Multi Window Google Talk

One year ago, I posted a trick on Muliti Window Yahoo Messenger. In that post, I described how to open multiple instance of Yahoo messenger on single computer system. In this post, I am going to explain how to create Multi Window Google Talk on signle machine. 

First, download Google Talk and install it. Now, just create a shortcut of Google Talk on desktop with help of right click. Make a right click on the icon of GTalk shortcut then select properties. You will get a new window as same as following. Now, go to shortcut tab of said window and find Target. Where you can see the following Target path of GTalk.

"C:\Program Files\Google\Google Talk\googletalk.exe"

Now, you just need to edit above Target path with few words or just copy following text and paste it in place of above Target line of GTalk shortcut. 

"C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex

Once, you edited GTalk shortcut with above Target line it would be ready for multiple instance. Enjoy !!!

Unwanted Malicious Script

Before few months ago, I got a call regarding Internet trouble. They had troubled opening Internet. They could easily access first page of any website but they couldn't reach second pages or other links of visited website. I checked everywhere and found few viruses and deleted them. But, after then system couldn't let me access Internet. Suddenly, I found installed malicious script on that machine with Yahoo! logo. (Please check following screen shot)


I removed that malicious script from add/remove program options. Restart that machine and it started working normally. They used Yahoo messenger and accept/invite people to share file/web cam. Thus they got said malicious script.

Countermeasures:
(1) Do not accept / invite any one for photo/file sharing or web cam whom you really don't know because it establishes direct connection.
(2) Be careful in Yahoo chat rooms because there are so many fake id users whom will inject any malicious script forcefully via direct connection as per No(1)
(3) Don't click any URL shown in Yahoo chat room's window or your buddy's chat window.
(4) If possible create a fake id for chatting other than your email id.
(5) Always use strong password for security.
(6) Install a good anti virus software and update it on regular basis.

Internet Explorer Trouble

I got a call about troubling Internet Explorer last week. The story is... They have installed Windows XP with Internet Explorer 6. The IE6 troubled them with home page. They modified home page of IE6 from its properties and tried to open its home page. It reached that modified home page first time. But when they closed IE6 and open same home page again it couldn't reach whatever they wanted because installed virus/worm modified IE6 properties forcefully and replaced its home page with "http://www.baidu.com/index.php?tn=dsgj_cb". It is a Chinese website. I tried to modify this home page from Registry Editor but it couldn't work. I worked hard to find .vbs scripting/.reg file which caused to modify home page every time. But I was not lucky to find them. Suddenly I found that installed AVG Antivirus wasn't update since long. So, first I started updating AVG Antivirus while I found some malicious software. Then I scanned entire system with updated AVG Antivirus. I rebooted said system then changed home page of Internet Explorer and it worked. After then home page didn't change automatically like it did before. So, be careful and always update your Antivirus on regular basis.

Internet Options - Enable/Disable

Suppose you work at a place where you share your computer with others. They don't know much more about computer /Internet and every time they change IE's Internet settings which is best for in use. You can stop anyone to alter Internet settings by disable Internet Options under Tools menu. It is quite easy trick. As usual, you just need modify Registry.

Internet Options - Disable:
Type following text in notepad or copy-paste it and run/merge it. It will Disable Internet Options.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions]
"NoBrowserOptions"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Restrictions]
"NoBrowserOptions"=dword:00000001

>>> Download IE Disable Registry File here <<<

Internet Options - Enable:

PHISHING - Never Danger Before

When you want to catch fish, you fool fish and hunt them easily by hooking, trapping etc. Like this you can 'fish'(fool) people on internet with help of 'Phishing'(fishing). The 'Phishing' word is based on 'fishing'. In fishing, you hunt fish and in Phishing you hunt people's mind, steal their important data through identity theft/social engineering.

Definition - Phishing:
(1) It is the act of tricking someone into giving them confidential information or tricking them into doing something that they normally wouldn't do.
(2) It is a form of fraud that aims to steal valuable information such as, Bank account details, Credit card details, User IDs and Passwords, etc.

