Adding an Icon

Let’s start by adding an icon. Load up our HelloWorld project from the last tutorial. Click on Project->Resources. This will bring up the Resources window:
Click the Add button and enter in the following info for our icon. Make sure before you do this you copy the icon (supplied in the download) into the Res folder in your HelloWorld project directory. The name of the icon I included is called “clippy.ico”. If you wish to include your own, be my guest, just make sure it’s an .ico file:
Now we’re going to register the icon with our program. The first thing we need is a global variable for the handle to the icon. Open up HelloWorld.inc and add this line:
Now we need to actually load the icon to assign it to our program. We will need to add the appropriate code to the WM_INITDIALOG section:
Now, after you build the project, you will see that the .exe file that RadASM has created has our new icon:

Adding a Menu

RadASM actually makes it quite easy to add a menu, as it has a menu resource editor built-in:
Clicking “Add new”->”Menu” under the Project menu will display the menu resource editor:
This editor let’s us create single button menus, drop down menus and multi-drop down menus (menus within menus). We’ll create a simple menu bar with two options; “help” and “quit”. These will not have drop-down capability. First, enter the information for the first:
Here, we enter the caption (the part that will be displayed) and the name. As soon as you enter these the item will display in the bottom box. At this point you can delete the item by clicking “Delete”, or you can edit it by just highlighting it in the box.
You also have the options to set the attributes of the menu item (for example, greyed out) and changing the item ID. In our case, we’ll leave it at 10001. You can also set up a hot-key for the menu item by clicking the “Shortcut” spinner. Like all other Windows IDEs, you can enter an ampersand (&) before any letter to make it an accelerator (for example, E&xit makes it so you just have to press the ‘x’ key to trigger the menu item.)
Let’s add our second. Click the empty line below “Help” in the bottom box which gives us a new item to modify:
At this point, if you wanted to insert an item between the two, you would simply highlight the first and click “Insert”. This will insert an empty item between the two.
Another thing you may have noticed are the four blue arrow icons. The up and down icons allow you to change the order of the menu items. The left and right one determine if the menu item is a header or a sub item. For example, let’s add a “File” menu, and when you click this, an additional menu drops from it with the option to “Save”. In this case, we would first create the File name ( at the top by highlighting Help” and clicking the “Insert” button):
We would then create the save item going in this menu by clicking the “Help” item and clicking “Insert”, then inserting the data for save:
Now, higlighting the “save” item and clicking the right arrow key makes this item a sub-menu item of the one on top of it, in this case the :File” header:
Now when we run the app, we see a new menu header with a Save option under it:
Note: For the sake of this tutorial, I deleted the “File” and “Save” menu items.
You will also notice, after clicking OK, RadASM has created our new menu in a .mnu file:
Any time you open this file, the menu editor will appear. If you open this file in Notepad, you can see what’s in it:
Now, when we run our program, we see our menu items automatically appear, Of course, they don’t do anything yet:
We need to add the code to handle he menu’s messages. First, the two lines shown need to be added to the HelloWorld.inc file:
Then we need to add the message handlers into the HelloWorld.asm file:
Notice that, because the menu handlers had to go first, the “.if DX==BN_CLICKED” line was changed to “.elseif DX==BN_CLICKED”.
Finally, we need to add a new string so that our menu does something when you click “About”:
Now when we run our program, we can select our new menu items:

