Capital One Data Breach Details: 10 Things to Know

Capital One Financial Corporation has discovered a massive cybersecurity breach that has affected 100 million individuals in the United States and approximately 6 million in Canada. The breach involved a misconfigured Web application firewall (WAF) on Amazon Web Services (AWS).

The alleged Capital One hacker is a former Amazon employee. For its part, Amazon is striving to distance itself from the breach. A spokesperson for AWS told Newsweek:

“AWS was not compromised in any way and functioned as designed. The perpetrator gained access through a misconfiguration of the web application and not the underlying cloud-based infrastructure. As Capital One explained clearly in its disclosure, this type of vulnerability is not specific to the cloud.”

It’s the latest in a long list of data breaches and information leaks involving misconfigured AWS cloud buckets.
