We are happy to announce support for UBI images and the UBIFS file system. The new UBI Format package lets you inspect UBI volumes and browse UBIFS file systems directly within the application.

UBI (Unsorted Block Image) is a volume management layer for raw NAND flash memory, widely used in embedded Linux devices such as routers, IoT hardware, industrial controllers, and consumer electronics. A UBI image contains one or more logical volumes that may hold kernel images, SquashFS partitions, or UBIFS file systems. UBIFS is a log-structured file system designed specifically for UBI volumes, featuring a B-tree index and transparent data compression. 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.
