Protecting Employee Data Requests from Identity Theft and Social Engineering

Employee data requests are a normal part of HR operations, whether an employee asks for a copy of a pay stub, a former worker requests their W-2, or someone inquires about benefits information. However, these requests also present an often-overlooked security risk. Cybercriminals and identity thieves have become increasingly sophisticated, impersonating employees, former staff, or even executives to trick HR professionals into disclosing sensitive data. HR teams must handle every data request with care, applying consistent authentication procedures to prevent unauthorized disclosures.

The Growing Threat of Social Engineering
Social engineering is one of the most common tactics used by attackers to gain access to private information. Rather than hacking a system, these criminals manipulate people often targeting HR professionals who regularly handle sensitive personal data. A convincing email, phone call, or even letter can appear legitimate, asking for “urgent” access to payroll documents, benefits statements, or tax forms. Once that data is shared, it can be used for identity theft, tax fraud, or unauthorized access to company systems.

Even seemingly harmless details like confirming an employee’s address or hire date can be enough for an attacker to piece together additional information from other sources. That’s why HR teams should never release any employee data, no matter how routine the request seems, without confirming the requester’s identity.

Steps for Authenticating Requests
The first line of defense is a clear, documented procedure for verifying all data requests. These steps should be applied consistently to both current and former employees:

1. Require written requests through verified channels. All requests should come from an official company email address or, for former employees, through a secure portal or mailing address on record. Requests received through personal email accounts should be treated with caution and verified by phone before processing.
2. Use multi-step identity verification. Before releasing documents, ask for identifying details such as employee ID number, last four digits of the Social Security number, and date of birth. For former employees, request additional information such as their last work location or supervisor’s name.
3. Confirm through a secondary contact method. If a request comes via email, call the phone number on file, not the one provided in the email, to confirm that the employee made the request. Similarly, for phone requests, follow up via a known company email address before fulfilling the request.
4. Restrict access to authorized HR staff. Only trained HR or payroll personnel should handle sensitive data requests. Role-based access controls help ensure that only authorized employees can view or transmit PII or benefits information.
5. Transmit securely. When sharing requested documents, use encrypted email, password-protected files, or secure portals. Never send unencrypted attachments or share data through public cloud links.

Educating HR Staff and Employees
Regular security training is vital. HR professionals should be aware of common social engineering tactics such as phishing, spoofed email addresses, or urgent tone requests. Employees should also know that legitimate HR communications will follow defined procedures, reducing confusion and making fraudulent messages easier to identify.

Why It Matters
A single incident of unauthorized disclosure can have serious consequences, including employee distrust, financial loss, and potential legal liability under privacy regulations such as HIPAA, the CCPA, or state data breach laws.

By establishing and enforcing authentication protocols, HR teams can ensure that sensitive employee information remains secure while still providing efficient service to those who need it. Careful verification and secure communication aren’t just administrative steps, they are essential safeguards that protect both employees and the organization from preventable data breaches.
