Focus on learning to think like a programmer instead of learning individual languages. Focus on similar concepts in all programming languages. It along with assembly language teaches something very important in hacking: how memory works. Python and Ruby are high-level, powerful scripting languages that can be used to automate various tasks.
Perl is a reasonable choice in this field as well. Bash scripting is a must. You can use Bash to write scripts, which will do most of the job for you. Assembly language is a must-know. It is the basic language that your processor understands, and there are multiple variations of it. You can't truly exploit a program if you don't know assembly. Get an open-sourced Unix-based system and learn to use it.
There is a wide family of operating systems that are based on Unix, including Linux. The vast majority of web servers on the internet are Unix-based.
So you'll need to learn Unix if you want to hack the internet. There are many different distributions of Unix and Linux. The most popular Linux distribution is Ubuntu. You can Install Linux as your primary operating system, or you can create a Linux virtual machine. You can also Dual Boot Windows and Ubuntu.
Part 2. Secure your machine first. To hack, you must need a system to practice your great hacking skills. However, make sure you have the authorization to attack your target.
You can either attack your network, ask for written permission, or set up your laboratory with virtual machines. Attacking a system without permission, no matter its content is illegal and will get you in trouble. Boot2root are systems specifically designed to be hacked.
You can download these systems online and install them using virtual machine software. You can practice hacking these systems. Know your target. The process of gathering information about your target is known as enumeration. The goal is to establish an active connection with the target and find vulnerabilities that can be used to further exploit the system.
There are a variety of tools and techniques that can help with the enumeration process. The following is some information you want to gather: [5] X Research source Usernames and group names. Network shares and services IP tables and routing tables. Service settings and audit configurations. Applications and banners. Test the target. Can you reach the remote system? While you can use the ping utility which is included in most operating systems to see if the target is active, you cannot always trust the results — it relies on the ICMP protocol, which can be easily shut off by paranoid system administrators.
You can also use tools to check an email to see what email server it uses. You can find hacking tools by searching hacker forums. Run a scan of the ports. You can use a network scanner to run a port scan. This will show you the ports that are open on the machine, the OS, and can even tell you what type of firewall or router they are using so you can plan a course of action.
Find a path or open port in the system. An open port 22 is usually evidence of an SSH secure shell service running on the target, which can sometimes be brute-forced. Crack the password or authentication process. There are several methods for cracking a password.
They include some of the following: Brute Force: A brute force attack simply tries to guess the user's password. This is useful for gaining access to easily-guessed passwords i.
Hackers often use tools that rapidly guess different words from a dictionary to try to guess a password. To protect against a brute force attack, avoid using simple words as your password. Make sure to use a combination of letters, numbers, and special characters. Social Engineering: For this technique, a hacker will contact a user and trick them into giving out their password. For example, they make a claim they are from the IT department and tell the user they need their password to fix an issue.
They may also go dumpster-diving to look for information or try to gain access to a secure room. That is why you should never give your password to anybody, no matter who they claim to be. Always shred any documents that contain personal information. Phishing: In this technique, a hacker sends a fake email to a user that appears to be from a person or company the user trusts. The email may contain an attachment that installs spyware or a keylogger.
It may also contain a link to a false business website made by the hacker that looks authentic. The user is then asked to input their personal information, which the hacker then gains access to. To avoid these scams, don't open emails you don't trust. Log in to business sites directly instead of clicking links in an email. ARP Spoofing: In this technique, a hacker uses an app on his smartphone to create a fake Wi-Fi access point that anyone in a public location can sign into.
Hackers can give it a name that looks like it belongs to the local establishment. People sign into it thinking they are signing into public Wi-Fi. The app then logs all data transmitted over the internet by the people signed into it. If they sign in to an account using a username and password over an unencrypted connection, the app will store that data and give the hacker access.
To avoid becoming a victim of this heist, avoid using public Wi-Fi. If you must use public Wi-Fi, check with the owner of an establishment to make sure you are signing in to the correct internet access point.
