Here is something worth knowing if you have a mobile phone.

Have you ever wondered why phone companies don’t seem interested in trying to prevent the theft of mobile phones? If you have ever lost, or had one stolen, and if you are on a plan, you still have to pay the plan approximately up to 24 months, and you have to buy another handset and/or enter into another contract. This is more revenue for the phone company. There is a simple way of making lost or stolen mobiles useless to thieves and the phone companies know about it, but keep it quiet.

To check your mobile phone’s serial number, key in the following on your phone:

star-pound-zero-six-pound ( * # 0 6 # ) and a fifteen digit code will appear on the screen.

This is unique to your handset. Write it down and keep it in a safe place. If your mobile phone get stolen, you can phone your service provider and give them this code. They will then be able to block your handset, so even if the thief changes the sim card, your phone will be totally useless.

You probably won’t get your phone back, but at least you know that whoever stole it can’t use/sell it either. If everybody do this, then all the thieves will also come to know that there would be no point in stealing mobile phones as they can’t use/sell those stolen mobile phones. So start it now and spread the news.

Protect your Privacy

Now a days we all use computer and internet. But a very few of us sweep or clean up our computer hard drive or using track which should be done in a regular basis. There are lots of good reasons to clean up your computer’s hard drive and usage tracks. One of the most important reason is:

If a hacker ever gained access to your machine, some of your juiciest information is stored in your Web browsers cache. There is enough in almost every browser on earth to engineer a social breach. In other words a hacker could gain access to your personal data and then use it to pose as you.

Actually it is very difficult to keep all of your private information protected, given that it’s scattered all over your machine in places you’ve never even heard of. Like:

  1. Temporary Internet files, Web site cookies, browser history, and index.dat.
  2. Typed URL history.
  3. Saved passwords and form auto-complete information stored in your browser.
  4. Recent Documents.
  5. Usage history of: Start/Run, Search.
  6. Temporary directories on the hard drive.
  7. Items contained within the Windows Registry.
  8. Deleted items contents.
  9. Media player history.
  10. And many more…

Here’s what you can do about it. First, use one (or more) of the following tools to automatically erase all of the things on the list above. And by the way, all two of these offer Secure File Deletion, which makes the deletions unrecoverable:

  1. CCleaner
  2. Privacy Eraser

So one of these will do the hard work for you. According to me you should do these kind of cleaning very often (At least once in a month if more than that is not possible).

Password is one of the most important things in the Web world. We use password everywhere in this world. So it should be secret so that any body else can’t access my personal account. But sometimes unfortunately it doesn’t remain secret. Sometimes hacker can get my password easily.

If your password is weak and normal and i want to crack that, how many guesses would it take before I got it? Lets see…

If i know you personally i can easily get some common information from you like your close relatives name or pet’s name or something like this. Then I might just be able to get into your e-mail, computer, or online banking. After all, if I get into one I’ll probably get into all of them. These are some commonly used password:

  1. Your wife, child, boy friend/girl friend or pet’s name.
  2. Your mobile/home/ID card number or First/Last 6 digits of those number.
  3. “password”.
  4. 123 or 1234 or 123456.
  5. asd or asdf or asdfgh or asd123 or 123asd.
  6. Date of birth – yours, your partner’s, your child’s or your girl friend’s/boy friend’s.
  7. Name of your favorite Band/Sports team/Singer/Writer.
  8. “love”.
  9. “sex”.
  10. Some slang word.

Believe me that should probably cover almost 50% of the people of this world. But don’t worry. If I didn’t get it yet it will probably only take a few more minutes before I do.

One of the simplest ways to gain access to your information is through the use of a Brute Force Attack. This is accomplished when a hacker uses a specially written piece of software to attempt to log into a site using your credentials. And how fast could this be done? Well, that depends on three main things, the length and complexity of your password, the speed of the hacker’s computer, and the speed of the hacker’s Internet connection.

Now a question may arise into your mind that how would i get your login ID for different sites? The answer is very simple.  All those cookies are simply stored, unencrypted and nicely named, in your Web browser’s cache. (Read my another post named “Protect your Privacy” to remedy this problem).

So if your password is not that hard and if a hacker is dedicated to get that then ultimately he/she will get that. Believe me, I understand the need to choose passwords that are memorable. But if you’re going to do that how about using something that no one is ever going to guess and doesn’t contain any common word or phrase in it.

Here are some password tips:

  1. Randomly substitute numbers for letters that look similar.The letter ‘o’ becomes the number ‘0′, the letter ‘a’ becomes ‘@’. (i.e. – The word ‘password’ becomes ‘p@ssw0rd’).
  2. Randomly throw in capital letters (i.e. – p@sSw0Rd).
  3. Think of something you were attached to when you were younger and no body knows about it, but DON’T CHOOSE A PERSON’S NAME! Every name plus every word in the dictionary will fail under a simple brute force attack.
  4. You really need to have different username / password combinations for everything. Remember, the technique is to break into anything you access just to figure out your standard password, then compromise everything else. This doesn’t work if you don’t use the same password everywhere.
  5. Try to change your important password every now and then. (At least once in a month).

Another thing to keep in mind is that some of the passwords you think matter least actually matter most. For example, some people think that the password to their e-mail box isn’t important because “I don’t get anything sensitive there.” Well, that e-mail box is probably connected to your online banking account. If I can compromise it then I can log into the Bank’s Web site and tell it I’ve forgotten my password to have it e-mailed to me.

I also realize that most people just don’t care about all this until it’s too late and they’ve learned a very hard lesson. But why don’t you do yourself a favor and take a little action to strengthen your passwords today?

Now a days among us whoever uses internet, almost everyone uses facebook. We do lots of thing in facebook. One of those things are upload photo of ourselves and our friends or relatives. In case of the security of a uploaded photo there are 4 kind of privacy settings:

  1. Everyone.
  2. Friends of Friends.
  3. Only Friends.
  4. Customize.

Among these the default settings of facebook is “Friends of Friends”. So normally an unknown person shouldn’t see your uploaded photo. Normally if you search with an unknown person’s name whose photo is not open for everyone then you are not going to see the photo tab in their profile. You will get to see the Info or Wall tab. But here is the hack by using what you can see any unknown person’s uploaded photo even if the setting is only “”Friends of Friends”. You just need to do the following steps.

  1. Login to facebook.
  2. Search that person whose uploaded picture you want to see.
  3. Go to that persons profile page.
  4. Copy the following code and paste it into the browser’s address bar and hit the ENTER key.

javascript:(function(){CSS.removeClass(document.body,%20'profi
le_two_columns');tab_controller.changePage("photos");})()

BOOM!!! Magic!!! All the uploaded photos are in front of you. My purpose of writing about this topic and posting this code is to prove a point, not break into users’ accounts. The point is if you upload your very personal photo and really don’t want unknown people to see it then set the privacy settings “Only Friends” instead of “Friends of Friends”.
