Webinar | From FSB Agents Phone Numbers to Addresses: Investigating with District4 Breached Data

Person of interest investigations often come with this challenge: Starting with a name or common alias yields lots of information but with less relevance. Starting with an email address or phone number retrieves results with higher confidence, but in smaller quantity.

Using compromised records for your investigations makes things easier. Compromised records form a database of email addresses, domains, IP addresses, names, passwords, and other personal identifier information, which helps uncover a subject’s online presence, identify threat actors, and determine a company’s breach exposure.

In this webinar, the largest compromised data provider District4 and Maltego come together to demonstrate the breadth and depth breached data can bring to your investigations. We will start off with a set of alleged leaked phone numbers of FSB agents, explore over 40 billion records provided by District 4, and end with physical addresses of FSB-owned buildings in shockingly controversial places.

In this webinar, you will learn:
