This brief tutorial will show you how to go about analyzing a raw binary firmware image in Ghidra.
I was recently interested in reversing some older Cisco IOS images. Those images come in the form of a single binary blob, without any sort of ELF, Mach-o, or PE header to describe the binary.
While I am using Cisco IOS Images in this example, the same process should apply to other Raw Binary Firmware Images.

常設CTFで遊んでたらPwnable系の問題を解いてるうちにいろいろと勉強になったのでまとめます。
PwnableとはCTFのジャンルの1つで、プログラムの脆弱性をつき、本来アクセスできないメモリ領域にアクセスして操作し、フラグを取得する感じの問題です。
別名としてExploitがあります。