Creating Our First Project

Let’s create our first Windows program. Select “New Project” from the File menu. This brings up the New Project Wizard:
The assembler drop down lists all of the various languages we installed at the beginning. In my case, I only have one: Masm.
The project type allows you to designate what type of project we will be making. Setting the different types allows RadASM to pre-make some files for you, along with setting certain settings that go along with your program type. For example, if you select “Dll Project”, files will be created to help set up DLL exports and such. For our first program, let’s keep it set to Win32 App. Type in a name in the Project Name field. I entered “HelloWorld”. The other fields can be left blank. Click “Next”.
Next is the template selection screen:
Templates allow you to pre-populate files with code templates. RadASM comes with several templates for Win32 applications, or you can write your own and save them. The “DialogasMain sets up a project using a dialog as the main screen. The Win32exe sets up a project with a single window but more callback message handlers. For now, select the “DialogApp.tpl” template and click “Next” This will set up  a simple window project.
The next screen is the Files and Folders screen. this screen allows you to choose some files and folders you would like the program wizard to create for you. For example, if programming a Win32 application, we will probably want a resource file (.rc) as well as an include file (.inc). The Bak, Mod and Res options are for creating folders, so if you like to keep all resource objects in a Res folder, keep this highlighted. The Bak folder is a place to store backups of your project. Just leave everything as it is and select “Next”:
Finally, we reach the Make screen. This allows us to change the command line options, debugger, and the options we would like displayed on the “Make” menu drop-down. A lot of this is more advanced, so just leave everything as it is and click “Finish”.
You will see that RadASM has created several files for us already:
Let’s take a look at what files RadASM has created. First, double-click the HelloWorld.Asm file. This opens the code in the main window:
As you can see, RadASM has set up a skeleton app that displays a dialog, and has areas we can enter code for some basic message handlers. Next, let’s look at the HelloWorld.Inc file:
Here we have some basic includes, an ID for the dialog and a dword space set up for the instance handle. Now let’s look at HelloWorld.rc (skipping the .dlg file for a moment):
This just contains an include so we can have our .rc file in a folder (Res). Lastly, double-click the HelloWorld.dlg file. This opens the Dialog Editor:
Notice we have a toolbar along the left-hand side. This is for adding elements to our dialog. This screen is also for changing attributes and IDs of our various dialog controls.
Now let’s run our new program. You can either build the target in steps (ie. assemble, link, run) or you can do everything in one step. These options are on the “Make” menu drop-down. Clicking “Go” assembles, links and runs the program. “Run” can be selected if you are re-running the app (after it has already been built). Also remember, any time you change the resource file you must rebuild it by selecting “Compile Resource”, though clicking “Go” will do this automatically.
Go ahead and select “Go” or click the appropriate toolbar button. If a dialog pops up asking if you want to accept the command, select the check mark “Don’t ask again” and click OK. Now our app’s dialog should appear:
Not a lot to it, though this is only a template. Let’s spice it up a little…

Creating Some Controls

Let’s spiff up our dialog a little by adding some buttons and bitmaps. First we’ll add the buttons. Double-click on the HelloWorld.dlg file to open the dialog editor. Next click on the button tool in the dialog editor toolbar (it says “OK” on it). If for some reason the toolbar is not displayed, click on the little hammer and wrench icon on the main toolbar to display it. Then, click and drag a button in the bottom left-hand corner of the dialog:
RadASM will automatically name this button IDC_BTN. Now we want to change the attributes of this button, so while the button is highlighted, you will see the attributes in the bottom right of the RadASM window:
I have changed the caption (the text in the button) and have changed the button to display multiple lines. You will see the new caption show up in the button:
Now add another button on the right-hand side in the same way, setting it’s attributes to the following:
and the buttons will update in the dialog editor:
Now if you build and run the app, you will see our new dialog. Of course the buttons won’t do anything yet:
Next let’s add some pictures. Like any Windows application, we must load in the bitmaps as resources. Clicking the Resources option in the Project drop-down menu, we will be presented with the resource import screen. To add a new resource, simply click the Add button and fill in the information. When you get to the “file” column, click the three dots and drill to the resource folder and select the appropriate bitmap.
*** You should copy the bitmaps into the Res folder of your project. The bitmaps are available in the download of this tutorial. ***
Notice I named the bitmaps IDB_BITMAP1 and IDB_BITMAP2. We will refer to these IDs later. Now, select the Image tool (the icon with the red “RA” in it in the dialog editor toolbar), then click and drag an image like I have done here:
Now we need to change the attributes of this image, pointing it at our resources we loaded earlier. For the ID number, I entered 105. We will refer to this ID in the HelloWorld.Asm file. I changed the name to match the name we gave our first resource in the resource import screen, IDB_BITMAP1. I added a border, changed the width and height to match the dimensions of the actual bitmap, and changed the type from “Icon” to “Bitmap”:
The image should appear in the dialog editor. Now go ahead and add another exactly as we did the first but this time on the above the Angelina Jolie button, naming this one IDB_BITMAP2 and changing the other attributes to match these:
You should see both images, along with our buttons in the dialog editor now:
Building and running the app shows us the fruits of our labors:
Now we must add the code to handle the events of clicking on the buttons. First, we will add the message handler for the two buttons. Load the HelloWorld.Asm file into the main window. We will make it so clicking on a button will display a message box. I will define the text strings for the message box in the next step:
Notice that eax is compared with the ID we gave the buttons, IDC_BTN1 and IDC_BTN2.
Now we can add the text strings to the top of HelloWorld.Asm:
Finally, we have to add the IDs we created for the buttons in the HelloWorld.Inc file:
Running the app now displays our wonderfully compelling and useful app:

