An insider data breach at Verizon has compromised the personal information of more than 63,000 employees, nearly half of the company’s global workforce.

The telecommunications giant disclosed the incident in a Data Breach Notification with the Office of the Maine Attorney General, revealing that the breach occurred around September 21, 2023, due to unauthorized access by an employee.

How was the breach discovered and what information was compromised?

Although the breach occurred in September, Verizon uncovered it nearly three months later, on December 12, 2023.

The compromised information includes:

  • employees’ full names
  • street addresses
  • Social Security numbers
  • National ID
  • Gender
  • Union affiliation
  • Date of birth
  • Compensation information

Verizon assures that there is no evidence of misuse or external sharing of the impacted information, according to SEC Alerts.

In response to the breach, Verizon has offered free identity protection and credit monitoring services to the affected employees for two years.

The company also recommends that employees vigilantly monitor their credit reports and review account statements to detect any irregularities.

Verizon is a leading global telecommunications company with 117,000 employees across 150+ countries and global revenues of $134 billion in 2023.
