Actually there are thousands of such apps, I am just introducing some of them to aware not to get trapped by these softwares. (Do not try these softwares at all).
1. First one is getfbhack.com
Their free Facebook hacker program is said to be capable of cracking the password of any Facebook user within a day. Sounds cool, I could try it out, but my Norton Antivirus rejected the file straight away and said it as malware!
2. Second one is s Hack-Fbook-Password, It asks to enter the profile ID of a user and it will crack the password.
It ran certain algorithms to determine the password and finally landed on a page that said you could download the password if we fill an online survey first. It was looking quite real.Those of you who've been redirected to surveys would know they don't work and are put just so to get traffic and earn money.
Setting up websites, maintaining them and developing software is not an easy task and requires a lot of hard work. It requires some money too. So why do these 'hackers' do all the hassle? It's because they get equivalent or more money in return and also many benefits. They can extract your credit card details and other banking info from your system and use it for their advantage. They can hack your account and use it for wrong purposes. Give me one reason why one wouldn't steal money and hack accounts for no loss. ITS THE TRUTH!!
Why do people try to use such unreal hacking procedures? It's because it's unreal to me, it's unreal to you but not to those who are not much familiar with the working of a software. They get in the web of these hackers and eventually get screwed up pretty bad without consent.
The websites give guarantees and also portray their 'imaginary' happy customers so as to trick a reader. Such tactics are simple but really powerful and serves to their advantage in most cases. This is also why there are thousands of such websites available.
