With all the stories in the news on an almost daily basis about hacking, digital security has become one of the most crucial factors in our lives. Most people do their banking online, they use PayPal, they use email and these, plus any other service or website you use with personal information, are open to being hacked. To put it very simply, a hacker is a person who can gain access to a computer system or network and exploit it to steal information, steal financial details, send a virus down to it and do all sorts of other damage.
This book is designed to help you develop the methods you need to keep those hackers away from your system. And, to do that, you must learn to think like a hacker! Skip to content. The Hacker s Guide to Python.
What is Python? Python is considered an open source language, which means that you can download it from the python. If you are migrating from another programming language, you will be able to easily learn Python thanks to its easy readability. Most of the commands use typical English statements which will allow you to immediately understand their purpose even if it is the first time that you have encountered this language.
Python codes are also so much shorter and simpler compared to other high-level languages such as Java, and comes with a library and features that are already built-in, as well as access to third-party modules and libraries.
Its robust integrated libraries and the availability of resources that are compiled by other users make it one of the favorite programming languages of hackers. If you are a first-time programmer, you will find Python to be relatively easy to learn, thanks to its simpler codes and syntax. You will also be able to run your codes on different types of devices and operating systems, such as Android, Windows, Linux, and Mac OS X. If you are interested in jumping right into hacking, you will definitely have endless fun discovering what you can manipulate with your own programs — Python does not only allow you to exploit and manipulate laptops, smartphones, and desktops, but also allow you to run your programs on microcontrollers that are found in toys, remote controls, appliances, and virtually any device that has a computer in it.
Some Windows users, particularly HP computer owners, may also have it installed in their computers. However, if you need a fresh install of the package, you can download it from www. Normally, you would want to get the latest version, which is 3. While Python 3 may be the future of this programming language, certain factors such as compatibility with your computer or using third party services may make you download Python 2 instead.
Windows Installation After you have downloaded the installation package from the Linux website, decompress it and run the. You should be able to get pip, documentation, and IDLE when you go with the standard installation. Note: See to it that you have checked this option: If you want to change the location for your installation, simply click on and then hit Next. If you have installed Python in the correct path, go to: You can also run Python from the command prompt if you have correctly set the PATH variable upon installation.
If you are running Python for the first time in Windows, type cmd in the Run dialog box click on Start button to locate this command. Hit Enter and then provide your user password in order to proceed. Interacting with the Python Language Now that you have installed Python, the next thing that you need to do is to learn how you can use it to explore features or to test a code.
You can use Python using the script mode if you want to see how entire files or applications are interpreted. Right after that, Python will display your requested text on the following line. What will happen if you did something wrong with your command?
An IDE is an application that will provide you all the tools that you need to develop a software. Usually, these tools are a text editor that will help you tweak the source code that you are working on, a debugger, and a set of tools for build automation which you can use through a GUI graphical user interface. IDEs will also allow you to use integration with version control libraries that you can source from third parties, which means that you can pull up codes that are created by others and then mix and match them with your own code to get the results that you want.
You can get your preferred IDE from a third-party source, such as educational sites for programming languages, or from the developers of the language themselves. The IDLE tool that comes with your installation package serves as a platform where you can efficiently key in your codes and interact with Python.
You can easily pull up IDLE by clicking on its icon on your desktop, the Start Menu or locating it on the install folder. IDLE allows you to use these features: The Python shell window which allows you to make use of color-coded code input and output and get error messages if you input a wrong statement. A debugger that comes with stepping, local and global namespace viewing, and persistent breakpoints Browsers and configuration A text editor that allows you to use multiple windows, colorizing for Python, auto- completion, undo, and other features Using IDLE will allow you to use two windows the Shell and the Editor which you can use simultaneously.
You can also have output windows that have a different context menu and title. The menus that you can use in IDLE will change depending on the window that you have selected. The options that belong to each menu are straightforward, which means that you will not have a hard time understanding what each of them do even if you are new to programming. Here are the menus and the window that they are associated with.
