What is the “Why is deepfake grandparent fraud the fastest-growing scam, and banks have no answer?” problem in 2026?

AI voice clones from a 3-second TikTok now defeat both family trust and bank voice biometrics. Reported losses are climbing in 2026. Banks reimburse selectively.

Who has this problem?

Adults aged 60+ and their families, plus banks under regulatory scrutiny for failing-to-prevent fraud.
