■ Miyabull's Unique Triple Blocking System
------------------------
In addition to the conventional blacklist detection method, Miyabull incorporates its own unique heuristic detection and AI detection. This triple blocking system, powered by three engines, further enhances detection capabilities.
[Blacklist Detection]
This system uses a URL list confirmed through reports to public institutions, etc. Miyabull issues warnings for URLs on the list. However, it cannot block fraudulent sites with the same content but different URLs.
[Heuristic Detection]
Heuristic detection addresses the problem of blacklist detection, which cannot block fraudulent sites with the same content but different URLs. Its mechanism involves analyzing the characteristics of accumulated fraudulent sites and blocking them using a detection engine that automatically determines the content.
[AI Detection]
By automating the analysis and tuning of fraudulent sites—the basis of heuristic detection—through machine learning, it reinforces conventional heuristic detection and provides detection capabilities that can keep up with the rapidly changing methods of criminals.
