If you ever wanted to place an image file into the executable or store any resources in it, this post will be able to help you.  If you have previously read Builder & Stub | How to create your own builder and stub in C (using Resource), you will be able to understand this post easily.  We are using the similar method by placing the image in the resource data.  In this post, i am creating an application that extracts the image that has been placed in the resource data and place it in a file and execute the file. 

A man went to a palmist to learn his fortune.  The palm reader studied his hand for a long time and said, "For the next yen years, you will have a very bad time."

"Then what will happen after that?" asked the man.

The palmist looked at his hand again and said, "After that, you will get used to it."

A German, looking for directions in Paris, pulls up to a bus stop where two Americans are waiting.

"Entschuldigung, sprechen Sie Deutsch?" he asks.  The two Americans just stare at him.  "Parlez-vous français?" he says.

The two continue to stare, so the German tries again: "Parlate italiano?" No response.  "¿Hablan ustedes español?"  Still nothing.  Frustrated, the German guy drives off.

The first American says, "You know, we should learn a foreign language."

"Why?" asks the other.

"He knew four languages, and it didn't do him any good."

Did you ever have a need to store strings in a string arrays and not waste spaces?  In this post i will be explaining some of the ways that you can save yourself from destroying the RAM!

Ever wondered how the Portable Executable (PE) file format works?  Read up on what Matt Pietrek has to say about PE files.  This article may be time consuming but if you are into researching the PE file format it is worthwhile.  Some of the things covered include 

When I am down and, oh my soul, so weary;
When troubles come and my heart burdened be;
Then, I am still and wait here in the silence,
Until you come and sit awhile with me.

You raise me up, so I can stand on mountains;
You raise me up, to walk on stormy seas;
I am strong, when I am on your shoulders;
You raise me up: To more than I can be.

You raise me up, so I can stand on mountains;
You raise me up, to walk on stormy seas;
I am strong, when I am on your shoulders;
You raise me up: To more than I can be.

There is no life - no life without its hunger;
Each restless heart beats so imperfectly;
But when you come and I am filled with wonder,
Sometimes, I think I glimpse eternity.

You raise me up, so I can stand on mountains;
You raise me up, to walk on stormy seas;
I am strong, when I am on your shoulders;
You raise me up: To more than I can be.

You raise me up, so I can stand on mountains;
You raise me up, to walk on stormy seas;
I am strong, when I am on your shoulders;
You raise me up: To more than I can be.?

As i have already created a similar post which creates your own builder using the File I/O (Input/Output) operation, some have came across a problem where they need their stub application to be placed and ran in memory instead of normal execution.  In order to counter this problem, the solution that can come into mind is to use the resource data in the file.  Even if your file is ran in the memory, the resource data is also loaded with it.  Be aware that the terms used may confuse you so read the synonym section.  Take a look at the concept below.

If you are looking to build it using Resource, look here.

This question is often seen in one of the forum that i hang around.  Although the programming language is different, the idea and concept is one.  I have already prepared a source code for this project but i will explain a little or less about how it works.  Understand that the term stub i am using refers to the application that is going to read a message that has been injected from an application called builder.  Be aware that the term injected also refers to implanted or appended.  In this article, i will be showing the concept on how a builder and stub works, what will you need before coding it and your preparations as well as pseudocode to ease understanding of the concept.  Apart from that you can download the project in case you are not sure what to do with the source code given due to certain complexity.

As some of you may realize, i am placing "Read the rest of this entry" links over my posts.  I believe that this way allows readers to browse posts easier instead of reading the entire article.  Let me know what you think!

Generally when i started blogging i did not know about the "Insert More tag" until today.  I was looking for theme's that has it by default and i also ended up googling CSS codes for it to customize and stuff but oh well.  If you are having the same problem, click on the link above!

A parity bit is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code.

There are two variants of parity bits: even parity bit and odd parity bit. When using even parity, the parity bit is set to 1 if the number of ones in a given set of bits (not including the parity bit) is odd, making the entire set of bits (including the parity bit) even. When using odd parity, the parity bit is set to 1 if the number of ones in a given set of bits (not including the parity bit) is even, keeping the entire set of bits (including the parity bit) odd. In other words, an even parity bit will be set to "1" if the number of 1's + 1 is even, and an odd parity bit will be set to "1" if the number of 1's +1 is odd.

