JP Morgan Chase, the country's largest banking organization, has recently discovered an area of its internal database that might have been breached during the same attack that was announced to the public in late July.

It seems that hackers with links to Italy or southern Europe gained access to an undisclosed number of the company's servers, suggesting that the last breach was more expansive than previously known.

Spokeswoman for JPMorgan, Kristin Lemkau, told The New York Times, "We are not aware of any new attack." 

Two anonymous bank executives confirmed to the newspaper that Gordon A. Smith, the company's community and consumer banking director, and his associates are working to confirm the extent of the incident. Although JPMorgan appears to have suffered only one breach this year, parts of it were apparently complex enough to evade detection for some time. 

In July, hackers successfully accessed dozens of JPMorgan's servers and browsed information on more than one million customer accounts.This resulted in a federal investigation and mandatory, regular updates to the Federal Reserve. The bank reportedly believes it has secured all its systems.

To protect your business from a breach, be sure to monitor your software and scan your internal systems frequently. Also monitor your company's data reports and take immediate action if you notice any incorrect or foreign information, and tell your employees to use complex, hard-to-guess passwords to decrease your likelihood of being hacked. Finally, use credit card payment software that you trust to keep you and your customers secure. Data breaches can be costly, especially for small businesses, so take every preventative measure available to avoid becoming a victim.
