[序言]
在2024年08月左右, hex-rays官方不测的泄露了全版本(Win Mac Linux)全功能的IDA Pro 9.0, 让整个逆向社区打一剂鸡血针, 随后大量的打包版本出现比如: IDA Pro 9.0 Beta官方泄露版, IDA Pro 9.0 RC1发行版. 总之版本混乱, 但随着时间的推移, 大概快2个多月左右, 官方突然把RC1版本直接转换为了正式版. 因此就有目前最纯净最干净的版本: 2024 IDA Pro 9.0.240925 v2官方正式版.
[Windows平台运行]
首先,必要下载2024 IDA Pro 9.0.240925 v2官方正式版 的安装包, 可以从下面的链接下载:
* 磁力链接:magnet:?xt=urn:btih:b2e16894b6c40774283560fe292e5d4bc68c512f&dn=IDA%209.0.240925%20v2
* 下载完成后, 还必要另外下载 keygen2.py 文件(已附上源码, 请下载生存)
打开keygen2.py文件, 并修改其源码. 详细修改如下:
* 替换 elf: "name": "elf" -> 任意替换一个名字
* 替换 "elv@ven: "email": "elv@ven" -> 任意替换一个邮箱
* 修正授权文件发行时间: "issued_on": "2024-08-10 00:00:00"
修改完成后, 将修改好的keygen2.py文件复制到由ida-pro_90_x64win.exe生成的安装目次(IDA Professional 9.0), 并运行. 乐成的话, 会出现以下三个文件:
* ida.dll.patched
* ida32.dll.patched
* idapro.hexlic
这三个文件就是破解好的文件.
最后, 我们必要备份原版的 ida.dll 和 ida32.dll 文件, 并将 ida.dll.patched 和 ida32.dll.patched 文件重命名为 ida.dll 和 ida32.dll. 这样一来, IDA Pro 9.0就能完美运行了.
[注意]
* 必要有肯定的Python动手本领.
* 这个教程适合具有中等以上编程履历的用户.
[总结]
虽然上面给出的是Windows平台的操作步调, 但是其他平台Mac, Linux的处理方式差不多一样的, 大家可以自行研究.
