Ofrak

Once data is unpacked, OFRAK’s Analyzers run automatically to characterize it. This might involve identifying code architectures (ARM, MIPS, x86) or calculating checksums.

The framework tracks dependencies, so when you change one byte inside a CPIO archive, Ofrak knows to recompute the archive's checksum and re-insert it into the UEFI volume that contained it. Once data is unpacked, OFRAK’s Analyzers run automatically

If you are working with firmware security, bootloaders, or any scenario where you need to modify a binary without its original build environment, Ofrak is worth the investment. Start with their official tutorials on unpacking a simple U-Boot image, then work your way up to patching an encrypted Android boot image. If you are working with firmware security, bootloaders,

Ofrak is built around a modular, scriptable pipeline. Its architecture can be broken down into four key layers: Its architecture can be broken down into four key layers:
