Chicago-area woman Chandra McPherson is the named plaintiff in a class-action lawsuit filed this week in federal court in Chicago. Similar lawsuits have been filed in other states.
The 31-page Chicago lawsuit seeks unspecified damages in one of the largest data breaches in U.S. history.
Last week, Target revealed that up to 40 million credit and debit accounts may have been stolen. Target says the breach involved U.S. store purchases between Nov. 27 and Dec. 15.
A message seeking comment from Target's Minneapolis headquarters Thursday wasn't immediately returned. A Target statement Monday said it "remains committed to sharing information about the recent data breach with all who are impacted."