RadASM is a very good IDE (Integrated Development Environment: think Visual Studio) for developing in most programming languages, though assembly language is where it shines. Not only is it one of the few IDEs out there that will work with assembly language, but the author has also put a significant amount of time and effort into it, making it extremely feature rich and robust. Many people use inline assembly in Visual Studio (using __Asm directives) but you really can’t get the level of control in these big-name IDEs as you can in this product. I used WinASM, a very good product, for years, but when I finally tried RadASM, it felt like someone had created it that really knew assembly language, and the hardships that can bring.
In this series of tutorials I will go over installing RadASM, running it, and creating programs in it, as well as some additional plugins and features. In the download for this tutorial (available on the tutorials
page) I have included all of the installation files for RadASM, as well as the Masm SDK, providing everything you need to program in assembly language. So let’s get started.
Please keep in mind that this is not an assembly language nor a Windows programming tutorial. It is assumed that both of these have already been learned. If you are rusty (or a beginner) I highly recommend the Windows assembly tutorials by Iczelion. Fortunately, they are also based on RadASM, so the transition should be very easy.
http://www.woodmann.com/RCE-CD-SITES/Iczelion/index.html

Installation

The first thing we need to do is install Masm onto our computer. Masm is the actual compiler (the same one Visual Studio uses) and has been around a very long time. There is an install.exe file in the Masm32v11r.zip file included in this download. Unzip it and run it- it will automatically install Masm onto your computer. I suggest, in order to eliminate problems in the future, you simply install it into it’s own folder in your root folder on your drive, for example “C:/MASM”.
Now we need to install RadASM itself.
The first file we need is RadASM.zip. This is the main IDE files. Copy these into a new folder. This will now be your root install directory, so you may want to copy this folder in to your Program Files folder, make a shortcut etc.) Next we need to add support for Masm (or TASM, GoASM or nASM). As RadASM is a generic IDE, and works with pretty much any language you can throw at it, we need to give RadASM the specific details about the assembly language we’ll be using.
Open the Assembly.zip file and copy the appropriate folder to the root folder of the RadASM installation. I copied the Masm folder, as that’s the type of assembly I work in (and most others do as well). If you wish to work in one of the other languages, you can copy those as well. We also need to copy the associated .ini file in the root folder as well, in my case Masm.ini. Finally, copy the appropriate .ct and .kwl files into the addins folder in the root of the RadASM folder.
Next, copy the RadASM.chm help file into the Help folder in the RadASM root installation folder. Now, when you click “Help”->”RadASM” in the IDE, this help file will be displayed.
“RadLanguages.zip” contains additional languages (besides English) if you wish to have the IDE in a different language. It defaults to English.
Finally, as you are probably just getting started with assembly language, you can copy the “Demos.zip” and “Games.zip” contents into a Demo folder in the root installation folder. This will give you plenty of examples to look at.

Setting Up the Environment

Now run RadASM and you will see the basic layout:
First things first,  select Options->Programming Languages. Click the “…” button, select the Masm.ini file and hit the “add” button. Masm should now appear in the list of languages. If you have a different assembly type (or want to add additional types) like Tasm or GoASM,  repeat the process for each one. Then click OK. You now have support for that particular language:
Now, you may want to open up any project just to see the color scheme. Here, I loaded the “DragNDrop” project from RadASM root/Masm/Projects/DragDrop. The project file ends with a .rap. You will see the project in our Project Explorer on the right:
Now double-click on the DragDrop.asm file to open it in our code window:
as you can see, the default color scheme leaves a little to be desired. I personally can’t even see the dark blue text, though I am getting old, so what can I say. Let’s change the color scheme to something a little softer on the eyes. Select “Option”->”Color & Keywords”. This brings up the main color selector:
I don’t know about you, but I like to personalize my coding environment. his window allows you to do just that. The method to change colors starts with a theme. There are a couple that come with RadASM and if you look really hard, you can find some additional ones online. But since EVERY option (and I mean EVERY) is changeable, you really won’t need one. I started with the default theme, Dark Night, and modified it from there. If you prefer a lighter background, try one of the other themes. Just select it and click “Load”, the n”Apply” and you will see it pop up. Start with whatever theme is closest to what you like, then you can fine-tune it from there.
To fine-tune it, we go to the Colors and Syntax box below. Here, we choose any type of instruction and select a color for it. You can either select a default color under the Colors group, or you can double-click the type in the Syntax group and select any color you want. For example, if I write a quick comment in the code:
and decide I would instead like it green, I would open the color picker, double-click “Comment” under the Synatx group, and pick a nice green. Clicking Apply will then show me the results:
Because there are so many options that can have their colors changed, a lot of times I will simply look for a color I don’t like in the Syntax group and then change it. Eventually, you will learn what each group type is, or through trial and error will figure it out. After selecting the color I prefer, I now have my own color scheme:
If one of you reading this tutorial would like my exact colors (or want to trade with someone else), you can open the RadASM.ini file provided in this download and copy everything under the “[Colors]” section into the RadASM.ini file in your root folder, replacing what you have with what you copied. Your colors will then match mine exactly.
The last thing I like to do is change the default font. I find the default one a little blocky, so I have included a font designed for assembly language users in mind (I don’t know if this is true, but it sure is a lot better than the default.) It is called Dina, and is in the download with this tutorial. Just unzip the contents and copy them in to the Windows font folder, re-run RadASM, and select “Option”->”Font options”. Now, select the installed Dina font for the first three:
Some other configuration in the Option menu you may want to look at are the following:
  • Languages: Changes the IDE language (if you prefer German, for example)
  • Programming Languages : Adds new templates for additional programming languages.
  • Code Editor Options: Change tab stops, backup policies etc.
  • Dialog Editor Options: For changing the look of dialogs in the Dialog Editor.
  • Menu Accelerators: For adding your own hot-keys.
  • Addin Manager: For adding and deleting addins.

