Substitute Teacher Service Data Breach Class Action

At Console & Associates, our data breach lawyers are closely examining the recent Substitute Teacher Service data breach. This data breach was disclosed following a cyber security incident at Substitute Teacher Service, which may have affected an undetermined number of individuals, potentially exposing sensitive personal identifiable information.

What Happened?

A recent report from the Massachusetts Attorney General's Office states that the Substitute Teacher Service data breach occurred due to a cyber security incident. Based on available information, unauthorized parties gained access to sensitive information that had been provided to the company.

The specific nature of this breach remains somewhat unclear. While it may have resulted from a direct cyberattack against Substitute Teacher Service's systems, there's also the possibility this incident originated from a third-party data breach at one of STS's vendors or business partners. Notably, the company has not issued a public press release or posted information about the incident on their website.

Upon discovering the unauthorized access, Substitute Teacher Service conducted an investigation and review of the compromised files. The sensitive information exposed in this breach varies by individual but potentially includes:

• Full names
• Social Security numbers
• Financial account information
• Driver's license numbers

Data breach letters were sent out by Substitute Teacher Service on March 14, 2025, informing affected individuals about the nature of the incident and specifying which types of their personal data were compromised.