How does it work - Phishing:
Suppose, I am an attacker and I need your Bank account details such as ID and Password for profit/benefits. So, I will try to use Phishing attack out of few more.
I will create fake login page which looks exact like your Bank's login screen. Then, I will upload it on a server and send its link to you via email. So, when you will open your inbox, you will get link of fake login page. You will click on that link and input your ID and Passwords as normally you always enter on your real Bank's login page. In this case, your details will come to me instead of your real Bank because of Phishing. Please check 2 different login pages of Google Mail. (Maybe one is fake!!)



Target - Phishing:
(1) Banks
(2) Online shopping sites
(3) Well-known Email sites

Medium - Phishing:
(1) Email
(2) Messenger

Countermeasure against Phishing:
(1) Never click the links provided in email messages.
(2) Always type Real URL (Unique Resource Locater) in address bar of your browser.
(3) To read emails in plain text prevents some Phishing attacks.
(4) Never click any link in any messenger window.
(5) If you find any doubtful link in your mailbox then instantly 'Delete' it to prevent accidental accessing that link.

Foolproof Countermeasure:
Few banks recently introduced small device named "Security Device". My favorite secured bank website is "HSBC Bank - The World's Local Bank". They introduce "The Security Device" (Shown in following image). This device has unique number, it registered and mapped with your ID and Password. It has a small button on it. When you press that button it will display 6 digit number and it wont remain same next time. So, when you enter HSBC account ID on its login page then they will ask Password along with 6 digit Security Device number which displays on its small screen. Suppose, anyone steal your ID and Password after then he/she will NOT able to login to your HSBC account without having this Security Device. Thus makes HSBC banking even more safer than other Banks.

Internet Explorer vs. Firefox

I bypassed a well-known filtering mechanism and gained access blocked website. I used easy trick but I got one cool solution that what I have wanted to publish here. It is Internet Explorer 7 related too. IE7 is captured biggest market share due to its look and features. You can install too but before it just check following comparison.



That said filtering mechanism installed on a proxy server. It requires authentication every time when you access outside web. I used Mozilla Firefox to bypass it and gain illegal access of blocked website. But, I faced a problem with Java content web page. This trick didn't work with Java content web page. I installed Vista-aero theme on Firefox which helped me to see Java content web page easily and gave me a brand new Idea!!

So, if you like tabbed browsing and don't want to go with Internet Explorer 7 then just download MSN Tool bar and enjoy tabbed browsing in old version of IE. OR, just download Mozilla Firefox, install Vista-aero theme and get best experience of browsing which you never had before. Check real scree shot of Mozilla Firefox with vista-aero theme.

Change Caption of Internet Explorer

Some cyber cafes or companies use this kind of settings/trick like "Microsoft Internet Explorer by {company name}" or anything whatever they want to display on Internet Explorer's Title Bar. You can also change Caption of Internet Explorer. From this trick, you can create your own caption of Internet Explorer as per following simple steps.

Default Caption:

Change Caption:
You just need to add a String Value named "Window Title"(without quotation) under following registry branches;

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main

After creating "Window Title" string, type whatever you want to display as its value.

OR

Open notepad and copy-paste following text then save it as .reg extension. After then, simply run/merge it.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"Window Title"="Microsoft Internet Explorer by ASHISH JANSARI"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main]
"Window Title"="Microsoft Internet Explorer by ASHISH JANSARI"

Note: Please don't forget to replace text as per your caption in place of "Microsoft Internet Explorer by ASHISH JANSARI".

Proxy Servers

A Proxy server is a computer system or an application program which services the request of its clients by forwarding requests to other servers. The Proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client.

OR

A mechanism which spoof or hide your identity on Internet is called Proxy.

Types of Proxy Servers:

• Anonymous Proxy

A proxy server that removes identifying information from the client's requests for the purpose of anonymity is called an anonymizing proxy server or anonymizer.

• Caching Proxy

A proxy server that stores the documents that it retrieves from other servers in a local cache.

• Web Proxy

Proxies that focus on Internet traffic are called web proxies. Many web proxies attempt to block some web content.

• Hostile Proxy

Proxies can also be installed by online criminals, in order to eavesdrop upon the dataflow between the client machine and the web.

• Transparent Proxy

A Proxy that does not modify the request or response beyond what is required for proxy authentication and identification.

• Non-Transparent Proxy

A Proxy that modifies the request or response in order to provide some added service to the user agent, such as group annotation services, media type transformation, protocol reduction, or anonymity filtering.