Even parity is a special case of a cyclic redundancy check (CRC), where the 1-bit CRC is generated by the polynomial x+1.

If the parity bit is present but not used, it may be referred to as mark parity (when the parity bit is always 1) or space parity (the bit is always 0).

This is our world now. The world of the electron and the switch; the beauty of the baud. We exist without nationality, skin color, or religious bias. You wage wars, murder, cheat, lie to us and try to make us believe it's for our own good, yet we're the criminals. Yes, I am a criminal. My crime is that of curiosity. I am a hacker, and this is my manifesto. You may stop me, but you can't stop us all.

.

What do you think of the term "hacker"?  Do you think of crime, danger or intrusion when you hear it?  Or maybe security, programming and computer analysis.  Do you call yourself a hacker because you know how to make malicious applications or use applications that have been programmed by professionals to do your malicious tasks?  I personally believe that a hacker is someone that has an expertise in the computer system, finding exploits and has the ability to find holes on system and mend it.  Do not believe in what i said, but let's hear what do you think of the word "hacker".

Ever wanted to recover files that has been deleted from the Recycle Bin?  Do you know that what has been so called deleted from the Recycle Bin has merely been marked as "deleted" and not actually entirely removed from the hard drive.  You might be confused with the word delete, rubbish bin, shift+delete button and what not.  Let us first look into the context of how the entire cycle works below.  Jump straight to "Tools to recover deleted files" to download.

The Windows NT and Windows 2000 Resource Kits come with a number of command-line tools that help you administer your Windows NT/2K systems. Over time, I've grown a collection of similar tools, including some not included in the Resource Kits. What sets these tools apart is that they all allow you to manage remote systems as well as the local one. The first tool in the suite was PsList, a tool that lets you view detailed information about processes, and the suite is continually growing. The "Ps" prefix in PsList relates to the fact that the standard UNIX process listing command-line tool is named "ps", so I've adopted this prefix for all the tools in order to tie them together into a suite of tools named PsTools.

Today is the first fun of 2011! Although i missed some karaoke and clubbing, i had a trip with my mates. We spent the whole day in a small town by the countryside. Being able to eat food aside the ordinary ones we have back in our city, it was totally awesome! We also went to historical places and took funny pictures.

Alright, i'm out of ideas on what to write. Going back to computing, i'm coming out with an application that is used to provide cryptography algorithm in VB .NET with association of C in dynamic-link library. Be sure to look forward to it and suggest some of the cryptography algorithms that you would expect to find from the application.

Ever heard of the word Modus operandi or MO?  Modus operandi (MO) is a Latin term that means "a method of operating." It refers to the behaviors that are committed by a criminal for the purpose of successfully completing an offense. A criminal's MO reflects how they committed their crimes. It is separate from their motives, which have to do with why they commit their crimes.

Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), and a utility for comparing scan results (Ndiff).

Nmap was named “Security Product of the Year” by Linux Journal, Info World, LinuxQuestions.Org, and Codetalker Digest. It was even featured in eight movies, including The Matrix Reloaded, Die Hard 4, and The Bourne Ultimatum.

Nmap is ...

• Flexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.


• Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines.


• Portable: Most operating systems are supported, including Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.


• Easy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Both traditional command line and graphical (GUI) versions are available to suit your preference. Binaries are available for those who do not wish to compile Nmap from source.


• Free: The primary goals of the Nmap Project is to help make the Internet a little more secure and to provide administrators/auditors/hackers with an advanced tool for exploring their networks. Nmap is available for free download, and also comes with full source code that you may modify and redistribute under the terms of the license.


• Well Documented: Significant effort has been put into comprehensive and up-to-date man pages, whitepapers, tutorials, and even a whole book! Find them in multiple languages here.


• Supported: While Nmap comes with no warranty, it is well supported by a vibrant community of developers and users. Most of this interaction occurs on the Nmap mailing lists. Most bug reports and questions should be sent to the nmap-dev list, but only after you read the guidelines. We recommend that all users subscribe to the low-traffic nmap-hackers announcement list. You can also find Nmap on Facebook and Twitter. For real-time chat, join the #nmap channel on Freenode or EFNet.


• Acclaimed: Nmap has won numerous awards, including "Information Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has been featured in hundreds of magazine articles, several movies, dozens of books, and one comic book series. Visit the press page for further details.


