Within days of Excellus Blue Cross Blue Shields’ (Excellus) announcement that its data had been accessed by a hacker through a “sophisticated” cyber-attack, two law firms teamed up to file a proposed class action suit last Friday against Excellus on behalf of three named plaintiffs. The suit seeks to certify both a nationwide and New York state class of plaintiffs. The suit includes allegations of negligence and breach of contract, and further alleges that two years of credit monitoring for children who were affected by the breach is insufficient.

The suit was filed in U.S. District Court in Rochester and seeks unspecified damages.

Meanwhile, the CEO of Excellus has been questioned by New York state Senator Michael Nozzollo, whose district includes Rochester, NY, where Excellus is located, and he has posted his list of questions to Excellus on his website.
