11.2 million subscribers' data exposed at US healthcare company

Synopsis

In March 2015, the healthcare provider revealed it had discovered a breach in January that affected as many as 11.2 million subscribers, as well as some individuals who do business with them. The breach compromised subscriber data including names, birth dates, Social Security numbers, bank account information and addresses.

ThreatConnect blog indicates that the prennera[.]com domain may have been impersonating the healthcare provider suggesting the attackers used a character replacement technique replacing the “m” with two “n” characters within their faked domain.

Several lawsuits were filed against the company for failing to disclose the breach in a timely manner, they waited roughly six weeks to tell victims that their data might had been exposed.
