What is Corporate Account Takeover (CATO)?

Corporate Account Takeover (CATO) is a form of identity theft where thieves typically use some form of malware to obtain a business’ online banking credentials and then initiate fraudulent banking transactions, including wire transfers and Automated Clearinghouse (ACH) payments.

Cyber criminals are increasingly targeting the owners, employees and contractors of small and medium size businesses, municipalities, non-profits and school districts.

How CATO attacks happen

CATO attacks are not aimed at financial institutions; rather they target account holders, specifically the computers and internet connections that are used to access online bank accounts and your employees who are authorized to conduct electronic transactions on your bank account. Your workstations, network connections and account credentials should be secured.

Fraudsters can obtain your online banking credentials through malicious software, phishing, malicious websites, social media, ads from popular websites, or masquerading as a trustworthy person or entity in an electronic communication. These techniques may include clicking a link or opening an attachment in a phishing email, accepting a fake friend request on social networking sites, or visiting a legitimate website that is compromised and installs malware on your computer(s).

Here are some examples:
