What’s in your wallet? For 100 million Capital One card holders and applicants: someone else.

According to a press release issued late last night, Capital One Financial Corporation announced a suspect who infiltrated their system and exposed millions of people’s personal information was arrested by the FBI.

The company claimed that based on their analysis so far, it believes it was unlikely the suspect used any of the hacked information for fraud or made any of those details publicly available.

Per a press release, the banking giant explained no credit card numbers of log-in credentials were exposed and more than 99 percent of Social Security numbers were not exposed.

Here’s what was exposed:

• Customer status data like credit scores, limits, balances, payment history and contact information
• Approximately 140,000 Social Security numbers from credit card customers.
• 80,000 linked bank account numbers of its secured credit card customers.

Customers affected by the hack will be notified by the company.

Six million Canadian customers were also exposed; about 1 million people’s Social Insurance numbers were compromised.
