We all see and hear about breaches left and right from various companies and organizations. Breaches normally resulting in massive dumps of usernames, passwords and other sensitive information that's released through public and private channels. This presentation will review how both malicious threat actors and security companies are using this data and how. This is where a tool called Sentry MBA comes into play, the newest ‘dark net’ tool actively being used to leverage previously compromised data. During this talk we will provide an overview of the tool, its capabilities, the darknet community that supports it, and details about its requirements and use cases.
