A Very Basic Guide To SSH Tunnelling To Bypass Web Filters

SSh, Secure Shell, is a program and protocol for securely logging in to and running programs on remote machines across a network, with encryption to protect the transferred information and authentication to ensure that the remote machine is the one desired; To use ssh to connect to a remote computer. In this tutorial, I'll show you how to do simple ssh tunnelling to bypass web filters.

We'll be using a ssh client in this tutorial. One such SSh client is putty and we be using putty in our tutorial. It can be downloaded from HERE. We need a working SSh account and there are lots of free as well as paid free shell providers. I'll be using one of the shell accounts for this tutorial.

After downloading putty, open the program and enter the host and port information. The screenshot below will be helpful for you.


Now go to the SSh option below in the left menu of Putty. And select the tunnels submenu. Set the source port to any higher ports. I chose 8080 in my example. Then select the dynamic option. And click on Add by leaving other options as they are.


Now, click on Open and login to your SSh server. The only thing left now is to setup your favourite browser to work with the SSh tunnel. In firefox(under ubuntu), I go to Edit - Preferences - Advanced - Network - Settings to set the proper proxy configuration. The setup entry will be:

Socks host: localhost
Port: 8080

That's all for setup. Now you can use the ssh tunnel to browse webspace by bypassing web filters in your school or office. I hope it was useful. Thanks. :)

How To Steal Various Keylogger's Log

Keylogger is a device or program that captures activities from an input device. Malicious people can make use of keyloggers to capture personal information being input into a computer system. Many of these keyloggers have the feature of uploading the log to some pre-defined(set by hackers) FTP servers. We can exploit this feature of keyloggers with the help of our Big Daddy, Google to obtain the logs of these keyloggers.

There are numerous keyloggers out there in the market and they provide this useful feature of FTP uploading of logs. But, the google is so powerful that it also indexes these log files. We can use the texts that are generally used by keyloggers to write in the text file. For example, following is the format of how iStealer, one of the widely used stealer, records the log through FTP.

Program: Firefox
Url/Host: http://www.google.com
Login: xxxxx
Password: xxxxx
Computer: samar-pc
Date: 2011-04-23 01:33:03
Ip: 116.90.*.*

So, we can use the terms such as Program, Url/Host, Login, etc. as the search keywords. The following search phrase would then reveal the iStealer's log.

Program: Url/Host: Login: Password: Computer: Date: Ip:

You can creatively specify the particular hosts or programs of which you want the login information. Moreover, you might also want to use the Date feature of advanced google search to find the latest results as they will have more likelyhood to work.

Another log format of some other keylogger is something like below so you can figure out the possible dork for this format.

APPLICATION : Firefox 4.0
URL : https://www.facebook.com
USERNAME : samar
PASSWORD : 144334@&%

You can actually experiment on your own to create new useful dorks. Many times, you will find good stuffs using these dorks. Just be creative with what you look for. I hope this guides you a little. :)

Enable Network Play Without Lag/Freezes In Counter Strike [How To]

Recently I had posted about how to have counter strike 1.6 run under linux but today when I was just testing to see how well the network play works, I found that the game freezes after connecting to the CT server. I searched on google and found a perfect solution for it.

I've tested this on the installation of Counter Strike : Condition Zero but should also work in Counter Strike 1.6.

The motd.txt file in the cstrike and czero can not be rendered properly by WINE so the game freezes. To solve this problem, we remove the motd.txt file and then, we create a new read only file with the name motd_temp.html which should be empty and there should be no problem rendering this new file as its just an empty file.




If there already exists the motd_temp.html in those directories, be sure to delete them and create a new empty file. To change the permission to read only, you can use the chmod command as below:

chmod +r-wx motd_temp.html

Now, you can play the counter strike in lan or with any server without any lag or freezes. Happy gaming. :)

How To Steal Stored Passwords From Firefox

Many of us use the Firefox's built-in password manager to remember and store the password of the sites we login to frequently. While this can be very useful feature, it can be exploited by anyone with physical(or any other form of access to the filesystem) access to know the saved passwords of the user. In this post, I will discuss how you can view and save the stored passwords of your friends for future reference.