The Toolbar

Depending on which addins you have installed, the addins icons at the right-hand side may be different, though Notepad and Windows Calc will always be the first two icons.
One interesting feature that should be pointed out is the “Tabs” button. This opens the Tabs toolbar:

EditMethod 1 of 3: Get Started

1Type in the person's username. If the username is required, then this is the first step to being able to guess the password. If you don't know the person's username, try to find his username from a variety of other sources, such as the person's username in various social networking sites such as Twitter.


2See if the password has to meet any requirements. See if the password has to be a certain length (typically passwords have to be at least 6 characters long), and if it has to have at least one number or one symbol. If you're not sure, you can try setting up your own account at the site where you're trying to guess the password from, and you'll be told the requirements of the password.
3Ask for a hint. If the password has a "hint" option, then ask for a hint to guide you in guessing the password. The hint question can be something like, "What is your mother's maiden name?" or "What is the name of your first pet?" These questions can help narrow down your guessing; though you may not know the name of the person's first pet, you can guess from a number of pet names. Or, if you want to be extra sneaky, you can try to bring up first pets in a conversation with that person.
The hint can narrow down your search quite a bit if you know some personal information about that person. For example, if the question is, "Where were you born?" you may already know the person's birth state -- or even his birth city.
EditMethod 2 of 3: Use Password Tricks
1Guess the most common passwords. At the end of every year, a list of the 25 most common passwords is released. These passwords are the easiest to guess and thus the most commonly hacked. Though you should avoid picking any of these passwords for yourself, try guessing from this list of passwords:[1]
password
123456
12345678
abc123
qwerty
monkey
letmein
dragon
111111
baseball
iloveyou
trustno1
1234567
sunshine
master
123123
welcome
shadow
ashley
football
jesus
michael
ninja
mustang
password1
2Use some common password tricks. Other than guessing the most obvious passwords, there are a few tricks that are used by professional password guessers. They know, for example, that there's at least a 50% chance that a user's password will have one or more vowels. Here are a few other tricks that you should know:[2]
If the password has a number in it, it will be usually be a 1 or a 2 and it will be at the end of the password.
If there's a capital letter in the password, it will usually be at the beginning -- often followed by a vowel.
3Know that gender can also help predict a person's password. Women tend to use personal names in their passwords, while men prefer to use their hobbies or interests instead. For example, a woman can place her husband or best friend's name in a password, while men can have a password related to his favorite sports team, favorite sport, or favorite athlete.
Men may also use their favorite athlete's jersey number for the numbers in their password.
EditMethod 3 of 3: Guess Passwords Related to the Person
1Guess personal names. Many people have personal names in their passwords. Most people wouldn't put their own names in a password, but you could try those anyway. Here are some other names to try when you're guessing a password:
The name of the person's significant other or spouse
The names of the person's siblings
The name of the person's current or favorite pet
The name of the person's (especially a male's) favorite athlete
The person's childhood nickname or current nickname
2Guess the person's hobbies and interests. You can also guess a password by thinking of the person's hobbies or interests. Here are some tricks to try:
Try combining a man's favorite athlete with his favorite sport. For example: "Tigergolf" or "Kobebball."
Guess the name of a woman's favorite TV show, or the name of a favorite character on that show.
Guess the name of a person's favorite athletic hobby. If the person loves to swim, try "Swimmer" with some numbers after it.
3Guess important numbers. Many people use numbers in their password, indicating a date or a lucky number. Some people even make their whole password consist of numbers. You can try these numbers on their own, or add them to the end of one of the words that you guessed. Here are some ways to guess a person's password based on numbers:
Guess the person's birthday. For example, if the person's birthday is 12/18/75, type in "121875" or "12181975."
Try the person's street address. The person's street address, such as 955, could be a part of the password.
Try the person's lucky number. If the person has been vocal about what his lucky number is, try it.
If the person played a sport, try his jersey number as part of the password.
Try a part of the person's phone number.
Try the person's graduating class from college or high school.
4Guess the person's favorite things. You can also guess the person's password by guessing from a number of the person's favorite things. Here are a few favorite things to try:
The person's favorite TV show.
The person's favorite movie.
The person's favorite food.
The person's favorite book.

