项目说明

OFRAK

OFRAK (Open Firmware Reverse Analysis Konsole) is a binary analysis and modification platform. OFRAK combines the ability to:

OFRAK supports a range of embedded firmware file formats beyond userspace executables, including:

OFRAK equips users with:

See ofrak.com for more details.

GUI Frontend

The web-based GUI view provides a na resource tree. For the selected resource, it also provides: metadata, hex or text na, and a mini map sidebar for quickly na by entropy, byteclass, or magnitude. The GUI also allows for actions normally a through the Python API like commenting, unpacking, analyzing, modifying and packing resources.
