Capstone

I play a bit today with this disasm library with BSD license and I should note that it is now virtually unusable
  1. size of libcapstone.so is 6.5Mb and even if you remove arch/Mips, arch/AArch64 and arch/ARM from Makefile size of libcapstone.so is still 3.5Mb. Just to compare - size of libudis86.a on the same machine is only 452Kb
  2. with udis86 you can easy remove tables with mnemonics (for example they are useless in code analyzers) but this is hard to do with capstone - every arch/mapping.c file contains mix of register names, mnemonic tabs and insn_map structures
  3. X86GenDisassemblerTables.inc has size 37Mb ! Authors claim "That is the price to pay for good performance". Perhaps, but 37Mb - it's too much IMHO
  4. It seems also that it is very hard to build a library that will fill cs_x86 structure and does not contain references to xprintf or other CRT functions (for example if you plan to use this library in kernel mode driver)

clang and msbuild integration

chapter 12 of "Inside the Microsoft Build Engine" describes how you can add mingw toolchain to msbuild (visual studio 2010 and newer versions)
So I was very glad to see this patch. But it seems that it does not contains nothing usefull and just don't works !
I wonder if there are some way to integrate clang with msbuild. I missed something ?

crc32 binding for perl

I am tired calculating thousands crc32 hashes of exported functions so I made today binding crc32 for perl
Sample of using:
my $val = crc::my_crc32("GetProcAddress"); # 0xC97C1FFF

or even inside IDA Pro:
use IDA;
use crc;

sub form_ascii
{
  my $addr = shift;
  my $res = '';
  my $c;
  while( $c = Byte($addr) )
  {
    $res .= chr($c);
    $addr++;
  }
  return $res;
}

printf("%X\n", crc::my_crc32(form_ascii(ScreenEA())));

This binding uses swig

exref.pl

a very common problem in static code analysis is finding an exported functions that refers to some desired address. For example KseEngine has 21 references in windows kernel but only 5 of these functions are exported
So I wrote simple perl script for IDA Pro to automate this boring work. Sample of output for KseEngine:
_KseQueryDeviceFlags@12: 74A6C1 addr 74A6E2
_KseQueryDeviceData@20: 74A75B addr 74A77A
_KseQueryDeviceDataList@16: 7A5E74 addr 7A5E95
_KseSetDeviceFlags@16: 7A672D addr 7A6760
_KseUnregisterShim@12: 7A692B addr 7A698B

how to find ntdll!LdrpHashTable

Old article (warning - it is written in French and has eye-breaking font) describes a good idea of loaded modules cross-scaning using LdrpHashTable. But Ivanlef0u did not show how you can find address of LdrpHashTable with static analysis
It seems that this is not easy task - xrefs to LdrpHashTable are not inside exported functions and they called too deeply from nearest export:
  • LdrpResolveDllName
  • LdrpFindLoadedDllByName
  • LdrpInsertDataTableEntry
so ordinary code-flow graph analysis is very difficult. But actually there is more easy way to find address of LdrpHashTable

Inside the Microsoft Build Engine

it seems that book contains huge amount of misprints. for example on page 79:
The syntax when accessing a static property would be as follows:
$({ClassName}::{PropertyName})
o`k, lets check sample of using static properties:
<Message Text="DataTime.Now: $([System.DateTime]::Now)"/>
and below in PropertyFunctions02.proj was used GetPathToSystemFile('msbuild.exe') but output shows path to mspaint.exe

updated perl binding for IDA Pro

I add functions for accessing cmd structure
Now you can do things like this:
#!perl -w
use strict;
use warnings;
use IDA;

my $addr = ScreenEA();
my $href = ua_ana($addr);
my $str = GetDisasm($addr);
if ( defined($href) )
{
  my $iter;
  printf("real: %s, %s:\n", $str, get_mnem);
  foreach $iter ( keys %$href )
  {
    printf("%s: %X\n", $iter, $href->{$iter});
  }
  my $op_idx;
  for ( $op_idx = 0; $op_idx < 6; $op_idx++ )
  {
    my $op = get_op($op_idx);
    last if ( !defined $op );
    printf("operand %d:\n", $op_idx);
    foreach $iter ( keys %$op )

w8.1 preview GetVersionEx - wtf ?

