Decompiling & Recompiling Android APKs

Decompiling & Recompiling Android APKs

(Decompiling & Recompiling Android APKs using APK Tool)

APK Tool Introduction.

A tool for reverse engineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making some modifications. It also makes working with an app easier because of the project like file structure and automation of some repetitive tasks like building apk, etc.

Quick Checks.

1. Check if Java 1.7 is Installed.

2. Does executing java -version  on command line / command prompt return 1.7.

C:\Windows\system32>java -version
java version "1.7.0_111"
Java(TM) SE Runtime Environment (build 1.7.0_111-b14)
Java HotSpot(TM) Client VM (build 25.111-b14, mixed mode, sharing)

3. If not Install Java 7 and make it default.

Installation.

• Windows:

1. Download Windows wrapper script (Right click, Save Link As  apktool.bat )
2. Download apktool-2 (find newest here).
3. Rename downloaded jar to  apktool.jar .
4. Move both files ( apktool.jar  &  apktool.bat ) to your Windows directory (Usually  c://Windows ).
5. If you do not have access to  c://Windows , you may place the two files anywhere then add that directory to your Environment Variables System PATH variable.
6. Try running  apktool  via command prompt.

Step 1: Finding Framework Files.

There are two types of framework files, which should be extracted from your Android device. These files can be found in the root of your android device. (Note: Framework files are in .apk format).

/system/framework/

/data/system-framework/

/system/app/

/system/priv-app/

These files are usually named as "resource" ,"res" or "framework" .

                            

Step 2: Installing Framework Files.

1. Make a new folder.
2. Paste the two framework files (That you grabbed from your android device).
3. Paste the apk which you desire to edit, in that particular folder.

     4. [Shift] + [Right Click]. In that folder location. Then choose "Open command window here".

     5. Type the following commands.

E:\Test>apktool if framework-res.apk
I: Framework installed to: 1.apk 

E:\Test>apktool if twframework-res.apk
I: Framework installed to: 2.apk 




Step 3: Decompiling APK .

1. After installing the framework files its the time to decompile the apk.

2. Use the following command to decompile the apk.

E:\Test>apktool d ABCHHackerz.apk
I: Using Apktool 2.2.1 on ABCHHackerz.apk
I: Loading resource table...
I: Decoding AndroidManifest.xml with resources...
I: Loading resource table from file: C:\Home\AppData\Local\apktool\framework\1.apk
I: Regular manifest package...
I: Decoding file-resources...
I: Decoding values */* XMLs...
I: Baksmaling classes.dex...
I: Copying assets and libs...
I: Copying unknown files...
I: Copying original files...

  

3. The files from the apk are been extracted in the folder. Replacements, Script Editing, Other changes can be done in there.

Step 3: Re-Compiling APK .

1. When all the needed changes are been finished. Its the time to Re-Compile the extracted folder.

E:\Test>apktool b ABCHHackerz
I: Using Apktool 2.2.1 on ABCHHackerz
I: Checking whether sources has changed...
I: Smaling smali folder into classes.dex...
I: Checking whether resources has changed...
I: Building resources...
I: Building apk file...
I: Copying unknown files/dir...

2. After the building process completes. The compiled apk is stored in the Extracted folder.

ABCHHackerz(Extraxted Folder)\dist\ABCHHackerz.apk(Compiled APK)

3. The Compiled APK is currently Unsigned. So you can't install it yet. You have to sign it for installing it on your device.

Step 3: Signing APK .

1. For Signing an apk you'll need APK Editor Pro (Download).

2. Install APK Editor Pro on you Android Device.

3. Further Instructions are in the following Video.

Pokemon Go Roam App (Only for Android Devices). UPDATED....!!

Pokemon GO Roam Android App

Pokémon GO Roam Android Application is a hack tool for the ridiculously famous and viral Android, IOS game Pokémon GO. It is built on Niantic’s Real World Gaming Platform and will use real locations to encourage players to search far and wide in the real world to discover Pokémon. Pokémon GO allows you to find and catch more than a hundred species of Pokémon as you explore your surroundings.

The Pokémon video game series has used real-world locations such as the Hokkaido and Kanto regions of Japan, New York, and Paris as inspiration for the fantasy settings in which its games take place. In Pokémon GO, the real world will be the setting!

Get on your feet and step outside to find and catch wild Pokémon. Explore cities and towns around where you live and even around the globe to capture as many Pokémon as you can. As you move around, your smartphone will vibrate to let you know you're near a Pokémon. Once you've encountered a Pokémon, take aim on your smartphone's touch screen and throw a Poké Ball to catch it. Be careful when you try to catch it, or it might run away! Also look for PokéStops located at interesting places, such as public art installations, historical markers, and monuments, where you can collect more Poké Balls and other items.

How to Modify .exe Files or a Software HIjacking.

How to Modify .exe Files or a Software HIjacking.

Hey, Hackerz Here's our new post on Software Hijacking or somewhat exactly meant as Reverse Engineering the Compiled .exe, .dll, .sys, .msstyles, .cpl, .ocx, .acm, .ax, .dpl, .bpl, .mui, .scr files. Here are few sets of programs which can be used for reverse engineering the particular executable programs.

