Account Takeover

Account takeover is a lucrative business for cybercriminals, as accounts can contain valuable information and or be used to launch spam or abuse campaigns. As data breaches proliferate, stolen credentials are becoming easier and cheaper to purchase on the dark web. DataVisor’s Unsupervised Machine Learning Engine analyzes all accounts and events simultaneously, allowing it to detect the hidden connections between hijacked accounts, even when each account is not suspicious in isolation. This allows it to detect the accounts without training data or labels, even as attackers use sophisticated and evolving tactics to evade detection.

How Attackers Take Over Accounts Without Being Detected

Massive Bot Armies

Fraudsters use armies of bots to test millions of stolen credentials or access accounts with commonly-used passwords.

IP Obfuscation

Fraudsters utilize proxies, VPNs, or cloud-hosting services to evade IP blacklists and appear as multiple legitimate users.

Device Obfuscation

Fraudsters utilize mobile device flashing, virtual machines and scripts to appear as though the login events are coming from different devices.

Why Unsupervised Machine Learning for ATO Detection

Modern account-takeover attacks are coordinated and distributed, using stolen credentials and detection-evasion tactics. Because traditional fraud solutions only analyze each account in isolation, they are often unable to effectively detect these attacks. DataVisor’s Unsupervised Machine Learning Engine analyzes all user accounts and events at the same time, uncovering the hidden connections between them. This allows it to detect stolen accounts without training data or labels, even if there is nothing suspicious about the account in isolation.

Account Takeover Fraud: The Anatomy of an ATO Attack

Account takeover fraud fuels the underground fraud-as-a-service economy with compromised accounts, which are sold or exchanged for a variety of downstream attacks. Since these accounts are created by real users (unlike mass-registered fake accounts), they often contain valuable information such as financial data, and their activities are less likely to raise the suspicion of security solutions. Learn about the techniques attackers use to take over accounts en masse.