• Popular: Thousands of people download Nmap every day, and it is included with many operating systems (Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD, etc). It is among the top ten (out of 30,000) programs at the Freshmeat.Net repository. This is important because it lends Nmap its vibrant development and user support communities.

Those of you that think of yourself as a hacker, do you know what does a network packet look like?  Have you ever read network packets in your life, do you know how they work?  Take a look in the TCP packet below and try to figure out what the packet is doing as well as getting the source ip address and port of the sender.

[code]
00 1c f0 39 8e 45 00 1c  f0 8a a1 71 08 00 45 00
00 34 06 6e 40 00 80 06  9a 0e c0 a8 01 02 45 a2
52 fb c0 a7 00 50 a1 f6  7c bb 00 00 00 00 80 02
20 00 15 25 00 00 02 04  05 b4 01 03 03 02 01 01
04 02
[/code]

Tips: Think of the packet as an Ethernet frame.

There was once where i was stucked looking for a site which contains all the encryption and decryption process for most of the common available encryption algorithm.  I recently found it from a tutorial on HackForums and thought of sharing it here as well as keeping it close to myself.  Although it is common on HackForums i don't hang around there much though so i kind of forgot the site.

In computer programming, DLL injection is a technique used to run code within the address space of another process by forcing it to load a dynamic-link library.^[1] DLL injection is often used by third-party developers to influence the behavior of a program in a way its authors did not anticipate or intend.^[1][2][3] For example, the injected code could trap system function calls,^[4][5] or read the contents of password textboxes, which cannot be done the usual way.^[6]

Approaches on Microsoft Windows

• DLLs listed under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs will be loaded into every process that links to User32.dll as that DLL attaches itself to the process.^[5][7][8][9]


• Process manipulation functions such as CreateRemoteThread can be used to inject a DLL into a program after it has started.^{[5][6][10][11][12][13]}
  
  
  
  1. Get a handle to the target process. This can be done by spawning the process^[14][15] or by keying off something created by that process that is known to exist – for instance, a window with a predictable title,^[16] or by obtaining a list of running processes^[17] and scanning for the target executable's filename.^[18]
  
  
  2. Allocate some memory in the target process,^[19] and the name of the DLL to be injected is written to it.^[10][20]

     This step can be skipped if a suitable DLL name is already available in the target process. For example, if a process links to ‘User32.dll’, ‘GDI32.dll’, ‘Kernel32.dll’ or any other library whose name ends in ‘32.dll’, it would be possible to load a library named ‘32.dll’. This technique has in the past been demonstrated to be effective against a method of guarding processes against DLL injection.^[21]

  
  
  3. Create a new thread in the target process^[22] with the thread's start address set to be the address of LoadLibrary and the argument set to the address of the string just uploaded into the target.^[10][23]

     Instead of writing the name of a DLL-to-load to the target and starting the new thread at LoadLibrary, one can write the code-to-be-executed to the target and start the thread at that code.^[6]

  
  
  4. The operating system will now call DllMain in the injected DLL.^[10][24]
  
  
  
  

  Note that without precautions, this approach can be detected by the target process due to the DLL_THREAD_ATTACH notifications sent to every loaded module as a thread starts.^[24]



• Windows hooking calls such as SetWindowsHookEx.^{[2][5][6][25][26][27]}


• Use the debugging functions to pause all threads, and then hijack an existing thread in the application to execute injected code, that in turn could load a DLL.^[4][28][29]

So what did you get for Christmas?  I'm sure everyone must have enjoyed theirs!  Here's a quick note on what i intend to do for the next few hours, days,  ...years.

I will be releasing released a source code that i have compiled for some time now which helps retrieve passwords that has lost for programs such as WLM, Firefox, No-IP and DynDNS.  The source codes are coded in C language so basically it's just a header.  In order to use it you'll just call the function like RetrieveWLM("recovery.txt");.  Look forward to lots more of source codes that will be released from my personal code vault.

This source code below converts a text file with binaries into a text file with hexadecimals. Imagine we have a file of binaries called "hello.bin", we are going to convert it into hexadecimals and write it into a file called "hello.com".

hello.bin

[code]
10110100 00001001
10111010 00001001 00000001
11001101 00100001
11001101 00100000
01101000 01100101 01101100 01101100 01101111 00100100
[/code]

Concept (in terms of ASM)

[code]
mov ah,09
mov dx,0109
int 21
int 20
db "hello$"
[/code]

hello.com

[code]
B4 09 BA 09 01 CD 21 CD 20 68 65 6C 6C 6F 24
[/code]

where you can see how the binaries, hexadecimals and ASM are linked.

