Arcanus Framework : Hacking Linux OS Part 1

Hello aspiring hackers, till now we have only seen hacking windows operating systems with customized payload generators. Today we will see hacking Linux OS with Arcanus framework.

Although not as great as Windows, people using Linux OS are growing day by day. In my opinion, Linux OS is a bit easy to hack with payload generators as there is a general myth that Linux is immune to malware. Some of my friends use Linux as dual boot to keep themselves safe from virus.

Ok, now let us see how to hack Linux OS with Arcanus Framework. Start and select the option 3 since we are generating a Linux payload. If you are new to Arcanus Framework, go here.

Hit Enter. Enter your IP address (Kali Linux in this case) and the listening port as shown below.

Hit Enter. It will generate the payload in the same directory start to automatically listen for a reverse shell as shown below.

Send the generated payload to our victim. When he runs it, we should get a shell on his system as shown below.

Upgrade command shell to Meterpreter session

Hello friends.. I took a long break from the blog (actually I was channeling my energy on my monthly magazine Hackercool). But I am here now back with a bang or should I say hack. Ok, Most of the times we only get a command shell on our target while hacking, although we wish we got a meterpreter session .Today we will see how to upgrade the command shell to meterpreter.

First thing we need is to background the current command shell session. Hit on CTRL+C. Don’t abort the session altogether. If it happened by mistake ( like it happened to me below), select “no” when it asks whether to abort a session. Then hit CTRL+Z and select Yes. Your session has been sent to background. Remember the session number.

Load the command shell to meterpreter upgrade module. We need only one option, the session id we sent to background.

Specify the session id and run the exploit as shown below. We will get the meterpreter session.

Type command “sessions -l” to see all our sessions as shown below.

We can load the meterpreter session as shown below.

If you found that helpful. Please check out my monthly magazine Hackercool.

Windows hacking with Hercules Framework : Part1

Good afternoon friends. Recently our have learnt about windows hacking with Arcanus framework. Today we will learn about another payload generator that helps us in bypassing antivirus ( till date) during pentest of Windows machines. That is Hercules framework.

Let’s start by cloning Hercules framework from github as shown below.

After cloning, a new directory with name HERCULES will be created. Move into that directory and do a “ls”. We should see a file named “Setup”. First change the permissions of this file using chmod as shown below. Once we get execute permissions on the Setup file, execute the file using command “./Setup“.

The setup automatically installs Hercules as shown below and

successfully ends as shown below. You have successfully installed Hercules framework in Kali Linux.

Type command “HERCULES” to start the framework. It’s interface looks like below. In this part, let’s generate a payload. Enter option “1”.

Select what type of payload you want to create. There are four payloads as shown below. I am choosing the first one. You can choose appropriately.

After we select the type of payload we want to create, we need to enter some options. Let us see the options it provides. LHOST and LPORT are self explanatory. Choosing Persistence function adds our running binary to Windows startup registry so that we can have persistent access to the target. Since we have already know how to create a persistent backdoor we will not enable it here.

Migration function triggers a loop that tries to migrate to a remote process. UPX ( Ultimate Packer for executables ) is an open source executable packer. To those newbies who have no idea what packers are, they are used to compress the executables. Software vendors also use them to obfuscate the code. We will see more about packers in our future howtos.

Concerning this howto, remember that enabling migration, persistence and UPX functions may increase the chances of your payload being detected by Antivirus.

Here I have only enabled the UPX function so the packing process begins as shown below.

Once the packing process is over, your final binary file is stored with the name you have given to it. I named it as “res”.

Next start the listener on Metasploit as shown below and send the binary file to our target. Once he clicks on our executable file, we will get the meterpreter session as shown below.

In our part2 of this howto, we will see how to bind our payload to other executables.

Backdoor Windows with Metasploit

Good morning aspiring hackers. Today we will see how to create a persistent windows backdoor with Metasploit. As soon as we get meterpreter shell on the target system, it is a good practice for a hacker ( pen tester ) to create a backdoor. Coming to that, what exactly is a backdoor? A backdoor is something which gives us continuous access to our target system.

Next question that comes to our mind is why we need to create a backdoor? Most of the methods we used to take control of our target systems are based on the vulnerabilities our target has. So once the vulnerabilities are patched, access to the target is lost. That’ why we need to create a backdoor.

This backdoor also answers a question many people ask like, once we get a meterpreter shell, can we shut down our machine? If we restart, will the connection be gone or still intact? .This backdoor needs only one one condition to be fulfilled. The target system should be out of its safest mode. i.e it shouldn’t be turned off .
Now let us see how to create a persistent windows backdoor with Metasploit. In the meterpreter session we acquired on the target system, run the command “run persistence -h“. It will show you all the options we can set for our backdoor. All the options are self explanatory.

Now I want my backdoor to start as soon as the system starts. So I chose ‘X’ option. After starting, I want it to make connection attempt to my attacker system every three seconds, so I kept the interval(i) as 3. The port on which connection should be made is 443. The option (r) is remote system’s IP address i.e the IP of the system to which the connection should be made.

Remember this script will be installed on the target system. Run the script. As you can see, the file is installed in the autorun.

Now it’s time to start a listener on our attacker system. We have done it many times as shown below.

Change the options accordingly as we set in the persistence script and start the handler. If the system is live, we will get the meterpreter shell as shown below.

Crack password hash es with Kali

Hello aspiring hackers. In this article, we will learn how to crack password hash es using kali. n many hacking scenarios, we encounter hashes. To those newbies who have no idea what hashes are, they are encrypted text ( literally we can’t call it text ). Normally they are used to encrypt passwords for website users, operating system users etc. Today our tutorial is about cracking hashes.

For this howto, we will use NewsP Free News Script 1.4.7 which had a credential disclosure vulnerability as shown below. Imagine we got the username and password hash as shown below. The only thing that stops me from accessing the website is password in encrypted format.

Image explaining how to crack hash es with kali linux

The first step in cracking hashes is to identify the type of hash we are cracking. Kali Linux has an inbuilt tool to identify the type of hash we are cracking. It’s hash-identifier. Open a terminal and type command hash-identifier.

Enter the hash we need to crack as shown above and hit ENTER. It will show the possible hash type as shown below. In our case, it is MD5 or a variant of it.

We can also use another tool hashid for similar purpose. It’s syntax is as shown below.

We know what the type of hash is. Now, it’s time to crack the hash. We will use a tool called ‘findmyhash’. To use this tool, we need to specify the hash type ( which we already know ) and hash after it as shown below. This tool tries to crack the hash by using various online hash crackers available.

After successfully cracking the hash, it will display us the corresponding password as shown below. In our case, the password is admin.

That’s all in how to crack password hash with Kali. Learn how to do SMB enumeration with Kali.
