What is Corporate Account Takeover?

A fast growing electronic crime where thieves typically use some form of malware to obtain login credentials to Corporate Online Banking accounts and fraudulently transfer funds from the account(s).

Malware

  • Short for malicious software, is software designed to infiltrate a computer system without the owner’s informed consent
  • Malware includes computer viruses, worms, trojan horses, spyware, dishonest adware, crimeware, most rootkits, and other malicious and unwanted software.
  • Domestic and International Wire Transfers, Business-to-Business ACH payments, Online Bill Pay and electronic payroll payments have all been used to commit this crime

How Does It Work?

  • Criminals target victims by scams
  • Victim unknowingly installs software by clicking on a link or visiting an infected Internet site
  • Fraudsters begin monitoring the accounts
  • Victim logs on to their Online Banking
  • Fraudsters collect login credentials
  • Fraudsters wait for the right time and then depending on your controls—they login after hours or if you are utilizing a token they wait until you enter your code and then they hijack the session and send you a message that Online Banking is temporarily unavailable