[code]
10110100 = B4 = mov ah
00001001 = 09 = 09
[/code]

What "hello.com" does when ran is it prints the word "hello" and exits. Generally this code is a converter but it has given me a further insight of what assembly would look like and how the machine language works now. The source code is as below and it is done in C language (but you would need to write the filename as .cpp instead of .c since the program was not programmed according the C proper structure whereby it should be defining variables before statements).

Source code

[code]
#include <stdio.h>
#include <stdlib.h>

void help(char* fname) {
printf(
"Code programs in binary - by Jakash3\n"
"Usage: %s outfile infile"
"Notes:\n"
" infile = Text file containing ascii 1's and 0's.\n"
" 8 bits per byte, all other characters\n"
" and whitespace ignored.\n"
" outfile = Name of program to create and write to.\n",
fname
);
exit(1);
}

int main(int argc, char** argv) {
if (argc!=3) help(argv[0]);
FILE *dst, *src;
dst = fopen(argv[1],"wb");
if (!dst) { printf("Could not create or truncate %s\nQuitting...",argv[1]); return 1;}
src = fopen(argv[2],"r");
if (!src) { printf("Could not open %s\nQuitting...",argv[2]); return 1;}
char c, byte=0;
int i=0, count=0;
while (!feof(src)) {
if (i==8) { fwrite(&byte,1,1,dst); byte=0; i=0; count++; }
fread(&c,1,1,src);
switch (c) {
case '1':
byte |= ((c=='1') << (7-i));
case '0':
i++;
}
}
fclose(src);
if (!fclose(dst))
printf("Wrote %d bytes to %s\n",count,argv[1]);
return 0;
}
[/code]

Are you a programmer that loves to design malicious application?  Do you find malicious applications that you have made are easily detected by anti-virus software (oh come on, Fully Un-detectable (FUD) isn't going to last long)?  Do you know the difference of user and kernel space?  Ever wanted to be able to stay on the same level as the anti-virus as well as getting rid of it?

Take yourself into a whole new level by learning how to develop a rootkit!

Full details on types of threats can be read here.

• An interception means that some unauthorized party has gained access to an asset. The outside party can be a person, a program, or a computing system. Examples of this type of failure are illicit copying of program or data files, or wiretapping to obtain data in a network. Although a loss may be discovered fairly quickly, a silent interceptor may leave no traces by which the interception can be readily detected.


• In an interruption, an asset of the system becomes lost, unavailable, or unusable. An example is malicious destruction of a hardware device, erasure of a program or data file, or malfunction of an operating system file manager so that it cannot find a particular disk file.


• If an unauthorized party not only accesses but tampers with an asset, the threat is a modification. For example, someone might change the values in a database, alter a program so that it performs an additional computation, or modify data being transmitted electronically. It is even possible to modify hardware. Some cases of modification can be detected with simple measures, but other, more subtle, changes may be almost impossible to detect.


• Finally, an unauthorized party might create a fabrication of counterfeit objects on a computing system. The intruder may insert spurious transactions to a network communication system or add records to an existing database. Sometimes these additions can be detected as forgeries, but if skillfully done, they are virtually indistinguishable from the real thing.

Have you ever wanted to create your own program that communicates with the MSN instant messaging tool?  This is possible by learning how MSN works in the eyes of a programmer!  Take a look at http://www.hypothetic.org.

Detours is a library for instrumenting arbitrary Win32 functions on x86, x64, and IA64 machines. Detours intercepts Win32 functions by rewriting the in-memory code for target functions. The Detours package also contains utilities to attach arbitrary dynamic-link libraries (DLLs) and data segments (called payloads) to any Win32 binary.

Today i decided to try out TeamViewer via iPod.  I ended up finding fascinating adventures with it.  Below are some of the unthinkable ideas i had.



Cookie 1

Imagine that you are sitting in Starbucks and your friend urgently needs a document from you that you have at home which is half an hour away.  No worries for TeamViewer is here; with your iPod or iPhone in your hand, connect to Starbucks wireless connection and run TeamViewer's app (Download).  Connect to TeamViewer software which you have run earlier at home (either Mac, Linux or Windows) and open up your e-mail service and send it to your friend! Voila, problem solved!