Some simple code:

 OSVERSIONINFOEX osvi;
 ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
 osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);

 if (!::GetVersionExW((LPOSVERSIONINFOW)&osvi))
   return 0;
 printf("Major %d Minor %d\n", osvi.dwMajorVersion, osvi.dwMinorVersion);


produces output
Major 6 Minor 2

O`k, next code sample:
  RTL_OSVERSIONINFOEXW osverEx;
  memset(&osverEx, 0, sizeof(osverEx));
  osverEx.dwOSVersionInfoSize = sizeof(osverEx);
  NTSTATUS res = RtlGetVersion((PRTL_OSVERSIONINFOW)&osverEx);
  if ( NT_SUCCESS(res) )

    printf("Major %d Minor %d\n", osverEx.dwMajorVersion, osverEx.dwMinorVersion);


produces output:
Major 6 Minor 3

openssl-1.0.1e

How to build subj for windows 64bit ? Offical solutions do not work

perl Configure VC-WIN64A
nmake
makefile(609) : fatal error U1002: syntax error : invalid macro invocation '$'
Stop.


O`k, second way:  
ms\do_win64a.bat
nmake -f ms/nt.mak
...
perl crypto\sha\asm\sha256-586.pl tmp32\sha256-586.asm
Pick one target type from
        elf     - Linux, FreeBSD, Solaris x86, etc.
        a.out   - DJGPP, elder OpenBSD, etc.
        coff    - GAS/COFF such as Win32 targets
        win32n  - Windows 95/Windows NT NASM format
        nw-nasm - NetWare NASM format
        macosx  - Mac OS X
NMAKE : fatal error U1077: 'C:\Perl\bin\perl.EXE' : return code '0x1'
Stop.



Wtf, why sha256-586 ? Lets check:  
dir /b crypto\sha\asm\*64.pl
sha1-ia64.pl
sha1-x86_64.pl
sha512-ia64.pl
sha512-x86_64.pl



So source tree does not even contain sha256-x86_64.pl !

building botan with openssl

I`ll describe how to build this cool crypto library with openssl with msvc
It seems that configure.py does not allow you to set additional include & library directories for external packets like openssl/zlib etc
So I used dirty hack
First you just must run configure.py:
python configure.py --cc=msvc --cpu=p4 --enable-asm --with-openssl

Now you can just patch generated Makefile:  
CXX           = cl /MD /IC:\work\src\crypto\openssl-0.9.8y\include
LINK_TO       = advapi32.lib C:\work\src\crypto\openssl-0.9.8y\out32\libeay32.lib user32.lib gdi32.lib

You also need to add gdi32.lib bcs it is used in openssl for functions like DeleteDC. So now you are able build both botan.dll and check.exe:
nmake 
nmake check 
check --test

qmake - wtf ?

I tried today build fresh eql from git and got 16815 errors from linker !
After a comparison with the old version I found that qmake generating different Makefile.Release:

DS -DQT_XML_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THRE
AD_SUPPORT
---
> DEFINES       = -DUNICODE -DWIN32 -DQT_LARGEFILE_SUPPORT -DEQL_LIBRARY -DQT_DLL -DQT_NO_DEBUG -DQT_NO_KEYWORDS -DQT_XML_LIB -D
QT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT


Yes, was used the same version of qmake in both cases
Wtf ?

Update: I found real reason of such behaviour - it`s bcs I forgot add DEFINES     += QT_NAMESPACE=QT to each of eql .pro files. I think this is very annoying and error-prone to fix every .pro file

The main idea is very simple - flair expects .pat file to produce .sig file with signatures. So I just add some logic to my .dcu files loader to generate .pat files in right format

UCXFunctions.idc

It seems that KMDF has possibility to register extension drivers with undocumented (as usually) function WdfRegisterClassLibrary
For example driver Ucx01000.sys (USB host controller extension) contains functions table which I named UCXFUNCTIONS. I wrote simple IDC script to find and add this structure (in addition to ordinary WDFFUNCTIONS) in clients drivers of this extension

srvnet!SrvNetRegisterClient registered clients

It seems that undocumented function srvnet!SrvNetRegisterClient accepts as first argument some structure with handlers. Lets see how it was stored and how we can extract it.

    mov eax, [ebp+srvnet_clnt] ; first argument
    push esi
    movzx esi, word ptr [eax]  ; UNICODE_STRING.Length
    add esi, 84h  ; plus some internal structure size
    push edi
    push 'fbSL'   ; Tag
    push esi      ; NumberOfBytes
    push 200h     ; PoolType
    call ds:__imp__ExAllocatePoolWithTag

