While the official filing does not specify the exact categories of information compromised, law firms like McClallen Law routinely handle a wide array of sensitive data. This includes confidential client files, communications, and other personal information. The breach means this data was within reach of unauthorized parties.

The exposure of your personal information, regardless of specific type, creates an elevated risk of various harms, including identity theft, fraud, and privacy violations. Under Massachusetts data privacy laws, McClallen Law had a legal duty to implement strong security measures to protect this sensitive data.

Can I sue McClallen Law over the data breach?
