When Deepfakes Steal $30M: The New Edge of Cybercrime
Episode 58
AI is transforming both sides of the cybersecurity cat-and-mouse game. Attackers are using LLMs to scale impersonation, phishing, and even deepfake fraud—while defenders are racing to automate detection and takedowns at the same speed.
In this episode, a16z partner Joel de la Garza talks with Kevin Tian, cofounder & CEO of Doppel Security (and former Uber engineer), about building in this new landscape. They cover:
- Why outsider founders sometimes build the most effective security companies
- The “3 V’s” framework for today’s social engineering attacks: volume, velocity, variety
- How Doppel uses reasoning models and reinforcement fine-tuning to cut false positives and improve precision
- Simulation tools like “vibe phishing” to train employees on real attacker tactics
- The shift from manual cyber-intelligence services to AI-driven, software-margin businesses
- Why the biggest bottleneck now isn’t model cost—but engineering time to deliver the right context
If you’re building security products or exploring how AI can automate tough edge cases, this is a ground-level look at what’s working—and what comes next.
