How to block Facebook from your PC

Facebook wants to sell every Ad and you on the Web. The social network will show ads to non-Facebook users on other websites.

Companies like Facebook and Google offer you their services for free, but free always has a cost. Advertising pays the bills and the contributors, and these big companies separate themselves from serving up ads that are better targeted than other smaller networks. By tracking you across the web and building a profile (Big Data) that helps which ads you’re going to click most likely.

Block the Blue Coat Intermediate CA from Windows

Privacy and Anonymity

Privacy

Privacy is an increasingly rare commodity these days. To find out what kind of information is there about you do a search for yourself on Pipl.com, you might be surprised at the number of companies that claim to have information about you and your relatives.

That’s because your personal information, including your email address, phone number and daily activities on Social Networks and apps, are worth a lot of money to legitimate businesses, your new employer, government and bad guys (read hackers).

Force HTTPS On Your WordPress Site

I’m running my wordpress site for quite some time now.. My site is HTTPS enabled and signed with a certificate. HTTP was also possible in the past for reaching my site. In this guide i’m going to point all of the pages (including the administrative) to force HTTPS.

To simplify this, the guide will build into the following 3 parts:

  1. Force SSL for administrator pages (including the login page)
  2. Secure all normal pages with HTTPS
  3. Change .htaccess to redirect all HTTP to HTTPS

When all of this is completed you should have a WordPress site completely running secure with HTTPS.

OpenVPN in Kali Linux

This how to describes how to configure Kali to use a openVPN for securing your traffic.

Why should u use VPN?

Here’s my top 5 why you want to use a VPN service.

  1. VPN provides Privacy and hides your own External IP address.
  2. Use any network (public or private or free (hotspot WiFi) with encryption.
  3. Login to your home or Work network from anywhere with confidence of encrypted traffic.
  4. Bypass censorship and content monitoring  by goverments.
  5. Browse and bypass Firewall and censorship policy from Anywhere!

As you can see from the list above, VPN not necessarily hides everything. Search engines  like google, bing and yahoo can still recognizes you based on your cookies or account sign-in. So make sure you use tools like Bleachbit (clear browsing data etc) and enable plugins in your browser for tracking and ads (privacy badger, uBlock Origin or Privacy.net analyzer).

How to install BeEF on Ubuntu

BeEF stands for The Browser Exploitation Framework. It is a great penetration testing tool that focuses on the web browser.

Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, It looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. It will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context.
