Some customers of Suffolk County National Bank found their accounts hacked over the weekend.
Most customers who spoke with News 12 Long Island say the fraudulent withdrawals were made at ATMs primarily in Queens over the long holiday weekend.
Ashley Kjarbo, of East Patchogue, told News 12 Long Island that more than $1,900 was taken from her account at two separate ATMs.
Bill Mayer, of Shoreham, also said that his card was hit for more than $900.
It is still unclear how many customers were affected by the breach or how much money was taken from Suffolk County National Bank accounts.
Bank officials have not returned calls to comment about the fraudulent withdrawals.
