Phishing, a longstanding cyberattack technique through which attackers impersonate others to gain access to confidential information, has become immensely popular as of late, hitting an all-time high in December 2021, with attacks tripling since the previous year.

Attacks continue to become more and more sophisticated, with hackers using complex code and complicated processes to successfully breach organizations and stay under the radar.

The attacker can go as far as to sign an email electronically with whatever name and domain they want, but they cannot use the actual email domain of the spoofed entity or their target.

A standard approach to addressing spoofed domains is to compare them to a database of known domains and to look for differences.

This algorithm incorporates the heuristic biological algorithms such as SLAGAN, local alignment, global alignment and translocations, and modifies them in a way that specifically addresses the domain lookalike cybersecurity challenges used in phishing attacks.

Phishing attacks are becoming more and more complex and sophisticated over time.
