    Article summary

    Certificates are used in the authentication process to establish secure connections between devices, such as web browsers and servers, or to digitally sign files or emails.

    In the context of threat intelligence, certificate information is useful in a number of ways:

    1. Identifying malicious websites and phishing attacks. Many attackers use fake or stolen certificates to make their websites appear legitimate, but analyzing certificate information helps to detect these fraudulent sites.

    2. Tracking the activities of threat actors. By analyzing certificate information, security analysts can identify patterns and connections between different attacks, as well as the infrastructure and resources used by specific threat actors.

    3. Verifying the authenticity of digital communications. By using certificate information to confirm the identity of a sender, or the authenticity of a file, security teams can reduce the risk of falling victim to phishing, malware, or other attacks.
