☁️ 一些免费的云资源

  • IaaS指提供系统(可以自己选)或者储存空间之类的硬件,软件要自己手动装。PaaS提供语言环境和框架(可以自己选)。SaaS只能使用开发好的软件(卖软件本身,如税务会计、表格文字处理)。BaaS一般类似于非关系数据库,但各家不通用
  • 云服务的特点:零前期成本 & 按需付费 & 弹性(类似于租,可随时多加、退掉;但没有残值)、高可用(放在机房中,不同AZ间水电隔离)

如果你想补充内容,建议优先给 free-for-dev 提PR,还能混个高星repo的contributor,没必要加到本列表里。
If you want to make improvements, I would recommend you contributing to free-for-dev rather than this list.

Reversing Cisco IOS Raw Binary Firmware Images with Ghidra

Reversing Raw Binary Firmware Files in Ghidra

This brief tutorial will show you how to go about analyzing a raw binary firmware image in Ghidra.

Prep work in Binwalk

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.
