“91% of cyber-attacks begin with a spear phishing email…Spear phishing is an increasingly common form of phishing that makes use of information about a target to make attacks more specific and personal.”

Spear phishing can be achieved by email, text message, or other sources of communication. At times, the hacker may be disguised as a trusted individual with a spoofed, or faked, email address or phone number. These days, you need to double check who you are talking to, especially when dealing with sensitive information.

The IC3 has received complaints reporting cybercriminals are targeting the online payroll accounts of employees in a variety of industries. Institutions most affected are education, healthcare, and commercial airway transportation.
Cybercriminals target employees through phishing emails designed to capture an employee’s login credentials. Once the cybercriminal has obtained an employee’s credentials, the credentials are used to access the employee’s payroll account in order to change their bank account information. Rules are added by the cybercriminal to the employee’s account preventing the employee from receiving alerts regarding direct deposit changes. Direct deposits are then changed and redirected to an account controlled by the cybercriminal, which is often a prepaid card.
