Fall ’25 Fraud Report insights: The voice verification shortfall

Videos & Webinars
0:00 / 0:00
Voice is becoming the new weak link in real-time social engineering scams. Not because of deepfakes, but because many financial institutions (FIs) still treat voice as “the truth” without weighing device, behavior, or location signals.

Entersekt’s latest fraud report shows how attackers easily turn voice verification into another relay attack, mirroring today’s OTP and push-fatigue scams.

Watch this webinar recording to understand what’s working, where gaps remain, and how FIs can strengthen authentication with Context Aware™ Authentication, from Entersekt, and stop real-time scams before they succeed.

Highlights include:

  • Why real-time social engineering, and not deepfakes, is driving the next wave of fraud.
  • How attackers bypass voice biometric flows using simple relay tactics.
  • What strong device binding, behavioral intelligence, and contextual risk can catch that voice alone never will.
  • What a modern, resilient, multi-signal authentication design looks like in 2026.
