# Account Takeover Attacks Are Surging — Stop Them With AI-Powered Fraud Defense

Nearly [$13 billion](https://javelinstrategy.com/research/2024-identity-fraud-study-resolving-shattered-identity-crisis) — that’s how much account takeover (ATO) fraud cost businesses in 2023 alone. This isn’t just another alarming stat — it’s a wake-up call for any organization managing user accounts. Industries like e-commerce and financial services are feeling the heat, with ATO attack rates spiking [36%](https://sift.com/index-reports-account-takeover-fraud-q3-2024) and [10%](https://sift.com/index-reports-account-takeover-fraud-q3-2024) year-over-year, respectively.

The methods behind these attacks aren’t new: stolen credentials from data breaches, phishing attacks, and malware are still the go-to tools for fraudsters. What is new? The scale, sophistication, and speed of these attacks. And traditional defenses—CAPTCHA, static rules, even MFA—aren’t enough on their own.

### What you need: Real-time, AI-driven fraud defense

That’s where Auth0 + Sift comes in. Together, they deliver real-time, risk-based fraud detection and authentication at scale. With the pre-built integration, businesses can achieve robust ATO defenses quickly and with minimal engineering lift.
