On July 29, 2019, former Amazon Web Services (AWS) software engineer Paige Thompson allegedly hacked into Capital One’s server through a firewall misconfiguration and stole 140,000 Social Security numbers, 80,000 bank account numbers, and millions of credit card applications.
The data breach was one of the largest thefts of bank information to date, and Capital One estimates up to $150 million in costs related to the hack, including customer notifications, credit monitoring, and legal support.