File for Editor and Shell windows This menu contains the following options: 1. New 2. Open 3. Recent Files 4. Class Browser 6. Path Browser 7. Save 8. Save As 9. Save Copy As Print Window Close Exit Edit for Editor and Shell This menu contains the following options: 1.
Undo 2. Redo 3. Cut 4. Copy 5. Paste 6. Select All 7. Find 8. Find Again 9. Find Selection Find in Files Replace Go to Line Show Completions Expand Word Show Call Tip Indent Region 2. Comment Out Region 4. Uncomment Region 5. Tabify Region 6. Untabify Region 7. Toggle Tabs 8.
New Indent Width 9. Format Paragraph Strip Trailing Whitespace Run Editor window 1. Python Shell 2. Check Module 3. Debugger 3. Stack Viewer 4. Configure IDLE 2. Code Context available only in Editor Windows 1. Zoom Height Help 1. IDLE Help 3. Python Docs 4. There is no real guideline in choosing where you should type out and save your codes — as long as the editor that you are using helps you code comfortably and comes with syntax highlighting which will help you visualize your code, then you will be able to achieve your hacking goals and create the code that you want to use in the future.
Here are other editors and their features that you might want to check out: PyCharm Educational Edition If you want to focus on learning Python instead of concentrating on how you should be navigating your windows, then this is the editor for you. You can pull up existing codes in the editor to learn how certain programs are written, or learn using the tutorial that comes with it. You can download this free editor from www. Sublime Text Sublime Text allows you to use a package manager, which essentially works for any person that is used to typing in word processors.
It also comes with features such as code folding, which hides lines of codes that you are not working on. Take note that this is not a free software, but it does come with a trial period that does not have a time limit. VIM This free software will allow you to do lots of customizing, which is great if you are an experienced programmer that wants to work using settings that you are most comfortable with. Another plus factor to this software is that it has an extended history of usage, which means that you have a community of users that you can easily tap when you need some help.
If you are new to programming, this might feel like a daunting text editor to use, but the steep learning curve will pay off in the end. By learning how to code through hacking right away, you will be able to get a good grasp of Python as you experience it using different tools that were already made by other hackers. If you are gunning to develop a web app for your hacks, then this is probably the IDE that will work best for you.
Chapter 2: Python Basics Your goal, of course, is to make Python go beyond printing a text. To do that, you will need to learn other concepts that are essential in a Python script. You will also want to create a script that is easy for you to understand and review in the future, just in any case you want to improve it and turn it into a working tool for your hacks.
In order to take inputs and manipulate them in order to get certain results, you will first need to learn how variables and constants work in this programming language.
Comments These are statements that come after the symbol. These pieces of texts allow you to: Explain the problems that you are aiming to overcome or solve in your program Take note of the important assumptions, details, and decisions that you want to perform in the code Making notes in your code does not only remind you what you want to achieve in your code, but also help readers that will be using your program understand what lines of code are supposed to do.
Literal Constants Literal constants are named as such because you take these pieces of text for their literal value. These constants can be: Numbers They can be integers plain whole numbers or floats numbers that have decimal points Strings These are sequences of characters, which you can specify using single quote, double quotes, or triple quotes. Take note that single and double quotes function similarly in Python, and that you can express them freely inside triple quotes.
Here is an example: Strings are also immutable, which means that you cannot change a string once you have created it. How to Format Strings There are instances in which you will want to construct strings from a different piece of information.
To do this, you will need to use the method. Just like what the name means, variables have varying values, such as real numbers, strings, Booleans, dictionaries, or lists, which you can access through certain methods.
Take a look at this sample code: In this example, you are able to define the variable named port, which is going to be used to store the integer 21, and the variable named banner, which is going to hold a string. In order to combine these variables together as a single string, you will need to use the variable port through the use of the str function.
