This week, we are joined by Jon Williams, Vulnerability Researcher from Bishop Fox, discussing "Tearing Down (Sonic)Walls: Decrypting SonicOSX Firmware." Bishop Fox researchers reverse-engineered the encryption protecting SonicWall SonicOSX firmware, enabling them to access its underlying file system for security research. They presented their process and findings at DistrictCon Year 0 and released a tool called Sonicrack to extract keys from VMware virtual machine bundles, facilitating the decryption of VMware NSv firmware images. This research builds upon previous work, including techniques to decrypt static NSv images and reverse-engineer other encryption formats used by SonicWall. The research can be found here: Tearing Down (Sonic)Walls: Decrypting SonicOSX Firmware Learn more about your ad choices. Visit megaphone.fm/adchoices
