BIN Files Apple Community

A study of the entropy across a firmware image, therefore, can reveal encrypted or compressed sections. Before trying to identify the sections with file systems, to understand their contents, it is useful to identify the format of the firmware image.

The board comes with inbuild bootloader which means this board cannot be flashed again since the hardware is locked. We would suggest you contact to our partner for more information on the same. This implies we have loaded the file at the correct address with proper memory mapping. The same information can also be found in the processor memory map from the device datasheet. All of this indicates that we have not loaded the file at the right address. Had we specified the correct address when loading the file in Ghidra, at least some of the strings would have a reference pointing at them if not all.

firmware bin file

Binwalk can scan a firmware image to search for different embedded file types and file systems. When a gamer download the firmware from here. downloads a game they purchased from, the download package includes a setup.exe file and one or more BIN files. Each BIN file contains game data that the game installer references to install the game. NAND.bin - An encrypted file that stores the contents of a Wii's NAND Flash Memory, including save data, miis, downloaded channels, and the Wii menu. Some gamers that dump game ROM data to BIN files compress them in .ZIP archives to reduce their size. A BIN file is a compressed file saved in the MacBinary format that stores a finder header, data fork, and resource fork. It ensures the Macintosh Hierarchical File System (HFS) resource fork and data fork are both kept in one file when transferring Macintosh files via the Internet, email, FTP, or portable media.

So I used Binwalk again and it showed some possible OS offsets. I tried extracting them with dd like ↓ but kept getting garbage. The Cisco IOS seemed like the most viable offset, but it doesnt even give the correct header. Im trying to extract the Filesystem if possible, or at least extract the OS to load in IDA. I was thinking it might just be one big executable OS file, but wasn't so sure. There seems to be many possible OS strings like Cisco IOS, Broadcom firmware header, eCos RTOS, etc. I'm not aware of an app that can extract files from a .BIN file.