Cookie 2

I was so lazy lying on my bed and i wanted to see what is going on on my laptop.  Maybe some friend of mine dropped me a message at Windows Live Messenger / aMSN.  Luckily i had my iPod with me, i simply connected to my home network and launched TeamViewer and connect to my Ubuntu.  My friend Esther dropped me a message so i decided to let her know how great this application was and i decided to communicate this way (it was a new experience) although there is a lot of messaging tool that i know of.  I though of checking what's up with my virtual machine that i have left running and i found nothing much so i decided to shut it down to save processes.  Oh well, finally nothing much to do i just press the "Shut Down..." menu option.  Let's get back to Fruit Ninja!

Wao, if you have an iPhone and you need to do anything anywhere... it's even greater!  Do you know what i thought of... Imagine i'm on the transit while rushing to university which i left my computer on with my current project (programming some silly software again).  I can simply remotely connect to it with TeamViewer and continue debug or turn it off otherwise.  This is one of the most exciting feature i could think off: programming remotely!!

First time playing with apple product as well as first time cracking it via simple guidelines

Well, enjoy if you ever used this guide =) For the time being i'll enjoy my iPod!

What a stupid mistake i made... i accidentally moved my mounted image from my virtualbox to the trash without releasing it first.. i thought of creating a new name and a fake file so that i could release it this way but it appears that the virtualbox does not allow me to do so.

Searching around a few minute on the internet gave me the answer here - http://forums.virtualbox.org/viewtopic.php?f=8&t=26338 Luckily i found the solution (although it isn't something big i found out it's disturbing to have something you don't like to appear so i had to get rid of it).
All in a days work... now i have to continue figuring out how to execute Warcraft III under VirtualBox as well as allowing USB to work in it. (sort of just moved from virtualbox-ose)

For those that are interested in contacting the windows registry via C, here's a list of WinAPI functions that you need to know.

There was a small phonebook code challenge to build the shortest at LeetCoders. Here's a little of what i did for fun. Functions include add contact, remove contact, search contact and display contacts.

[code]
#include <stdio.h>

#define PHONEBOOK_SIZE 512

#include <windows.h>
#include <stdio.h>

#define MUTEX_NAME "mutex name here, anyname"
int main()
{
HANDLE hMutex = OpenMutex(MUTEX_ALL_ACCESS, FALSE, MUTEX_NAME);
if(hMutex == NULL)
{
// no duplicate instances found
hMutex = CreateMutex(NULL, FALSE, MUTEX_NAME);

As you can see, there's OpenMuteX and CreateMuteX function that has been used.  To briefly explain this, OpenMuteX opens a handle to check whether a mutex has been created.  If it returns the value NULL, it means that no mutex of the current string has been created.  So when it is NULL, CreateMuteX is called to create the mutex with the string MUTEX_NAME that has been defined.  Leave a feedback if you feel that there's lack of information.

[code]
#include <windows.h>

int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
HDC hDC = CreateDC(TEXT("DISPLAY"), NULL, NULL, NULL);
POINT pCurPos;
RECT rRect;
HBRUSH hBrush = (HBRUSH)(CreateSolidBrush(RGB(0, 0, 0)));
int iConst = 1;

for( ; ; Sleep(1000))
{
if (GetAsyncKeyState(VK_ESCAPE) != 0)
break;

iConst += 3;
GetCursorPos(&pCurPos);
rRect.left = pCurPos.x - iConst;
rRect.top = pCurPos.y - iConst;
rRect.right = pCurPos.x + iConst;
rRect.bottom = pCurPos.y + iConst;
FillRect(hDC, &rRect, hBrush);
}

DeleteDC(hDC);
return EXIT_SUCCESS;
}

I'm not sure where i got this a year ago but generally this code create a black pixel on your desktop. It will terminate only if you press ESCAPE which is detected by GetAsyncKeyState.

Ever wanted a portable caesar cipher and decipher at one go? At the end of this post you will find the binary as well as the source code (built in C) for the application. Below is an image of the application testing on "abcdefgh" text.  At [+13] you can see that it is equivalent to ROT13 cipher.  For those that are familiar with command line, use application.exe "text here".
