The online health insurance marketplace servicing residents of Washington, D.C., and staffers and members of the U.S. Congress is facing two proposed class action lawsuits in the aftermath of a hacking incident that affected at least 56,400 individuals.

Some of the data stolen in the incident was posted for sale on the dark web earlier this month (see: Hackers Sell U.S. Lawmaker Data Stolen From Insurance Market).

Both of the lawsuits were filed last week in the U.S. District Court for the District of Columbia, and each makes similar allegations against the DC Health Benefit Exchange Authority, including that the entity was negligent in failing to secure sensitive information of the plaintiffs and class members.
