Facebook rogue applications still lurking around

For quite some time now there are rogue applications  trying to convince you that you are able to check whoever viewed your profile. There are a lot of different names for this rogue application, some but not all include:

• creep exterminators
• catch them being creepy
• creepy profile peekers
• privacy bros
• we catch stalkers

So what will this fake application do? For starters, it will surely NOT show you who's been viewing your profile.  If you land on this application, you will be presented with the following screen:

Request for permission

You then have to allow access from the application so they can show you who's been lurking around your profile. But wait ! You first have to complete a survey and then you are able to check it out. Simple, right?

Facebook verification

Not exactly. These fake surveys are pretty common on the internet. It is a typical scam. For example, I had one particular survey that urged me to download SmileyCentral, the other tried to deliver me Webfetti.

• ff8d221113615909b07b1ba9ceb8466a (SmileyCentralPFSetup2.3.78.2.NoSA.NoHP.ZNfox000.exe)

Another fake survey wanted me to fill in my phone number, and afterwards send an (expensive) text message to 'unlock' the application. In addition to letting you fall into one of these scams, the rogue application also promotes itself on all of your friends’ walls:
