Data breach at tax agency allowed companies to peek in on competitors’ data
A data mix-up on a state tax portal inadvertently made private data from about 16,500 business taxpayers viewable to other companies, potentially even competitors. The breach lasted from Aug. 7, 2017, through Jan. 23, 2018, and allowed some companies to view other business’s names, federal employer identification numbers, tax payments, and other data, according to the Massachusetts Department of Revenue.
