FAQs

Account takeover fraud is a form of identity theft where a bad actor gains unauthorized access to a victim’s online account.

The process unfolds in three stages:

1. Account Compromise: The fraudster breaches the victim’s account.
2. Access Lockout: They alter account details to lock out the rightful owner.
3. Fraudulent Activity: The compromised account is used for unauthorized transactions or abuse.

Targets include:

• Banking and financial accounts
• Ecommerce accounts
• Social media profiles
• Loyalty program accounts
• Government benefit accounts

Account takeover attacks often begin with one of the following techniques:

• Credential Stuffing: Using botnets to test stolen username/password combos.
• Phishing & Social Engineering: Emails, SMS, or calls trick users into providing credentials or downloading malware.
• Malware & Keyloggers: Software records keystrokes to steal credentials.
• Brute Force Attacks: Automated tools guess passwords using dictionaries or randomization.

Once inside, fraudsters:

• Change credentials, PII, and security settings
• Add unauthorized users
• Request new cards or conduct transactions
• Abuse consumer protections like Regulation E to extract funds

• Logins from unfamiliar devices or locations
• Access during atypical times

• Multiple failed login attempts in a short time
• Spikes in login frequency

• Changes to personal info or security settings

• Uncharacteristic transactions
• Irregular navigation patterns

• Disabled alerts or unexpected contact info changes

KBA asks users to verify identity via questions based on personal info.

Types:

• Static KBA: User-defined questions
• Dynamic KBA: Data-derived questions

Why it's flawed:

• Adds friction before validating identity
• Data used is often leaked or publicly available

To prevent ATO:

• Monitor for early warning signs
• Deploy layered fraud detection (e.g., device, behavior, biometric signals)
• Avoid outdated auth methods like KBA
