Over 700 HarborOne debit card holders have already been affected by "fraudulent activity."

HarborOne Senior Vice President Dave Tryder spoke with the Taunton Gazette about the hack that has affected customers throughout Massachusetts and says they are working with local authorities and the FBI to "contain" the current situation.

HarborOne serves customers in 11 Southeastern communities including, Raynham, Mansfield, Brockton, Easton, Bridgewater, Middleboro, Abington, Attleboro, Canton, Plymouth and Randolph.

Tryder did not say what the fraudulent activity was or how much money had been stolen, but did say all customers affected were going to be notified as of Wednesday night.

Rayham police were also investigating multiple reports of town residents' bankcards being hacked and money being withdrawn from their accounts, but according to WCVB it is unclear whether the two incidents are related.
