how to remove FREE MOBILE RECHARGE virus in orkut

REMOVE FREE MOBILE RECHARGE VIRUS in orkut:

This article has the reference to the previous post ORKUT SECURITY TIPS. In the previous article I warned everyone not to run script (Javascripts) in the browsers (In which you opened orkut account) address bar. But still most of our best buddies have done it successfully ;-)

So I need to write this post for them. Try to follow these steps and never execute or run any scripts in the browser window (whatever may be the situation). This even some times deletes your account. In most worst cases the hacker may mis use your account details for illegal purposes (black mailing, sending adult content to your friends in your account)

▪ What we the users can do to stop this ?


→ Report the URLs at http://www.google.com/safebrowsing/report_phish/

→ Stop script (running javascripts in Orkut).

→ Tell freinds about these scams and to be safe.

→ Delete the auto-generated scam thread in the communities.



▪ What happens when the script runs ?


→ Edit your about me, status and even picture.

→ Send scraps to your friends to run the script.

→ Post threads on the communities you joined.

→ Comment on photos of your friends

→ Send testimonials etc.



▪ I have already run the script. Now what can i do ?


→ Clear cookies and Cache

→ Change your account settings ie, password & security question.

→ Edit your about me, status etc which was changed by the script.

→ Never run any type of scripts again.

Ten most commonly used internet passwords

 A data security firm has unveiled the ten most commonly used passwords on the web.

To reach the conclusion, Imperva analysed around 32 million passwords that had been exposed in a recent hack of the RockYou website.

Last year a hacker had breached the site’s company database, gaining access to the unencrypted usernames and passwords of all its 32 million users.

Now, after studying the breach the firm has come up with a list of the most commonly used passwords which website users should avoid, reports The Telegraph.

“Everyone needs to understand what the combination of poor passwords means in today’s world of automated cyber attacks: with only minimal effort, a hacker can gain access to one new account every second-or 1000 accounts every 17 minutes,” said Amichai Shulman, Imperva’s chief technical officer.

“Employees using the same passwords on Facebook that they use in the workplace bring the possibility of compromising enterprise systems with insecure passwords, especially if they are using easy to crack passwords like ‘123456’,” he added.

“The problem has changed very little over the past 20 years. It’s time for everyone to take password security seriously; it’s an important first step in data security,” he said.

The ten most commonly used passwords analysed in the study were:

1. 123456

2. 12345

3. 123456789

4. Password

5. iloveyou

6. princess

7. rockyou

8. 1234567

9. 12345678

10. abc123.

Clipboard Hack Problem Internet Explorer Security Tip

Clipboard Hack Problem - Shocking news about CTRL+C:  View Demo

CTRL + C is the most useful action that we use everyday. But, I have found this to be very dangerous with internet explorer and netscape navigator. Because, your clipboard text (which you have copied by pressing CTRL+C on your system) can be easily retrieved by the websites, if they really wish to do so.

Imagine a scenario, when you tried to copy your account number or password or any other personal information on your system, it will be saved (or copied) into the clipboard (temperory buffer in your operating system). Then if you open the website (one who intentionally try to access your personal information, i.e. the hackers) knowingly or unknowingly. Thats is it, they are done with their work. You need not do anything on your own. Your information is copied and they can access the information from the clipboard and use it for illegal activities.

So be very careful my dear friends. This will work in internet explorer and netscape navigator only. This is not possible with google chrome,mozilla firefox or any other browser. Remeber, today the most used browser around the world is internet explorer. So just avoid these kind of attacks and be on safe side.

Follow the steps below to safeguard yourself from clipboard hack:

1. GoTo internet option --> Security
2. Press custom level
3. Under allow paste operations via script, Select "Disable" radio button

 Your are done with the security setup. Now, your browsing is safe than before. Enjoy the browing

Orkut security tips: Secure your orkut account

Due to orkut's open nature, users can unwillingly infect their computers with viruses, spyware, adware, and other unwanted junk. This can result in strange behavior, such as sending unintended scraps to friends that may even infect more viruses. To help prevent this from happening, I recommend the following safe practices:

    * Don't click on any link (e.g., free recharge coupon kind of) you suspect to be malicious, even if sent by someone you really trust.
    * Never select the "remember me" option when you're using a public or shared computer.
    * Scan your computer regularly for viruses, spyware and adware.
    * Never run any script while logged into orkut, no matter what it claims to do. Usually you will be asked to copy and paste a code in your web browser, remember to never do so!
    * Always check your browser's address bar to make sure you enter your sign-in information only on www.orkut.com and other Google properties.
    * Change your password regularly and keep it secret.

Additionally, orkut or google will never send you spam emails asking you to download anything or to send them personal information, such as your password or bank account information. Orkut is a free service, and it will remain safe with your help.

Comparing Two Images in C#

Comparing Two Images in C#

I’ve recently been doing a bit of work generating images, I have also need to compare the images that I generate with an image that has already exists.
I found a number of web sites that suggested the following way of comparing two images, by cycling through each pixel in an image and returning false if there is a mismatch in the pixels.

*A quick brain tickler**…*

Please look at the math below:
They say only people with an IQ with 120 and over are able to figure this
out.

If:
2 + 3 = 10    = 2
7 + 2 = 63    = 7
6 + 5 = 66    = 6
8 + 4 = 96    = 8

Then:
ch
9 + 7 =  ????

The number you find out is the password to open the attachment.
Sign your name, save it, and forward it, replacing the original

Working with Delegates in C#

Abstract In this article I'll discuss what delegates are with lucid code examples. Introduction

Delegates in C# are like functions pointers in C/C++. A multi cast delegate can refer to several methods. A delegate can be used to invoke a method, the call to which can only be resolved or determined at runtime. This article discusses what delegates are and how they can be used in C# with lucid code examples.

Understanding Connection Pooling in .NET

Abstract
Connection Pooling can increase the database performance to a huge extent. This article discusses what Connection Pooling actually is, how it can boost the performance of database access and how we can create a Connection Pool in .NET and add and remove connections to it.

Introduction

Connecting to the database is resource intensive and a relatively slow operation in an application but the most crucial of them all. A Connection Pool is a container of open and reusable connections. A Connection Pool is released from the memory when the last connection to the database is closed. The basic advantage of using Connection Pooling is an improvement of performance and scalability while the main disadvantage is that one or more database connections, even if they are currently not being used, are kept open. The Data Providers in ADO.NET have Connection Pooling turned on by default; if you need to turn it off, specify Pooling = false in the connection string being used. Connection Pooling gives you an idle, open, reusable connection instead of opening a new one every time a connection request to the database is made. When the connection is closed or disposed, it is returned to the pool and remains idle until a request for a new connection comes in. If we use Connection Pooling efficiently, opening and closing of connections to the database becomes less resource expensive. This article discusses what Connection Pooling is all about and how Connection Pooling can be used efficiently to boost the performance and scalability of applications.
