This document provides answers to frequently asked questions about Corporate Account Take Over (CAT) fraud. CAT fraud involves tricking business owners into installing malicious banking software that allows criminals to access and steal funds from business accounts. The money is usually sent overseas through wire transfers or money mules. According to law enforcement, Eastern European organized crime groups are primarily responsible for CAT fraud. While businesses of all sizes can be targeted, smaller businesses and non-profits are now common targets. If a business believes they are a victim, they should disconnect their computer and contact their bank immediately.
