Sessions
In this presentation, we will explore Window’s Data Protection API (DPAPI) to gain an understanding of how it works and how it is exploited to dump credentials. DPAPI is utilized to encrypt data on a Windows system and is used by various applications like Chrome and Edge’s password managers. We will explore the code and requirements used for data encryption and decryption. Along with ways to abuse DPAPI, such as establishing Domain Persistence through extracting Domain Controllers’ Backup Key.
