I used Ghidra twice, so that means I'm officially an expert in reverse engineering

Strap in kids, this post is about me physically hacking apart Amazon's Blink Mini to get access to its firmware! No firmware was harmed or modified in the making of this post... yet. Big thanks to Ada and Erin for helping me figure this stuff out! Background I attended the… read more