How to hack any Facebook account in under a minute, by sending just one SMS


If you're new here, you may want to subscribe to the RSS feed, like us on Facebook, or sign-up for the free email newsletter which contains computer security advice, news, hints and tips. Thanks for visiting!
Facebook mobile phoneA UK-based security researcher going by the name of “fin1te” has earned himself $20,000 after uncovering a way to hack into any account on Facebook, just by sending a mobile phone text message.
This should – obviously – have been impossible, but due to a weakness in Facebook’s tangled nest of millions and millions of lines in code, potentially hundreds of millions of accounts were vulnerable to hijacking through the simple technique.
Fin1te (real name Jack Whitten) has documented how the hack works on his blog.
The first thing to do is send the letter “F” in an SMS message to Facebook, as though you were legitimately registering your mobile phone with the social network. In the UK, the SMS shortcode for Facebook is 32665.
Send an SMS to Facebook
Facebook responds, via SMS, with an eight character confirmation code.
The normal sequence of events would be to enter that confirmation code into a Facebook form, and go on your merry way…
Facebook mobile activation form
But fin1te discovered that a vulnerability existed on that form, that could be exploited to use the confirmation code he had been sent by Facebook via SMS with *anyone* else’s account.
What fin1te had uncovered was that one of the elements of the mobile activation form contained, as a parameter, the user’s profile ID. That’s the unique number associated with your intended target’s account.
Profile ID parameter inside form
Change the profile ID that is sent by that form to Facebook, and the social network might be duped into thinking you are someone else linking a mobile phone to their account.
Therefore, the first step needed to hijack someone’s account in this way requires your victim’s unique Facebook profile ID.
If you don’t know what someone’s numeric profile ID is, you can always look it up using freely-available tools – they aren’t supposed to be a secret.
Find a Facebook profile ID
Sure enough, fin1te was able to replace the profile ID parameter sent by his browser to Facebook with the unique number of the account he wanted to access…
Facebook hack data
.. and within seconds his his mobile phone was sent an SMS confirming that he had successfully connected the device to the account.
Facebook confirmation SMS
Success. A Facebook account now has a third-party’s mobile phone number associated with it. Without any need for malware or phishing. All that was done was to send an SMS text message.
The final stage of the account hijacking is straightforward. Facebook allows you to log into its system using your mobile number rather than an email address if you want, so at login you enter the mobile phone number you have associated with your victim’s account, and request a password reset via SMS.
Reset code
Sure enough, fin1te discovered that Facebook duly sent him the password reset code for the account – meaning he could change the account’s password, and lock out its legitimate user.
This is an incredibly simple but powerful way to take over anybody’s Facebook account.
The good news is that fin1te disclosed the vulnerability responsibly to Facebook, rather than exploited it for malicious intentions or sold it to other parties. Facebook has fixed the problem so others can no longer take advantage of this serious security hole. For his troubles, Facebook awarded fin1te a hefty $20,000 worth of bug bounty and fixed the vulnerability.
But there’s no doubt that on the underground market, perhaps sold to cybercriminals or intelligence agencies, fin1te’s discovery could have earned him even more money.
Who knows what other serious security vulnerabilities may lay inside Facebook that haven’t been responsibly reported to the company’s security team?
If you are on Facebook, and want to be kept up to date on the latest privacy and security risks threatening users, be sure to Like the “Graham Cluley Security News” Facebook page .