Check that your connection is encrypted by looking for a padlock in the URL. Stuxnet is a widely known example of a national security backed hacking strategy. Stuxnet is a computer worm that attacked Iranian nuclear facilities.
The worm is presumed to be a joint effort between American and Israeli intelligence agencies. National cyber hacks tend to be extremely successful, as their teams have the resources and patience to find vulnerabilities and exploit them.
As touched on earlier, penetration testers or white hats hack systems to test vulnerabilities to improve security. Many hackers hack simply because they can. The first category of hacks are never-seen-before vulnerabilities, also known as zero-day vulnerabilities.
They are the most damaging because they are not patched. Security teams do not know how to defend against them, and often don't even realize a system has been compromised. The hackers behind these attacks are highly-skilled, scary-smart hackers.
Zero-day attacks are usually carried out on multinational businesses or national security systems. Heartbleed was a zero-day exploit publicized in against Linux servers.
Shockingly, there is no way of knowing how many people knew about and used the exploit before it was made public—and the code that Heartbleed exploited was introduced three years before its vulnerabilities were ever publicized. The majority of present day hacks use code that has been written by someone else and released into the wild.
These hacks are fairly easy to defend against if a computer is updated. Security organizations are very good at pushing security updates once hacks have been discovered and the code is released. If a kid can find a script online, so can a security professional. Here is an easy, step-by-step process for hacking a computer:.
Social engineering , the practice of manipulating people to divulge information, is by far the easiest method of gaining access to a computer system. This plugin saves you time by allowing you to encode and decode selected text via the context menu.
In addition to that, the context menu can also be customized. The following functions can be performed with this extension:. Download: d3coder for Google Chrome. It equips you with a web spider that has the ability to crawl an entire website and follow every link within it.
You can restrict its depth via regular expressions, and you can also pause or stop the spider. With this plugin, you can easily identify any broken links within a website and report them to your client. You can also use this web crawler to determine whether there is any confidential or sensitive information within the target site that could be exploited. Ethical hackers often have many tabs open at the same time.
As you probably already know, this will fill up your browser cache pretty quickly and may even cause issues when viewing a webpage.
By installing this extension, you can work much faster because it automatically clears the browser cache before loading a new page. You can also easily enable or disable the plugin with a single click. Download: Cache Killer Chrome Extension. In the same way an open window or door is tempting for house burglars, unused open ports are a goldmine for cybercriminals. With the Open Port Check Tool, you can easily identify open ports that are not in use.
By doing this, you can identify port vulnerabilities that need to be addressed. Wireshark is another example of an open-source tool. However, this piece of software is used to analyze network traffic. So if someone is looking for a way to improve their network security, this hacking tool and others like it might be the step towards the right direction. Wireshark works on around network protocols, and it runs on all major operating systems.
To put it simply, this application is a good example of a tool that is intended for one particular sphere networks, in this case. To discover software vulnerabilities, someone might prefer to use Metasploit. Rather than being one single application or utility, it is a whole open-source security project. It means that there are different hacking tools under the Metasploit umbrella, and they can be used to test different aspects of the software.
For example, some tools can be used to run security vulnerability scans, run remote attacks on potentially vulnerable software, evade detection systems, and so on. On top of that, Metasploit comes in three different versions, which you can choose depending on what you need. Pro is intended for IT security teams, Community can be used by small companies, and Framework is for developers and researchers.
This tool is intended for data collection. It can easily ascertain connections between phone numbers, email addresses, companies, people, social network profiles, and so on. You can also use this tool to analyze connections and correlations between such infrastructures as DNS servers, files, web pages, domain names, IP addresses, and others. Also, like most of the tools on the market, this application also works on Windows, Linux, and MacOS.
So, as you can see, there are various ethical hacking tools out there that can help companies and users analyze their networks, systems, software, apps, etc. Automatic hacking tools are going to evolve further and, as a result, it will make it easier for companies to fix system vulnerabilities before they get exploited by cybercriminals.
With the growing online security requirements, quite a few corporate and individual users turn to password encryption in order to protect their sensitive information.
Normally, passwords that are stored within a