When we select "Remember Me" option to store passwords, the passwords are stored in two files.
1.key3.db
2. signons.sqlite

These two files are in the profile directory of the mozilla firefox application data for the respective user. Profile folders are placed in a common location by default but are named randomly for additional security (e.g., "xxxxxxxx.default" is the profile folder name for the "default" profile, where xxxxxxxx represents a random strung of characters). This directory is available at different places according to the distribution.

Under windows: %APPDATA%\Mozilla\Firefox\Profiles folder will list the profiles and you can open any of the profiles from there.

Under linux: ~/.mozilla/firefox/xxxxxxxx.default folder is the profile folder. So you can navigate to ~/.mozilla/firefox/ to view the profiles.

Under MAC: ~/Library/Mozilla/Firefox/Profiles/ or ~/Library/Application Support/Firefox/Profiles/ are the folders containing the profile directories.

You can follow any of the following two methods to view the stored passwords:

Method 1: In the target computer, go to Edit->Preferences->Security and click on Saved Passwords and then click on Show Passwords to view the login details of the victim in linux. In windows, you will have to go to Tools->Options->Security.

Method 2: The first method would be applicable only for viewing the login details in victim PC. Whenever you want to save these details for further reference, you will have to copy the previously mentioned two files and save to your USB drive(or maybe in mailbox). Now, all you have to do is copy these two files to the profile directory of your PC and then go to the menus mentioned in method #1.

I hope this was useful. Thanks. :)

gufw - A Graphical User Interface To Manage UFW Firewall

Gufw is an easy to use Ubuntu / Linux firewall, powered by ufw.

Gufw is an easy, intuitive, way to manage your Linux firewall. It supports common tasks such as allowing or blocking pre-configured, common p2p, or individual ports port(s), and many others! Gufw is powered by ufw , runs on Ubuntu, and anywhere else Python, GTK, and Ufw are available. Iptables is already a very powerful tool by itself, but it's syntax can get awkward at times and hard to figure out, so Ubuntu developers decided to make ufw ("The reason ufw was developed is that we wanted to create a server-level firewalling utility that was a little bit more for `human beings`"), which was to be simpler. Now, on the graphical side of things, Firestarer already existed. But why not make an even easier to use GUI for desktop `human beings`, powered by ufw? This is where Gufw comes in.

To install Gufw in ubuntu, type the following in your terminal:

sudo apt-get install gufw

You can run Gufw in GNOME menu: /System/Administration/Firewall configuration. To know more about gufw and ufw, you can check the manpage with man gufw and man ufw.

Counter Strike 1.6 Under Ubuntu Using WINE [How To]

WINE is a very useful software that helps you run windows applications in linux, BSD and MAC OS. If you have just switched to ubuntu and can't find any interesting games like counterstrike for linux then you don't have to worry. The WINE will help you play the games like counter-strike under your ubuntu linux.

First of all, install WINE and in this tutorial, I assume that you've installed the WINE. Now, change the permission of your counter-strike 1.6 executable's permission by issuing the command chmod +x Counter-Strike1.6.exe

After finishing the installation, the shortcut icons will be created in your desktop and you might need to edit the shortcut for fully working counter strike installation. Otherwise, the game will just freeze in a window. To edit the shortcut, open the Counter-Strike 1.6.desktop file with gedit and replace all the contents with the content below:

[Desktop Entry]
Name=Counter-Strike 1.6
Exec=env WINEPREFIX="/home/samar/.wine" wine hl.exe -game C:\\\\Program\\ Files\\\\Counter-Strike\\ 1.6\\\\cstrike.exe -gl -gldrv Default -w 800 -h 600
Type=Application
StartupNotify=true
Path=/home/samar/.wine/dosdevices/c:/Program Files/Counter-Strike 1.6
Icon=BBDA_cstrike.0




Also, be sure to edit this file according to your home folder. You'll have to replace samar with your home folder name in the above content.

Now, you are ready to go. The game will play well without any noticiable errors. Have fun. :)
