First Whitney Bank and Trust Corporate Account Takeover
What is Corporte Account Takeover?
“Corporate account takeover” is when cyber-thieves gain control of a business’ bank account by stealing the business’ valid online banking credentials. Although there are several methods being employed to steal credentials, the most prevalent involves malware that infects a business’ computer workstations and laptops.
A business can become infected with malware via infected documents attached to an e-mail or a link contained within an e-mail that connects to an infected website. In addition, malware can be downloaded to user workstations and laptops by visiting legitimate websites – especially social networking sites – and clicking on the documents, videos or photos posted there. This malware can also spread across a business’ internal network.
The malware installs key logging software on the business’ computer, which allows the perpetrator to capture a user’s credentials as they are entered at the business ‘ Bank web site. Sophisticated versions of this malware can even capture token-generated passwords, alter the display of the Bank’s web site to the user, and/or display a fake web page indicating that the Bank’s web site is down. In this last case the perpetrator can access the business’ bank account online without the possibility that the real user will log in to the web site.
Once installed, the malware provides the information that enables the cyber-thieves to impersonate the business in online banking sessions. To the Bank, the credentials look just like the legitimate user. The perpetrator has access to and can review the account details of the business, including account activity and patterns. The cyber-thieves use the sessions to initiate funds transfers, by ACH or wire transfer, to the bank accounts of associates within the U.S. (FWB does require all wire transfers to be done in person).
Prevention, Detection and Reporting for Business Customers
- Reconcile all banking transactions on a daily basis.
- Immediately report suspicious transactions to the bank.
- Stay in touch with other businesses and industry sources to share information regarding suspected fraud activity.
- Utilize account alerts for various transactions types and balance levels.
Computer Security Tools and Practices
- Install dedicated, actively managed firewall. A firewall limits the potential for unauthorized access to a network and computers.
- Install and regularly update commercial anti-virus software on all computer systems.

- Consider installing spyware detection programs.

- Limit administrative rights on user’s workstations.
- Conduct online banking activity from a stand-alone computer from which email and web browsing are not allowed.

- Never leave a computer unattended while using any online banking services and never access online banking from internet cafes or public places.
