Understanding the Main Street Bank Data Breach

If you're a customer of Main Street Bank, you may have heard about the recent security incident that occurred between July 5, 2022, and August 22, 2022. During this period, there was a security breach of merchants' payment card environment which led to the potential compromise of card data, specifically card names, numbers, and expiration dates. It's important to note that, as of now, there's no evidence to suggest that personal information such as social security numbers or Main Street Bank account numbers were accessed.

Main Street Bank has taken this matter very seriously and has already begun implementing measures to safeguard affected customers. For those who might be concerned about their card details, the bank is offering the option to visit a branch for an instant issued card or to have a new debit card mailed, which should arrive within 10-14 business days.

Recommended Actions for Affected Customers

  1. Monitor Your Account Statements: Keep an eye on your account statements for the next 12-24 months and promptly report any suspicious transactions to the bank.

  2. Use Online Banking: Leveraging Main Street Bank's internet banking services can help you keep track of account activity and enhance the security of your account.

  3. Report Unauthorized Transactions: If you spot any unauthorized transactions, inform the bank immediately. Remember, state and federal laws protect consumers from losses due to fraud.