1. PE Explorer

PE Explorer hosts too many tools to show them all on one page, so we took only few screenshots to give you an idea of how it looks like. Take the PE Explorer Feature Tour to learn more.

Export, Import, Delay Import Viewers

The Export, Import and Delay Import Table viewers allow you to view all the external functions the executable is using, and the results are categorized based on the DLL or library which contains them. A very useful feature here is the Syntax Viewer, which displays the calling syntax for functions it knows about and allows you to expand the syntax database with your own definitions.

 

Resource Editor

The Resource Editor offers a thorough look at all of the resources (bitmaps, jpeg, png, icons, strings, etc) in the file, and allows you to make modifications without needing to recompile the source code.

Section Editor

Restoring the original values of sections' offsets to real data in the file is not an easy task. In many respects it depends on intuition and supposition, and is practically impossible to completely automate the given process. The Section Editor allows you to facilitate a solution to these problems.

Disassembler

PE Explorer Disassembler utilizes a qualitative algorithm designed to reconstruct the assembly language source code of target binary win32 PE files (EXE, DLL, OCX) with the highest degree of accuracy possible.

Dependency Scanner

Dependency Scanner displays a list of all the external DLLs the selected PE file depends on, and iteratively scans each of these files for its dependencies. The Dependency Scanner opens a second window and displays the dependencies on the left in a hierarchy, with version information on each of these files displayed in the right-hand pane as you click on them.

2. Resource Hacker

1. View resources in Win32 executable files

(*.exe, *.dll, *.cpl, *.ocx) and in Win32

resource files (*.res) in both their compiled

and decompiled formats.

2. Extract (save) resources to file in:

*.res format; as a binary; or as decompiled

resource scripts or images.

Icons, bitmaps, cursors, menus, dialogs,

string tables, message tables, accelerators,

Borland forms and version info resources can

be fully decompiled into their respective

formats, whether as image files or  *.rc text

files.

3. Modify (rename or replace) resources in

executables. Image resources (icons, cursors

and bitmaps) can be replaced with an image from

a corresponding image file (*.ico, *.cur, *.bmp),

a *.res file or even another *.exe file.

Dialogs, menus, stringtables, accelerators and

messagetable resource scripts (and also Borland

forms) can be edited and recompiled using the

internal resource script editor.

Resources can also be replaced with resources

from a *.res file as long as the replacement

resource is of the same type and has the same

name.

4. Add new resources to executables.

Enable a program to support multiple languages,

or add a custom icon or bitmap (company logo

etc) to a program's dialog.

5. Delete resources.

Most compilers add resources into applications

which are never used by the application.

Removing these unused resources can reduce an

application's size.

LOIC (Low Orbit Ion Canon) DDos Attacker

LOIC (Low Orbit Ion Canon) DDos Attacker

About The Original LOIC Tool :

The LOIC was originally developed by Praetox Technologies as a stress testing application before becoming available within the public domain. The tool is able to perform a simple dos attack by sending a large sequence of UDP, TCP or HTTP requests to the target server. It’s a very easy tool to use, even by those lacking any basic knowledge of hacking. The only thing a user needs to know for using the tool is the URL of the target. A would-be hacker need only then select some easy options (address of target system and method of attack) and click a button to start the attack.

The tool takes the URL of the target server on which you want to perform the attack. You can also enter the IP address of the target system. The IP address of the target is used in place of an internal local network where DNS is not being used. The tool has three chief methods of attack: TCP, UDP and HTTP. You can select the method of attack on the target server. Some other options include timeout, TCP/UDP message, Port and threads. See the basic screen of the tool in the snapshot above in Figure 1.

The LOIC version used by Anonymous group attacks was different than the original LOIC. It had an option to connect the client to the IRC (Internet Relay Chat). This allowed the tool to be remotely controlled, using the IRC protocol. In that case, the user machine became part of a botnet. A botnet is a system of compromised computer systems connected to each other via the internet, which are in turn controlled by the attacker who directs the malware toward his / her target. The bigger the botnet, the more powerful the attack is.

Type of attacks: As I’d mentioned previously, the LOIC uses three different types of attacks (TCP, UDP and HTTP). All three methods implement the same mechanism of attack. The tool opens multiple connections to the target server and sends a continuous sequence of messages which can be defined from the TCP/UDP message parameter option available on the tool. In the TCP and UDP attacks, the string is sent as a plain text but in the HTTP attack, it is included in the contents of a HTTP GET message.

This tool continues sending requests to the target server; after some time, the target server becomes overloaded. In this way, the target server will no longer be able to respond to requests from legitimate users, effectively shutting it down.

Analysis of the attack :

UDP Attack: To perform the UDP attack, select the method of attack as UDP. It has port 80 as the default option selected, but you can change this according to your need. Change the message string or leave it as the default.

TCP Attack: This method is similar to UDP attack. Select the type of attack as TCP to use this.

HTTP Attack: In this attack, the tool sends HTTP requests to the target server. A web application firewall can detect this type of attack easily.

