Attackers do not rely solely on brute force anymore. They leverage breached credentials, device spoofing, behavioral mimicry, and synthetic identity layering to bypass traditional controls.<\/p>\n\n\n\n<p>The challenge is not authentication failure. The challenge is signal blindness.<\/p>\n\n\n\n<p>Static verification models \u2014 password + OTP + device recognition \u2014 are insufficient against adaptive fraud.
