Identify similar phishing domains that could be leveraged by attackers against your organization. Investigate the potential issues users may face when attempting to type your domain name accurately. Look for fraudulent domains that adversaries might exploit for malicious purposes, as this can help in identifying typosquatters, phishing schemes, scams, and instances of brand impersonation. This information serves as a valuable resource for enhanced targeted threat intelligence. The process of DNS fuzzing automates the detection of potentially harmful domains aimed at your organization by creating a vast array of variations from a specified domain name and checking if any of these variations are active. Furthermore, it can produce fuzzy hashes of web pages to identify ongoing phishing attempts, instances of brand impersonation, and additional threats, thereby providing a more comprehensive security measure. By utilizing this tool, organizations can significantly bolster their defenses against evolving cyber threats.