How to use LOIC to perform a Dos attack: Just follow these simple steps to enact a DOS attack against a website (but do so at your own risk).

HACK a Programming Language Developed by Facebook

The Hack language

Hack has deep roots in PHP. In fact, most PHP files are already valid Hack files. We made a conscious choice not to support a handful of deprecated functions and features that were incompatible with static typing (e.g. “variable variables” and the extract() function). We have also added many new features that we believe will help make developers more productive.

Our principal addition is static typing. We have developed a system to annotate function signatures and class members with type information; our type checking algorithm (the “type checker”) infers the rest. Type checking is incremental, such that even within a single file some code can be converted to Hack while the rest remains dynamically typed. Technically speaking, Hack is a “gradually typed*”* language: dynamically typed code interoperates seamlessly with statically typed code.

Within Hack's type system, we have introduced several features such as generics, nullable types, type aliasing, and constraints on type parameters. These new language features are unobtrusive, so the code you write with Hack will still look and feel like the dynamic language to which PHP programmers are accustomed.

However, Hack adds additional features beyond static type checking, including Collections, lambda expressions, and run-time enforcement of return types and parameter types.

Collections provide a clean, type-safe alternative to PHP arrays. We designed them specifically to work well with static typing and generics. The Collections API offers many classic higher-order functions such as map() and filter() to facilitate functional programming styles.

Lambda expressions give a concise syntax for creating closures. While PHP has closures, it requires the programmer to explicitly name the variables they need to use from enclosing scopes. With Hack's lambda expressions, we automatically infer these uses, saving you needless work. Lambda expressions make it more convenient to take full advantage of the Collections API.

Run-time enforcement of return types and parameter types (including scalar types like int and string) provides safety beyond what can be checked statically while type annotations are being gradually added to a codebase. Run-time enforcement helps programmers detect and diagnose certain kinds of problems more easily, and it helps HHVM's JIT produce more efficient code by making it safe to trust type annotations for optimization purposes.

Instantaneous type checking

During development, a PHP programmer typically goes back and forth rapidly between the source code and the browser. Engineers can iterate as quickly as they need, testing and tuning an experience until it's perfect.

Traditionally, a type checker would disrupt this feedback loop as it takes time to analyze the source code. We didn't want to slow the PHP workflow, so we came up with a new approach to reconcile instantaneous feedback with type safety.

Our solution was to architect the type checker as a local server that watches the filesystem. The server keeps all information about the source code in memory and automatically updates itself when a file changes on disk. This approach has paid off: the type checker typically runs in less than 200 milliseconds and rarely takes more than a second, making it easy to integrate into the development workflow without introducing a noticeable delay.

Code migration

Hack's type safety and refactoring benefits grow the more it is used within a codebase. Understanding that it would be difficult for some code to be completely transitioned to Hack right away, it was important to us that Hack be developed such that it can coexist directly with other PHP files as it is being introduced incrementally.

The rest of the conversion process, such as adding type annotations and using new language features, can be done as appropriate for the codebase. For example, a type annotation can be added for one function but left off another function, even in the same file. If a function parameter or class member does not have an explicit type annotation, the type checker considers its type to be dynamic, and it does not check the type of that value.

Within Facebook, we found that our engineers appreciated Hack enough that they started converting the majority of their own code voluntarily. With millions of lines of code in our tree, we also wanted some form of automation, so we built and use a number of code modification tools to assist the process (which we are releasing as part of Hack).

Don't worry, your PHP is safe!

HHVM is still a PHP runtime, and we intend to keep it that way. In fact, we are working hard to reach parity with PHP-5. One of HHVM's top priorities is to run unmodified PHP-5 source code, both for the community and because we rely on third-party PHP libraries internally.

HHVM is now a runtime that supports *both* PHP and Hack, so you can start to take advantage of Hack's new features incrementally.

Have fun with Hack!

We are delighted to open-source both Hack and the tools you can use to automatically convert your codebase. This is just the first step, and we are dedicated to continuing to evolve this software to make development even easier for both our own engineers and the broader community. Hack's value is *not* limited to big projects: with type information, good error messages, and fast feedback, small codebases can reap the benefits of Hack as well.

Next month, we will also introduce the language at the Hack Developer Day on the Facebook campus in Menlo Park, and we hope to see you there in person or online.

We would love to have your feedback on our work so far, and welcome you all to participate in the HHVM and Hack community.

Acknowledgements

There are many people who have contributed to the development of Hack.

The core Hack team consists of Julien Verlaguet, Joel Beales, Eugene Letuchy, Gabriel Levi, Joel Marcey, Erik Meijer, Alok Menghrajani, Bryan O'Sullivan, Drew Paroski, James Pearce, Joel Pobar, and Joshua Van Dyke Watzman.

A special thanks goes to our early community adopters for providing valuable feedback to make the language better: James Miller, Simon Welsh, Nils Adermann, Fabien Potencier, and Alexander Mols.

Hack is written primarily in OCaml. We would like to thank the Gallium team (INRIA) for the development of the OCaml language, and the Ocsigen team (CNRS - University of Paris Diderot - INRIA) for the development of the js_of_ocaml part of Ocsigen.
