Why This Breach Matters
Technology and software companies often store data on behalf of thousands of businesses, meaning a single breach can expose the personal information of consumers across multiple industries simultaneously. Tech companies also frequently store account credentials — username and password combinations that attackers test across dozens of other websites in automated attacks known as credential stuffing.
Massachusetts residents are protected by M.G.L. c. 93H, which gives you the right to pursue legal remedies when a company fails to adequately protect your data.
