We are happy to announce support for JFFS2 file system images. The new JFFS2 Format package lets you browse and extract files from JFFS2 images directly within the application.

JFFS2 (Journalling Flash File System v2) is a log-structured file system designed for raw NOR and NAND flash memory. It is widely used in embedded Linux devices such as routers, access points, IoT hardware, industrial controllers, and consumer electronics. JFFS2 stores data as a sequential log of nodes on flash, with each node carrying file metadata, directory entries, or compressed data fragments. 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.
