Cyber Criminals Target Employees with W-2 Phishing Scam
The W-2 Phishing Scam and Understanding Social Engineering
It’s tax season in the United States, and many organizations have just prepared their employee’s W-2s. You may have recently received the form in an electronic or paper format and are prepared for the opening day of tax filing on January 29th. Tax season also provides an opportunity for cyber criminals to attack your organization with a social engineering technique commonly referred to as phishing.
Criminals are interested in collecting W-2s as the information on the form enables them to file many fraudulent tax returns, claim refunds and in many cases, avoid detection for months until the legitimate tax return is filed.
Phishing Attacks Are Increasing
The last few years have seen the rise of “W-2 scams” (a type of phishing attack) where criminals, posing as the company CEO or a similar executive, email one or more employees in payroll, accounting, or human resources with an urgent request to send all W-2 forms.
Typically these requests will be written so they appear to have been sent from one of the organization’s executives and the message will often contain a comment about being unreachable along with an immediate, pressing need for the W-2s. The sense of urgency and appearance of coming from a corporate executive are common psychological tactics used in phishing scams to increase the response rate.
How do Cyber Attackers Identify the Employees to Target with Their Phishing Emails?
This information is often found on the internet. Corporate websites may be disclosing the roles of those who would be ripe to target while in other cases, the attackers will comb LinkedIn or other public forums to find job tiles, email addresses and other details that are useful in crafting a believable message that spurs the recipient to respond.
Preventative Steps to Protect Against Phishing
- Limit the number of people within the organization who can access or process W-2s and other sensitive documents.
- Have the team responsible for managing email modify the subject line of messages to clearly identify those that come from outside the organization.
- Create a validation process that enables employees to verify the legitimacy of a request involving sensitive information.
- Call, text or message (do not respond to the email by using reply) the apparent sender to confirm the request. If email must be used to make contact, compose a separate email to the executive impersonated in the email and make sure you’re not replying to the attacker before you send the confirmation.
- Raise awareness – send announcements about these and other scams and train employees so they know how to respond.
- Do not click links contained in the email or open any attachments accompanying the email.
- Contact your IT or Security organization to alert them about the phishing email.
