership delivered stronger attribution for legal action and more effective disruption of cybercriminal operations.
