PORTLAND, Maine (6/19/08)--A federal judge in Portland, Maine, has set a meeting July 10 with lawyers in the class-action data-breach lawsuits filed against grocery store chain Hannaford Bros. U.S. District Judge D. Brock Hornby will meet with attorneys before deciding which of two groups will be lead plaintiffs in the case (Business Digest June 18). About 23 lawsuits were filed in four states over the breach, which affected customers of more than 300 stores in New England and Florida. Those cases are being consolidated under the federal court's multi-district litigation program in the Maine court (News Now June 11). The lawsuits stem from a breach from Dec. 7, 2007, to March 10, which allowed hackers to steal the credit and debit card numbers of 4.2 million Hannaford customers while they swiped the cards for authorization of purchases at grocery stores. It was the first major breach of a system that was compliant with industry standards. Credit union members were among those whose cards were compromised. In Maine, about 68 credit unions reissued more than 100,000 credit and debit cards to try to limit the amount of fraud (News Now March 24).
