Anatomy of a Breach Report
A breach isn't just a leak. It's a weapon, repurposed again and again.

Cyberattacks and fraud are growing in sophistication and intent, targeting the very structure of our organizations. To achieve this, threat actors are studying us, probing every corner of our business, from third-party vendors to forgotten cloud and IT assets, to find our weakest points to exploit.
With cybercriminals now behaving like data scientists to unearth these valuable insights to fuel cyberattacks and fraud, unstructured data cannot be ignored. Internal documents, credentials, and supplier communications all can be pieced together to paint a detailed picture of how we operate.
That’s why accurately assessing the impact of a breach now means uncovering not just if data was leaked, but what was leaked, how it can be used, and who might be affected.
Analyzing 141 million files across 1,297 data breaches, The Anatomy of a Breach is the biggest ever content-level analysis of breached datasets, exposing the monumental risk that unstructured data poses to organizations, their employees, and customers.
