Beware of Auto-Liker's

Last week, One of my friend raised a question. Is it possible to increase the no.of Likes to his Photo on a Facebook page. I wonder how do they think like this???
Between, there is no such thing called auto liker. And Facebook doesn't allow third party codes to access their database.

He also added that he saw some friends saying about this auto liker thing.So I just asked my friend who knows everything in the world, "Mr.Google" . He suggested me some results for my search.

I was shocked to see many websites claiming that they can increase the likes of a picture or status in Facebook. I wonder how is that even possible????... Crazy right?

But I was curious about what these websites are up-to. So I just asked my friend to log into her Facebook Account and access one of the auto liker website. She did and we read the steps, which were mentioned to do in their Homepage. And they asked us something called access token from our profile. So we just clicked a
link saying "Click here to get Access token".

That link Redirected us to many links. Since I have installed ad-block plus in my Chrome browser I wasn't able to see those sites. At-last it took us to her account's access page.

OMG!! I wonder what would have happened if dint read those permissions. Her profile would have been HACKED!!... Luckily my crazy mind just captured those things.

Then I deeply studied about this thing and came to know that, its a trick to know about an individual and get access to their account. This type of Hacking is called as Self-XSS

What is Self-XSS?

Self-XSS, or a cross-site scripting scam, is designed to trick you into giving away access to your Facebook account. If a scammer gets access to your account, they can post and comment on things on your behalf.

Scammers who use Self-XSS usually trick you by promising to help you hack somebody else's account. The scammer's goal is to get you to run their malicious code on your computer. When you run their code, you grant the scammer access to your account for fraud, spam, and tricking more people into running the scam.

The scammers will usually target your friends by posting on your Timeline.

To avoid Self-XSS attacks, never copy and paste suspicious links

Converting Binary to Text (ASCII)

In last post, we saw about how binary works and how it is converted to decimal. In this post we will see about how these binary codes are converted into text by the computer.

ASCII - American Standard Code for Information Interchange.

ASCII is essentially the letters, numbers and symbols that are stored in our computers through the use of fonts.When the keyboard relays the buttons you pressed, it sends in a code which is then converted to the ASCII equivalent.

For example:

Here is a HIDDEN message in the form of Binary Code.

0100100001100101011011000110110001101111
 Lets split this up into 8 bit codes.

01001000  01100101  01101100  01101100  01101111

Now find the  decimal values for these codes.

01001000 = 72
01100101 = 101
01101100 = 108
01101100 = 108
01101111 = 111

Here comes the concept of ASCII .There is something called ASCII tables.
It contains alphabets,numbers and symbols. Each of them essentially corresponding to the related values.

For the computer it is programmed into them. For us the computer provides a short-cut to identify the ASCII code.

By pressing ALT + [The Number], you will get the ASCII equivalent of that number. 


For example, by pressing the ALT key and then the numbers 72 in any text editor, you will get the corresponding “H” to show up.

so lets try for all the numbers,

72 = H
101 = e
108 = l
108 = l
111 = o

So the entire HIDDEN message is translated to TEXT.

Binary to Decimal - Concept

                                                 We all have seen binary codes. Collection of  0's and 1's in a long string are called as Binary codes. For example: 0001101110010101000011101. But these 0's and 1's also represents Decimal numbers. Computers use binary codes and not decimals, first we will see how binary and decimal are related together.

BINARY SYSTEMS:

Lets us consider some empty slots.      _ _ _ _ _

Binary codes should be read from Right to Left. It cant be changed.

First slot from Right represents value of 1, Second is value of 2, Third is value of 4, Fourth is value of 8, and the cycle continues by multiples of 2.

CONDITION:
1 means 'YES', 0 means 'NO'

For example: Putting 1 in the first slot (from right-left) and 0's in the remaining represents the value 1 (one).
                     00001 = 1
                     Putting 1 in second slot and 0's in remaining represents the value 2.
                     00010 = 2

If we want to represent the number 8 in decimal, for binary...
Remember the condition.

NO  YES  NO  NO  NO
(0)    (1)    (0)    (0)    (0)


01000 = 1000 = 8

If you got 1's in two or three places, just add the values of 1's.
0101 = value of 1 in first slot is 1, and value of third slot is 4. add it up gives the value.
0101 = 5

 NOTE: For mastering in Binary ,... just practice yourselves.

How to HIDE a folder manually

• Right-Click on the folder which you want to hide and select 'Rename'.
• When you rename, it hold down "Alt" and press "0160" and enter.
• This will create an invisible space, so it will appear as if it has no name.
• Now your folder name is hidden. Next is to hide the folder's icon.
• For this, right click the folder and select "Properties", select the tab "customize" and select "change icon".
• Scroll along and you should see a few blank spaces click anyone of that and click OK.
• Now your folder is invisible.

NOTE:

          For better hiding, manage the folder to bring last in the list. you can do this by changing the type of 'sort by'.