Since you need to quickly access the data you stored, you need to assign names to variables. This is where identifiers come to play.
Identifiers work like code names that you use to point out to something that you have used in your code or program. Here are some rules that you need to follow when assigning them: The initial character should be a letter of the alphabet or an underscore. The remaining characters should consist of underscores, letters, or digits They are case-sensitive, which means that mycode and myCode do not call out the same value and not interchangeable when you assign them as an identifier.
Objects Things that are referred to as anything in the code that exists in Python are called objects.
If you are migrating to Python from another programming language, you need to take note that everything in Python, including string, numbers, and functions, is classified as an object. Lists Python allows you to make use of a list data structure which is extremely useful when it comes to storing collections of objects. As a programmer, you can create lists that contain different types of data. At the same time, you can also make use of several built-in techniques in Python that will allow you to insert, index, count, sort, append, remove, pop, and even reverse items in a list.
Take a look at this example: Using the above code, you were able to create a list through the method append , print all the specified items, and then manage to sort the items before you asked the program to print them again. Dictionaries are extremely helpful in creating hacking scripts. For example, you can create a scanner that is designed to exploit vulnerabilities of a particular system, such as open TCP ports. If you have a dictionary that will display service names for corresponding ports that you want to exploit.
For example, you can create a dictionary that will allow you to look up the ftp key, and then provide you an output of 21, which corresponds to a port that you may want to test.
You can also use dictionaries to perform brute force attacks to crack an encrypted password. What makes Python even better is that you can code your own dictionaries and use them in other scripts that you may want to develop in the future.
When you create a dictionary, keys should be separated from their corresponding value with a colon, and the items should be separated using commas.
In the following example, you will be able to use the. Take a look at this example: Now that you know the basic concepts that make Python scripts perform tasks, you are now ready to start using them in your own script. In the next chapter, you will learn how a readable Python script should look like.
In this chapter, you will learn how to use some of the most basic concepts to run simple commands and format your Python codes in such a way that it will be easier for you to understand and document them later. That entire line is considered a statement because it indicated that something should be done, which is connecting the said variable to a numerical value. Afterwards, you printed out the value of i by using the print command.
Afterwards, you added 1 to the given value that you stored in the variable i, and then you saved it. When you use the print statement again, you get the value of 6. At the same time, you also assigned a literal string to the variable s and then proceeded to use the print statement. Physical and Logical Lines What you see when you type out a program is called a physical line.
What Python gets when you type a statement is called the logical line. With this said, this programming language assumes that every physical line that you see corresponds to a given logical line.
While you can use more than one logical line on a physical line by using the semicolon ; symbol, Python encourages that programmers like you input a single statement in order to make your codes more readable. This way, you will be able to see lines that you are working on and avoid possible confusion when you are working on two different logical lines and get lost on what you are supposed to work on.
Indentation Python is one of the programming languages out there where white space, especially the space at the beginning of each line of code is important.
By using indentation, you can group together blocks, or statements that belong together. As a rule of thumb, see to it that you are using the same indentation when you are working on similar statements. Also remember that using the wrong indentation can make your code prone to error.
Take a look at this example: When you run this code, you will get this result: Python recommend that you use four spaces for your indentations. Typical good text editors will do this for you. As long as you are consistent with the spaces that you are using, you will be able to avoid unexpected results in your code.
Now that you know the basics, you can now start learning the more interesting stuff! Chapter 5: Operators and Expressions Most of the statements also called logical lines that you will be writing in your code will include expressions. Expressions are divided into operands and operators. Operators are essentially functions that do something in your code, which are represented by symbols or keywords.
They usually require pieces on information that they can work on, which are called operands. Python Operators Take a look at how expressions look like in an interpreter prompt: When you evaluate expressions in an interpreter prompt and you used the right syntax, you will be able to see the result that you are expecting right after the logical line.
