The Virginia-based bank confirmed a hacker exposed some 100 million credit card applications and tens of thousands of Social Security numbers and bank accounts.

"While I am grateful that the perpetrator has been caught, I am deeply sorry for what has happened," Capital One chairman and Chief Executive Officer Richard D. Fairbank said in a statement.

"I sincerely apologize for the understandable worry this incident must be causing those affected and I am committed to making it right," he said.

The FBI arrested a suspect in Seattle, identified as Paige A. Thompson, according to The Washington Post.

Thompson is accused of stealing millions of customers' private records and is charged with computer fraud and abuse, the Post reported, citing court documents.

The bank said no credit card account numbers or login credentials were compromised but confirmed about 140,000 Social Security numbers of credit card customers and about 80,000 linked bank account numbers were.

The Post reported the hack is expected to cost Capital One between $100 million and $150 million in the near term.

The bank said it is notifying customers affected by the breach and will offer free credit monitoring and identity protection for those affected.

The scope of the Capital One hack is similar to a massive 2017 breach at Equifax that compromised 147 million Americans' personal information.
