Hacking using java

To achieve this, we need to run the JavaSnoop tool using the startup. We can inject JavaSnoop to an already running process by selecting from the available list of running processes. The main interface of the JavaSnoop tool is divided into four parts as shown in the diagram below. In this part, we select the class or method that needs to be hooked or intercepted. The interface provides a button to add a new Hook. We can then add a method from a specific class available from the list, as shown in the snapshot below:.

This part provides features for setting various options for intercepting the method calls. We can set regular expression conditions for matching and intercepting the traffic from the method calls. A snapshot is shown below:. This part of the interface helps in deciding what to do with a particular hook that we select from the part one of the interface.

It provides various options like the following:. The output from the hooks and the decompiled classes from the target application are shown up in this area. In this article, we look at two sample Java based applications and learn to intercept the traffic in the JavaSnoop tool:. A Java applet is an applet delivered to users in the form of Java bytecode. It is difficult to intercept the traffic from an applet that is a part of a web page.

We see an example of intercepting the traffic from an applet using JavaSnoop tool. Step 1: We have a sample login applet embedded into the web browser, which takes the user credentials and forwards it to the server for authentication. In order to intercept the traffic from the Java Applet, we use the method hooking techniques of JavaSnoop to intercept the traffic. The snapshot below shows the Login Applet with the user credentials entered into the input fields.

Step 3: Attaching the agent into the running applet will open the JavaSnoop interface. We can then select the classes and the respective methods to be hooked for intercepting the traffic.

We select the required class for which the methods are to be hooked, as shown below:. Step 5: The screenshot below shows the JavaSnoop interface containing the hooked methods and the conditions applied on the methods for intercepting the Java applet traffic. Step 6: As soon as we submit the user credentials on the Login applet, the tool intercepts the traffic and provides the user with a pop-up window for editing and forwarding the intercepted traffic.

In the section above, we learned to intercept the traffic for Java Applets. In this section, we will learn to intercept the traffic for JAR applications. Since JavaSnoop makes application data and traffic easy to tamper with, figuring out the right method to hook becomes a difficult part of the assessment. This mode is very useful in larger applications, where identifying of the correct class and method becomes difficult.

Despite what you may think, Perl codebases still occupy a large portion of corporate tools. Although this hacking programming language has long lost the charm it once had, many old systems still use Perl.

As it was the go-to solution for building legacy Unix software , this is still one of the best programming languages for hacking into such old machines.

A polyglot hacker will use Perl for crafting different parts of his hacking programs — from building exploits to building payloads and backdoors. One of the greatest hacking programming languages, LISP was the go-to solution for crafting innovative solutions to software problems among old-school hackers. Although the language has lost most of its appeal due to its somewhat complicated programming style and the emergence of verbose languages like Python and Ruby, those who know LISP are the most respected in the hacker community.

It is the best programming language for hacking into complex networks and will also earn you notoriety among fellow hackers. Although not exactly a full-fledged programming language, proficiency in Bash is a must if you want to master hacking programming. Bash is the default command shell in most Unix systems, and every major server is built on top of Unix.

It can be thought of like the swiss army knife of modern hacking programs and is a must for security enthusiasts. Assembly is thought to be the best programming language for hacking primitive systems, one of the most powerful yet hard to learn a hacking coding language.

What makes Assembly most suitable for developing fast and effective hacking programs is its ability to manipulate low-level system processes at ease. So, if you can withstand its steep learning curve, the result will be gratifying. The scheme is one of the two mainstream dialects of LISP that is still widely used in the industry. The scheme is a general-purpose programming language that supports multiple hacking programming paradigms — including functional programming and imperative programming.

Lua is a very lightweight language that can run smoothly on almost every embedded system. The language is fast and comes with a relatively simple yet powerful C API that allows ethical hackers to forge potential hacking programs to penetrate such systems. Thus, it can be the best programming language for hacking into systems that run on embedded hardware like smartwatches, smart TVs, and lots of other IoT devices.

No list for the best programming language for hacking is complete without mentioning HTML. It stands for HyperText Markup Language and glues the whole internet together. So, you should already be able to guess its necessity. Moreover, learning HTML is not that tough either. So, we suggest you invest some time behind mastering your HTML basics properly. It will prove to be an essential investment when moving forward and starting curating more complex hacking programs. A professional, ethical hacker is someone who can look beyond the languages or hacking programs and realize the bigger picture.

As different types of attacks suit different types of hacking programming, curating a perfect strategy is a must. Albeit, our outline of the 15 best programming languages for hacking can tackle every kind of attack and adapt well to different approaches.

We suggest you take each of your endeavors at a time and employ the best hacking coding language suited to that particular attack. HTML is no programming language, its a markup language but anyway… I should focus on python more I guess. But I want to learn something, can u suggest some language and website to become a ethical hacker ….

There are many online programming learning websites but the one I would suggest is CodeCademy. This is the one i used when i was first starting to program before I went to College for Cyber Security classes and starting early is better and the more languages you become fluent in the easier it is to understand how to complete a task because sometimes you will have multiple ways to complete it and knowing many can help you find the easiest way to complete it.
