Impersonation Is Out of Control. How Doppel Finds It Before You Even Know It’s Happening

Fake LinkedIn profiles. Deepfake audio. WhatsApp scams. Your CEO being impersonated on BlueSky.

Most security tools never even see it.

In this episode, Kevin Tian (CEO & co-founder of Doppel) joins me to break down how modern impersonation campaigns actually work — and why traditional takedown tools aren’t enough.

We dig into:

• Real-world impersonation campaigns targeting F500 execs
• How Doppel maps entire threat infrastructures from a single phone number
• Why your SOC team is blind without cross-channel visibility
• The new threat vector keeping Kevin up at night: fake job candidates

This is one of the most eye-opening conversations I’ve had about modern social engineering. Watch it now.
