The specific details regarding how the breach occurred and the exact types of personal information involved have not been publicly disclosed by GSB. However, any compromise of data managed by a law firm could potentially expose a wide range of sensitive personal details, given the nature of their work and the extensive information they collect.

For those affected, the exposure of personal information can lead to various risks, including an increased likelihood of identity theft, financial fraud, and targeted phishing attempts. It is prudent to remain vigilant and take steps to protect your personal information following such an incident.

Under Massachusetts law, entities that collect and store personal information are required to implement and maintain reasonable security measures to protect that data.
