DNSFISH

DNSFISH is an open-source phishing tool designed to automate the creation and deployment of fake DNS servers. Its primary purpose is to intercept and redirect user traffic to malicious websites, a technique often employed in phishing attacks. The tool works by setting up a rogue DNS server that responds to specific domain queries with the IP address of a controlled server. When a user attempts to access a legitimate website, their DNS request is intercepted by DNSFISH, and they are instead directed to a fake version of the site hosted by the attacker.

This redirection can be used to harvest credentials, personal information, or distribute malware. DNSFISH offers features such as customizable domain blacklisting and whitelisting, allowing attackers to target specific services or avoid certain domains. It can also be configured to mimic legitimate DNS responses, making it more difficult for users to detect the malicious activity. The tool is typically used by security researchers for penetration testing and by malicious actors for cybercrime. Understanding DNSFISH's functionality is important for cybersecurity professionals to develop effective defense strategies against DNS-based phishing attacks.
