They employ techniques such as 'Extension Hollowing' to replace legitimate extensions with malicious versions that capture wallet credentials. The campaign is centralized, with most malicious domains resolving to a single IP address, and it has expanded to target other browsers while utilizing AI-generated code to enhance scalability and evade detection.