  ...
    mov edx, [ebp+srvnet_clnt]
    mov esi, edx
    lea edi, [ebx+4Ch] ; ebx holds allocated memory address

    mov ecx, 8         ; size 4 * 8 = 0x20 bytes
    rep movsd


It seems that input structure srvnet_clnt was copied in offset 0x4c. Prototype of srvnet_clnt: 

struct srvnet_clnt
{
/*  0 */  UNICODE_STRING Name;
/*  8 */  PBYTE RegisterEndpointHandler;
/*  C */  PBYTE DeregisterEndpointHandler;
/* 10 */  PBYTE NegotiateHandler;
/* 14 */  PBYTE ConnectHandler;
/* 18 */  PBYTE ReceiveHandler;
/* 1C */  PBYTE DisconnectHandler;
/* 20 */  PBYTE CredentialHandler;
};


Lets see how this allocated buffer was used next:
    mov edx, _SrvNetDeviceExtension ; some global ptr in srvnet.sys
    cmp dword ptr [edx+0ECh], 4     ; seems like max count check
    mov [ebp+var_1], al
    jge loc_27DAE
    xor eax, eax  ; zero index before cycle
loc_14911:
    movzx ecx, ax
    cmp dword ptr [edx+ecx*4+0DCh], 0 ; check for next free ptr
    jnz loc_149E8
loc_14922:

    lea ecx, [edx+38h]
    cmp ax, 4   
; check for max count
    jz  loc_27E16
    ...
    inc dword ptr [edx+0ECh]  ; inc count of clients
    mov [edx+eax*4+0DCh], ebx ; store current client ptr
loc_149E8:

    inc eax       ; inc current index
    cmp ax, 4     ; again check for max count
    jb  loc_14911 ; go to next cycle
    jmp loc_14922 ; out of cycle

It`s easy to see that all registered clients stored in some internal structure (its address can be found in srvnet!SrvNetDeviceExtension var) in fixed-size (max 4) buffer at offset 0xDC and count of registered clients located at offset 0xEC

bug in Malware and Rootkits Secrets and Solutions

Code from appendix of this book:
 pModuleList=ExAllocatePoolWithTag(NonPagedPool,bufsize,MY_TAG);
 //oops, out of memory...
 if (pModuleList == NULL)
 {
    DbgPrint("\nExamineDriverIrpTables():  [0] Out of memory.\n");
    return;
 }
 nt=ZwQuerySystemInformation(SystemModuleInformation,
                             pModuleList,

 if (nt != STATUS_SUCCESS)
 {
       DbgPrint("\nExamineDriverIrpTables():  [0] Error:

Yeah, memory leak - when authors prepare for memory freeing if call to ZwQuerySystemInformation was unsuccessful ?

crashdmp.sys & CrashdmpCallTable

I noticed in cool presentation "Regaining Control of Your Disk in the Presence of Bootkits" that DriverEntry of crashdmp.sys has strange prototype:

  mov   ebx, [ebp+arg_4] ; DriverEntry(IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath). Do we really write to RegistryPath here ?
  test  ebx, ebx
  cmp   dword ptr [ebx], 1
  jz    short loc_19038
  cmp   dword ptr [ebx+4], 4
  jz    short loc_19038

loc_19038:
  ...
  mov   dword ptr [ebx], 1
  mov   dword ptr [ebx+4], 4
  mov   dword ptr [ebx+8], offset _CrashdmpInitialize@16
  mov   dword ptr [ebx+0Ch], offset _CrashdmpLoadDumpStack@20
  mov   dword ptr [ebx+10h], offset _CrashdmpInitDumpStack@8
  mov   dword ptr [ebx+14h], offset _CrashdmpFreeDumpStack@4
  mov   dword ptr [ebx+18h], offset _CrashdmpDisable@0

[sarcasm mode on]
PC: added decoding of AVX, AVX2, FMA, BMI1, BMI2, F16C, ADX, RDSEED, SMAP, INVPCID, RTM x86 extensions
I just cant believe it, he-he

UI: moved to Qt 4.8.3
I foresee another bloody quest to build pyside in nearest couple of weeks (for example bcs pyside for qt 4.8.3 is still missed in IDA download center)

DWARF: detect and apply Dwarf debug info for ELF and Mach-O files
Why I don`t see mingw here ?

IDS: add IDT files for mfcNN.dll and msvcrNN.dll for VC9/10/11
Oh yeah baby, he-he

IDAPython: wrap obsolete IDA API functions too, so that old scripts continue to work
And there is still no support for functions from include\intel.hpp like x86_scale. Perhaps bcs this functions are not enough "obsolete", he-he
