A major challenge in a case like this is getting the class certified, says an attorney close to the case.

The lawsuit alleges the insurer covertly collected the data.

"I'm hoping that insurance companies take a look at... the way they handle cancellations, and make some changes."

Other major insurers, including USAA and The Hartford, have faced similar allegations this year.

The lawsuit was filed on November 4 in Massachusetts Superior Court.

The carrier seeks more than $600,000 in total recovery from the defendants.

Even their lawyer acknowledges the plaintiffs have a difficult road ahead in litigation.

Scammers allegedly used a spoofed email to masquerade as a law firm and steal settlement money.
