Increasing Scare
tactics causing Ransom payouts
There has been a shown increase in
a new form of malware called ransomware and scareware; these are payloads that
come in either by downloaded rouge files or a network exploit. The main feature
that the user gets is as soon as the exploit is triggered your computer gets
locked out from user input and a splash screen pops up stating that you have
broken a law and the, FBI, CIA or other police enforcement has been notified.
The next thing that happens is it will usually give the user the option to pay
a fee to unlock the computer. Below is an example of this:
As you can see here it is a very
legitimate looking warning, the graphics are correct, the wording seems good,
and the fine seems within what would seem reasonable. But don’t be fooled by
the exactitude of the graphics and wording, for years spammers and scammers
have been able to make their work seem legitimate, and at times more so then,
the real thing. The main thing to
remember is that these are ‘fake’ and with a good computer technician on call
they can remove these within hours and with any luck not one of your files
compromised.
This is a growing concern, as
Symantec stated in an article at the end of 2012, it has identified over 16
different version of these, and the criminals have stolen more than five
million dollars a year from unsuspecting victims. We have noticed ourselves a
growth in the attack level since then and only expect it grow with some
regularity in the coming year. Also, a new form of these are out that encrypts
you hard drive.
So what do you do when you get this
kind of attack?
1.
Don’t panic, stay calm
2.
Turn off the computer and/or disconnect it from
the network
3.
Call your computer repair provider and they will
be ready and willing help you through this attack.
