Cybersecurity Forensics Analysis Using Domain Intelligence Sources

Forensic science has crossed over to the digital world in what is now called “digital or cybersecurity forensics.” And just like their physical crime scene counterparts, cybersecurity forensics experts need to hold on to whatever evidence they have and use it to get one step closer to catching the perpetrator.

Evidence comes in many different forms, but cybercriminals often use domain names and Domain Name System (DNS) infrastructure since those assets are practically what makes the Internet work.

When creating botnets for a distributed denial-of-service (DDoS) attack, for example, threat actors need to infect hundreds or thousands of devices. Each of these devices has an IP address, and the requests they send to the target’s server may sometimes contain the command-and-control (C&C) server domain. Even with their most effective entry point – phishing emails – the bad guys need to use domain names and subdomains.

How to Contact the Owner of a Domain with WHOIS and Website Contacts Products

How to Contact the Owner of a Domain with WHOIS and Website Contacts Products

The Internet is one giant marketplace. If you are looking for a software-as-a-service (SaaS) option that you can use for your department, a simple Google search will give you dozens of them. Meanwhile, if you need someone to promote your business, the Internet can suggest several influencers depending on your niche. Once you find a company or person that matches your requirements, all of you have to do next is to contact the domain owner or website representative(s).

Contacting them may be easy since chatbots or contact forms are always available. But how can you connect with the owners of hundreds or thousands of domains without going through a chatbot or waiting for someone to answer the customer service line in each and every case? To help you, we explored four different ways to contact the owner of a domain.

WHOIS Lookups & Enterprise Cybersecurity Policies: A Secure Way to Search for Domain Names

WHOIS Lookups & Enterprise Cybersecurity Policies: A Secure Way to Search for Domain Names

These days, it’s unwise to assume that all websites are safe to access. For this reason, security teams typically advise employees against clicking on any links embedded in an email, especially from an unknown sender. This recommendation may even extend to suspicious search results that appear in search engines.

What’s more, for most companies, visiting websites that are not related to an employee’s work is a violation of established cybersecurity policies and procedures. Most cybersecurity policies include:

  • Standard steps for accessing work data and applications remotely
  • Rules for encrypting emails
  • Instructions on creating and managing passwords
  • Rules on using social media
  • Guidelines for accessing nonwork-related websites

While this last policy may sound extreme to some, it has become common practice, especially among companies that want to beef up their cybersecurity posture. Their stance is ‘Prevention is better than cure’. And keeping employees from visiting potentially dangerous websites is always safer and more cost-effective than dealing with a ransomware attack or data breach.

Given this policy, though, how can one search for domain names that might help the business gain more customers? In parallel, how can security operation centers (SOCs) investigate suspicious online activities with domain names possibly involved in an attempt or attack? Thankfully, tools such as WHOIS Lookup enable SOCs and businesses in general to do extensive research without violating the cybersecurity policies mentioned above.

Find Out More About an IP Address via WHOIS Lookup and WHOIS API

Find Out More About an IP Address via WHOIS Lookup and WHOIS API

IP addresses are unique identifiers for devices hooked to the internet. These addresses, which are represented by numerical values, allow computers to communicate over the Transmission Control Protocol via IP (TCP/IP). The protocol routes users looking for Internet-connected hosts or websites to the right destinations using IP addresses as a reference. 

However, notably because of inherent design flaws, attackers can spoof IP addresses with the intention of, for example, misdirecting users to dangerous sites. For this reason, among others, it is critical to routinely scan IP addresses passing your network filters to ensure their integrity and identify any potential links to malicious campaigns or networks. 

As part of this process, it is possible to do an IP lookup via WHOIS Lookup and WHOIS API to extract the ownership details of a given address for further inspection. What’s more, both products permit gathering all sorts of relevant details such as if an IP address hosts a domain and which regional Internet registry (RIR) manages the resource.

How to Conduct a Website Domain Search for Cybersecurity Purposes

WHOIS lookups are a viable way for cybersecurity professionals to analyze domains’ integrity. Though they may seem less exciting than, say, deploying some nifty pen-testing tools, WHOIS lookups remain useful as a first step in catching threat actors. 

In fact, identifiers in WHOIS records can clue investigators in on a domain’s past usage and allow them to pinpoint indicators of compromise (IoCs) residing within their networks. With WHOIS data, they can also identify domain associations and effectively map attacks that happened or could happen on their infrastructure. Read on to learn more about why conducting website domain searches is critical to your digital operations, and how WHOIS API and WHOIS Lookup can facilitate it.

What You Can Find Out from a WHOIS IP Search

What You Can Find Out from a WHOIS IP Search

Did you know that an IP address can be a good starting point for a cybercrime investigation or even just a routine check of suspicious activities? For instance, when you go to malware data feeds, or any threat intelligence site, one of the usual indicators of compromise (IoCs) you’ll see are known malicious IP addresses.

However, like any threat data, an IP address becomes utterly useless when it doesn’t provide any meaningful details. What then? Tools such as WHOIS Lookup might help to dig deeper. 

So, what exactly is WHOIS Lookup, and what information can it provide about an IP address?
