Account Takeover Fraud Explained

What is Account Takeover? Account takeover (ATO) fraud occurs when an account owner's credentials are compromised by phishing, malware, or a data breach in which an attacker gains unauthorized access. Accounts frequently targeted by account takeover breaches occur on financial platforms such as banks and credit card institutions — but can also affect other platforms with sensitive user data.

2023 has already shown a 9% increase in account takeover fraud — causing over $17 billion in losses. Platforms will continue to be breached and every day new data is compromised online. This exposes millions of users per day to increased risk for losing access to their accounts through credential stuffing attacks. Bank account takeover is especially popular as cybercriminals prefer financial incentives as they breach accounts.

Stop Credential Stuffing Attacks

Confidently detect credential stuffing attacks without impacting the user experience for legitimate user accounts. IPQS scores over 300 data points about a user's behavior to identify when stolen user data or unauthorized access is attempted for any account on your network. IPQS provides account takeover protection by detecting geolocation issues, such as when a user spoofing their location or in a different location than an account typically is active in. Instantly screen users during registration or login with live credential stuffing attack prevention.

Credential Stuffing Mitigation

Prevent credential stuffing with real-time monitoring powered by IPQS account takeover fraud detection. Personal data for thousands of accounts are being leaked and sold on the dark web everyday. Quicky deploy industry leading credential stuffing mitigation across your site to detect "cred stuffing" attacks which could allow bad actors to gain access to legitimate user accounts.

Account Takeover Prevention

IPQS uses a mixture of our malicious URL scanner technology and advanced domain reputation to accurately prevent credential stuffing attacks. Once a user has gained access to an account through account takeover attacks, they will quickly take advantage of the credentials to execute financial transfers, asset sales, and attempt to charge unauthorized purchases. Time is key here as the hacker typically has limited time before a client recognizes a suspicious login. Cybercriminals will quickly initiate the transfers, while doing their best to blend with a normal user's behavior patterns.
