The Nature of the Breach
In 2019, Capital One, a major financial institution, experienced a significant data breach that affected millions of individuals. The attackers gained unauthorized access to sensitive personal information, including names, addresses, Social Security numbers, credit card numbers, and credit scores. This incident highlighted the vulnerability of even large and well-established organizations to cyberattacks.
Data Compromised and Affected Individuals
The breach exposed a vast amount of personal data belonging to over 100 million individuals. The compromised information included:
- Names
- Addresses
- Social Security numbers
- Credit card numbers
- Credit scores
- Dates of birth
