Scenario 1 – Change payroll account information Attacker sends spoofed email impersonating an employee to the HR to change the salary account details to Attacker’s account number. Salary account details are modified by the HR based on the mail.

Scenario 2 – Authorize a fund transfer impersonating a high-profile executive or an authorized user Attacker sends a spoofed email impersonating to be a high-profile executive or an authorized user, requesting the finance department to initiate a fund transfer to attacker’s account. Based on this email, the finance department performs the transfer to the attacker’s account without further checks.

Scenario 3 – Account compromise Account compromise may occur due to a malware or phishing or via social engineering attack where the perpetrator Impersonates IT personnel in the target user’s company and the user discloses credentials without further verification. Attacker connects to authorized user’s email account with the compromised credentials and sends an email to transfer funds to attacker’s account number.
