Deloitte Data Breach

Deloitte has reported a data security incident involving unauthorized access to an employee’s personnel account, which may have exposed sensitive information, including the name and Social Security number of a New Hampshire resident. The breach, which occurred between February 13, 2026, and February 18, 2026, resulted from an impersonation attack where an unauthorized individual gained access to the employee’s account and potentially exposed personal data.

Deloitte Data Breach Investigation

On February 13, 2026, an unauthorized person impersonating a Deloitte employee called the company’s global call center and, using the correct employee details, reset the employee’s access credentials. This allowed the unauthorized individual temporary access to the employee’s Deloitte personnel account.

Upon discovering the unauthorized access on February 18, 2026, Deloitte immediately reset the employee’s access credentials and initiated an internal investigation to assess the full scope of the incident. The investigation revealed that the unauthorized party may have accessed the employee’s name and Social Security number.

Deloitte confirmed that this breach affected a New Hampshire resident and initiated a formal notification process, which began with verbal discussions on February 20, 2026. A written notice will be sent to the affected individual by April 3, 2026.

When Did This Breach Occur?

The breach occurred between February 13, 2026, and February 18, 2026, during which the unauthorized access to the employee’s personnel account was active. Deloitte responded quickly, resetting the credentials and launching an investigation as soon as the breach was detected.

What Information Was Breached?

The breach potentially exposed the following personal information:

• Full name
• Social Security number

Deloitte has indicated that it is not aware of any identity theft or fraud resulting from this incident. However, as a precautionary measure, the company is offering protective services to the affected individual.

What You Can Do

If you were affected by this breach, Deloitte recommends the following steps to protect yourself from potential identity theft or fraud:

• Monitor Your Credit Reports: You are entitled to one free credit report annually from each of the three major credit bureaus. Review your credit reports for any signs of unauthorized activity by visiting www.AnnualCreditReport.com.
• Place a Fraud Alert: You may place a fraud alert on your credit file by contacting one of the three credit reporting agencies. A fraud alert warns creditors to verify your identity before issuing new credit or making changes to your existing accounts.
• Consider a Credit Freeze: You have the right to place a credit freeze, which prevents creditors from accessing your credit report altogether. This is a strong measure to prevent unauthorized accounts from being opened in your name.
• Enroll in Identity Protection Services: Deloitte is offering a one-year membership to Experian’s IdentityWorksSM, which includes identity restoration and fraud detection services. You can activate these services through the instructions provided in your notification letter.
