Prevent Account Takeover

When a Trusted Customer Isn’t Really Your Customer

A customer logs into their account like any other day. But something’s off. Their shipping address is changed, their payment method updated, and transactions they never made are pending.

Their account has been taken over.

By the time they notice, the damage is done. Their credentials were stolen days, or even weeks, earlier, giving fraudsters time to test stolen logins, access accounts, and drain funds before setting their sights on the next victim.

Account takeovers (ATO) don’t happen overnight. They start with stolen data, weak security gaps, and unchecked fraud patterns slipping through the cracks. That’s why businesses need to detect risk before it escalates, not after customers come forward with complaints.

AtData’s email address intelligence helps you stop account takeovers before they happen, identifying compromised credentials, spotting risky behaviors, and blocking bad actors at the earliest signs of fraud.

How Account Takeovers Unfold

Fraudsters Get Their Hands on an Email Address

Compromised credentials are everywhere. Fraudsters buy stolen email-password combinations from the dark web, harvest data through phishing scams, set up thousands of disposable addresses, or simply test weak passwords until they break through.

How AtData Helps:

• Email activity tracking detects suspicious engagement levels from newly created to dormant accounts with a spike in activity, helping businesses identify accounts that may be vulnerable.
• Domain risk analysis flags emails tied to known data breaches or dangerous domains, giving fraud teams a head start on protecting compromised accounts.

They Test Logins Across Multiple Accounts

Once they have an email and password combo, fraudsters try logging in everywhere: banking apps, e-commerce stores, loyalty programs. If one login works, they’re in. If not, they simply set up a synthetic identity with a new email.

How AtData Helps:

• Risk scoring email addresses attempts in real time, flagging signs of past fraudulent activity or mismatched identity information.
• Behavioral pattern analysis detects unusual usage — like a single email appearing across dozens of sites in rapid succession, or hundreds of tumbled emails across a network of businesses.

They Take Control and Lock the Customer Out

Once inside, fraudsters change passwords, update recovery emails, and swap out necessary details. By the time the real account owner realizes, their data is gone, their funds are spent, and their trust in your brand is shattered.

How AtData Helps:

• Email verification tools confirm whether an updated email address is legitimate and has a history before allowing profile changes.
• Continuous monitoring alerts businesses to newly identified risky emails before fraudsters have a chance to fully take over an account.

Fraudsters Count on Businesses Missing the Signs, AtData Helps You Catch Them

Account takeovers are a direct hit to revenue, security, and customer loyalty. The cost isn’t just lost funds, it’s lost trust. And once customers feel unsafe, they’re unlikely to return.

AtData’s email address intelligence helps businesses:

• Spot compromised credentials before fraudsters use them.
• Detect high-risk login attempts in real time.
• Prevent unauthorized account changes before they lead to full takeovers.

Stay One Step Ahead of Account Takeover Attacks

Fraudsters are always evolving, finding new ways to break in, take over, and cash out before businesses realize what’s happening. That’s why prevention needs to happen at the first sign of risk—not after the damage is done.

AtData makes it possible. With real-time email intelligence, businesses can strengthen fraud models, secure customer accounts, and stop account takeovers before they start. Don’t wait for fraud to happen.
