I wanted to post something about Ransom-Ware on smart phones like iPhone and Android, but I decided to post small post on what this means then latter I will discuss those ransom ware on phones.
Anyway, some of you may have heard of "Bit-locker" coming with "Bit-coins" and later heard of "Crypto-locker" all are same analogy of a malware. What it does is simply installs itself on your PC machine and then runs an encryption algorithm
An Encryption Algorithm is a set of mathematical equations that you input a stream of data and a key then those 2 inputs are passed through the algorithm. The output data is different from the input thus providing confidentiality of data, so that the right parties use this key or so to decrypt the data to it's original data. Of course there are variations of this idea but you get its basic.
Now after running the algorithm it produces a unique key and sends it to the attacker, now this attacker holds your encrypted data or hard disk ransom till you pay a certain amount of money so that the attacker can send you the key for you to decrypt your data.
Up till now there was no much luck in breaking or reversing those malware since there is a lot of variations to them. Even worse it already came to mobile phones.
So what we need to do is please don't click on random links specially if they are suspicious, or coming from unknown senders to your mail. And please take care where you download your applications and software
