New York Attorney General Letitia James on Tuesday announced her office will begin an immediate investigation into the data breach at Capital One, which is believed to have exposed the personal information of 100 million customers.

“It is becoming far too commonplace that financial institutions are susceptible to hacks, begging the questions: Why do these breaches continue to take place? And are companies doing enough to prevent future data breaches?” James said in a statement.

“My office will begin an immediate investigation into Capital One’s breach, and will work to ensure that New Yorkers who were victims of this breach are provided relief. We cannot allow hacks of this nature to become every day occurrences.”

A 33-year-old Seattle woman has been arrested and charged with computer fraud.

The Capital One data breach comes after last week’s settlement with Equifax, the credit bureau whose data breach resulted in the exposure of personal data for more than 147 million people.
