We are happy to announce support for YAFFS and YAFFS2 file system images. The new YAFFS Format package lets you browse and extract files from YAFFS flash dumps directly within the application.

YAFFS2 (Yet Another Flash File System 2) is a log-structured file system designed for NAND flash memory. It is widely used in embedded Linux devices such as Android phones, routers, set-top boxes, IoT hardware, and industrial controllers. YAFFS stores data in fixed-size chunks (pages) interleaved with spare (out-of-band) areas that contain metadata tags. Having native support in Cerbero Suite means analysts can inspect firmware dumps and flash images encountered during security research, vulnerability assessment, or forensic investigations without needing external tools or knowing the NAND geometry parameters.
