How to Build an Attack Profile with WHOIS Database Download as a Starting Point

Fighting cybercrime is a never-ending battle. As threat actors continue to craft different ways to attack and scam their target victims, companies need to build their security arsenals to fight against all kinds of threats. What’s more, an effective way to achieve cyber resilience is by getting to know the enemy and build attack profiles.


That’s possible with the help of a WHOIS database. While the Internet can provide a trove of information about specific individuals and organizations, robust WHOIS information can also offer security researchers and threat hunters value — especially when it comes to identifying threat actors and investigating indicators of compromise (IoCs) for further investigation.


Building an Attack Profile Using WHOIS Database Download


WHOIS Database Download has proven a useful ally to security experts when it comes to bolstering threat hunting. Information obtained from WHOIS records can reveal who is behind an attack, such as the offending domain’s owner, organization, and more. When correlated with data gleaned from other security tools, a WHOIS database can help reveal connected domains, individuals, and other IoCs — allowing security teams to build attack profiles. Here’s how:


1. Look for Domain Connections


WHOIS Database Download is available in MySQL or comma-separated values (CSV) format. Once you have access to the database, you can retrieve more information about a particular domain with its help. You can use any of the following to filter data and spot similarities that can reveal ties to malicious activity:


  • Domain name

  • Contact email address

  • Registrant name

  • Registrant email address

  • Registrant organization

  • Let us say you a ..
