CyberGhost – A superb Freeware for Anonymous Surfing

Tech2know — Tue, 20 Sep 2011 00:33:32 +0000

Now a days all of us use the web everyday without knowing that we leave personal information every time we visit a website. You leave behind a load of trails when you surf on the Internet, but not only on your PC. Each access provider knows exactly when you visited which websites. Many websites save your address and the details of what you looked at. Any time anyone visits a web server, they always unwittingly leave behind their IP address as an indication of their visit. It is also specified exactly in the server logs which content was transferred to this IP address, which content was downloaded and where on the website which link was clicked. The website is also often informed as to where you have come from.

There is little privacy on the Internet. Website operators would like to know what you’re interested in. Businesses want to know what you’re up to on the Internet. It’s time for you to protect yourself and your privacy. How ?

CyberGhost VPN is the answer to the question. I just came across this useful piece of software and used its free version.

CyberGhost is an important tool for protecting your privacy. CyberGhost VPN replaces the externally visible IP address, which users have received from their provider when they dial up to connect to the Internet, with a CyberGhost VPN IP address. The CyberGhost user shares this IP address with a number of other users. This procedure ensures that the CyberGhost VPN IP address should not be assigned to one particular CyberGhost VPN user.

Supported operating systems

Windows 7, Vista and XP(32/64 Bit). I installed it on Vista(32 Bit) and it worked fine.

Installation

Installation is pretty straightforward and won’t land you in ‘keep guessing’ mode . After installation you need to create an online account before you can use it. This is only for the first time.

Download

Well, we all communicate online with our friends, relatives, girl friends by using various means. For example, messengers. Be it Yahoo, Gtalk, or MSN. All serves same purpose of letting us communicate online.

There is another free communication platform about which many of us don’t know. Its called as RetroShare.

RetroShare is a Open Source cross-platform, private and secure decentralised communication platform. It lets you to securely chat and share files with your friends and family, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication. RetroShare provides file sharing, chat, messages, forums and channels.

Below is a screen shot :

Supported operating systems.

Windows(I tested it on Vista), Ubuntu, Mac.

Installation and prerequisite

You must install GPG4Win v1.1.4 in you are installing RetroShare under windows. Well, you don’t have to search for GPG4Win separately because win32 installer of RetroShare automatically installs it but you will need to first remove any more recent version of gpg4win.

Multiple simultaneous downloads / uploads
Search Friends
Messages
Forums
UPnP / NAT-PMP port forwarding support
GnuPG Authentication

One of the feature which I personally like about RetroShare is that

RetroShare is serverless, which means – unlike other messengers, you don’t* need to register, complete annoying registration forms and receive tons of ads. Sending a key to your friend by e-mail is enough to set up your own IM network. This also means no IM spam, because people you didn’t invite absolutely cannot connect.

Hacking a Facebook account costs $100 only

Tech2know — Sat, 19 Sep 2009 07:06:18 +0000

Panda Labs has discovered an online service that promises to hack into Facebook accounts for $100. They claim they will provide “clients” with login and password information to access any account on the social network.

The first thing they request you is to register in their site. The next step to hack an account was to provide them with the ID of the Facebook account you wanted to hack. Once the account is hacked, you can view the password of the hacked account only if you have paid the required amount. The service is using Western Union money transfer for the payments and you have to send the money to Ukraine. Below is a screen shot of the service.

In the website there is a FAQ place, where they say they’ve been doing business for more than 4 years, and provide a link to a Webmoney account that is in fact 4 years old.

I tried opening the page Hacking-Facebook.com in Google Chrome but its said The link appears to be broken. Then I clicked on View cached copy of page from Google and got the page. I am really not sure that if the service is still working because I didn’t try to hack any account because of obvious reasons.
