In this video, we discuss how to extract firmware from a Linux Router using UART access to the device's bootloader. This device used U-Boot as the embedded system's bootloader which provides us with a way to extract flash memory contents using a few handy U-Boot commands. Then we use a small python script to convert the U-Boot hex dump to a binary file which we can analyze with binwalk. • video on finding UART: • • Finding UART and Getting a Root Shell... • tool to convert u-boot hex dump output to a binary file: • https://github.com/nmatt0/firmwaretools • U-Boot command documentation: • https://u-boot.readthedocs.io/en/late... • IoT Hackers Hangout Community Discord Invite: • / discord • 🛠️ Stuff I Use 🛠️ • 🪛 Tools: • XGecu Universal Programmer: https://amzn.to/4dIhNWy • Multimeter: https://amzn.to/4b9cUUG • Power Supply: https://amzn.to/3QBNSpb • Oscilloscope: https://amzn.to/3UzoAZM • Logic Analyzer: https://amzn.to/4a9IfFu • USB UART Adapter: https://amzn.to/4dSbmjB • iFixit Toolkit: https://amzn.to/44tTjMB • 🫠 Soldering Hot Air Rework Tools: • Soldering Station: https://amzn.to/4dygJEv • Microsoldering Pencil: https://amzn.to/4dxPHwY • Microsoldering Tips: https://amzn.to/3QyKhrT • Rework Station: https://amzn.to/3JOPV5x • Air Extraction: https://amzn.to/3QB28yx • 🔬 Microscope Setup: • Microscope: https://amzn.to/4abMMao • Microscope 0.7X Lens: https://amzn.to/3wrV1S8 • Microscope LED Ring Light: https://amzn.to/4btqiTm • Microscope Camera: https://amzn.to/3QXSXsb • About Me: • My name is Matt Brown and I'm an Hardware Security Researcher and Bug Bounty Hunter.
