W-2 phishing season is just a few weeks away. For the past several tax seasons, cyber criminals have duped hundreds of payroll departments into providing W-2 information on their employees, which results in the filing of fraudulent tax returns and other identity theft issues. These attacks are incredibly disruptive to employees, extremely expensive for employers and are completely avoidable with some training.
The typical W-2 phishing email purports to be from a high-level executive and asks the payroll employee to provide W-2 or other tax-related information either by replying to the phishing email or by sending the information to another email address. In many instances, the request for the information appears to be urgent, which forces the employee to act quickly. These messages can be very convincing. The emails often contain the actual signature block of the executive or a different indicator that makes the employee believe that the email is authentic.
Employees should be trained to examine emails carefully for signs of phishing and to think twice before sending any sensitive information. Some tell-tale signs can include an unfamiliar email address (e.g. [email protected] instead of the president’s actual email address: [email protected]) or the use of odd or overly formal language. Companies should also implement a policy that either no W-2 information will be requested via email or require that employees verify any email request for W-2 information regardless of the apparent urgency in the message. Verification could include contacting the sender via telephone or by starting a new email thread to confirm the validity of the request. Finally, any such sensitive information that is emailed in response to a verified request should be sent through a new message created by the sender to ensure that the appropriate recipient receives the message (i.e., do not reply to the emailed request).
The IRS has instructed organizations receiving W-2 scam emails to forward them to [email protected] and indicate “W2 Scam” in the subject line and also to file a complaint with the FBI’s Internet Crime Complaint Center (IC3) at https://www.ic3.gov/default.aspx.
In the unfortunate event that your company falls prey to a W-2 or other phishing attack, you should contact legal counsel immediately to assist in implementing strategies to minimize damage and to determine legal obligations. Immediate action is the key to minimizing damage in W-2 phishing attacks as well as all other data breach situations.
