How to Encrypt Your DNS for More Secure Browsing



We’ve been touting the benefits of third-party DNS servers for a while now, but one additional benefit that might be of interest is the ability to encrypt all of your DNS requests, further protecting you from anybody spying on you in the middle.
DNSCrypt, from the great team at OpenDNS, is the simple solution that we’ll use to add encryption between your computer and the DNS server. It’s a lightweight solution that works on either Windows or Mac — sadly no mobile support so far.
What this tool is actually doing is creating an encrypted connection to any of the supported DNS servers, and then creating a local DNS proxy on your PC. So when you try to open howtogeek.com, your browser will send a regular DNS query to the 127.0.0.1 localhost address on port 53, and that request will then be forwarded through the encrypted connection to the DNS server.

Man In The Middle Attack With Kali Linux


It’s one of the simplest but also most essential steps to “Conquering” a network. Once a hacker has performed a “Man In The Middle” attack (MITM) on a local network, he is able to perform a number of other “Side-kick” attacks. This includes, cutting a victim’s internet connection; intercepting Emails, logins, and chat messages; and many others.
And only one tools is needed for this attack:
An install or Live boot of Kali Linux, a well-known OS containing a collection of hundreds of penetration testing tools.

If you have that, then proceed to the tutorial below, and we’ll demonstrate how to perform this powerful attack.

Advanced Networking Commands


In one of our previous tutorials, you've learned how to use basic commands in Command Prompt. Now it's time to take things to the next level and show how to use some of the more advanced commands. The first set of advanced commands contains useful network commands which facilitate the following: viewing information about your network devices and connections (assigned IP Address, the MAC of the network card), checking the availability of a certain host and displaying a wealth of networking and ports information
.

Retrieving Information about Your Network Connection

To obtain detailed information about your network connection, use the ipconfig command. Type ipconfig in Command Prompt and press Enter. As you can see below, a list with the network devices existing on your system and their IP addresses is displayed. You get also details such the default gateway, subnet mask or the state of the network adapter.

How To Bypass Antivirus Detection Making An Executable FUD



So in this tutorial we will show you step by step on how to make a virus Fully Undetectable from all the antiviruses. Their are lots of approaches, however here we will take a look at how to make an executable FUD using msfencode.

Requirements
  • Metasploit ( Kali Linux )
Attention
We are using some harmless test files but don’t infect people with any real viruses. That would be a crime.
Purpose
Antivirus protects machines from malware but not all of it .there are ways to pack malware to make it harder to detect. well use metasploit to render malware completely invisible to antivirus.
Creating a Listener
This is a simple payload that gives the attacker remote control of a machine. It is not a virus ant won’t spread, but it is detected by antivirus engines. In Kali Linux in a Terminal windows execute these commands:

msfpayload windows/shell_bind_tcp LPORT=2482 X > /root/listen.exe

ls -l listen.exe

OpenSSL Heartbeat (Heartbleed) Attack Using Metasploit



This module implements the OpenSSL Heartbleed attack. The problem exists in the handling of heartbeat requests, where a fake length can be used to leak memory data in the response. Services that support STARTTLS may also be vulnerable. The module supports several actions, allowing for scanning, dumping of memory contents, and private key recovery.

Now Open Kali Linux terminal type msfconsole
