    Impersonation Attacks are on the rise

    Impersonation attacks are among the latest advanced targeted attacks that use email to dupe employees into revealing information or making financial transactions. During impersonation attacks, attackers pose as a CEO, CFO or other high level executive and request an employee to perform a specific action via email. Impersonation attacks like wire transfer phishing often trick users into making wire transfers or revealing sensitive employee data such as payroll information that may be used in identity theft.

    Impersonation attacks succeed by utilizing engineering tactics against users, including display names and domain names that appear to be genuine but are actually well-crafted fakes. Attackers often use personal information found on social media accounts to convince the user that the email has been sent by a trusted individual.

    1In recent years, the number of impersonation attacks has risen sharply, with the FBI estimating a 270% increase in the first eight months of 2015, and the cost of these attacks to the business world has exceeded $2 billion since January 2015.

    To thwart impersonation attacks, a growing number of organizations worldwide are turning to the highly effective phishing protection software provided by Mimecast's email security services.
