Ransomware on the rise
Alas, as Brian Krebs reports in his book Spam Nation, a lot of this is the side effect of the successful crackdown on pharma spam over the past so several years.  Botnet masters, script kiddies, and other black-hatters needed to come up with new monetization plans.  For some, the solution has been ransomware.

Re: Ransomware on the rise
It's no wonder why the answer has been ransomware for some. It's easy to transport, easy to create, and modular when designed correctly. Ransomware can have varying levels of complexity and has even been packaged with other malware. Due to these parameters you run the gamut from very capable malware writers to even the most inexperienced leveraging it as a malicious medium.

Social Engineering
Social engineering, and from my experience phishing, has been how ransomware has become so prolific. The end user is providing the attacker with keys to the door but who can blame them when phishing attempts are becoming more authentic to look like genuine traffic.

Success and Ease of Execution
Ransomware is very appealing due to its ease of execution. Dropping a package that encrypts files is on the lower level of complexity and it has had a very high rate of success. If an efficient backup process is not in place then you risk losing your files forever. These files may hold sentimental value to people and they are willing to pay to retrieve them.

Re: Success and Ease of Execution
@RyanSepe: Although it can be protected against, even beyond backups.  Modern ransomware often detects for virtualization -- and declines to install if it detects so.  Obviously, if it did install, not only could it be easily defeated (all you'd have to do is kill the instance and you're fine), but also you'd be able to isolate it in a virtual sandbox and then reverse engineer it, threatening the entire business model.

Re: Social Engineering
@RyanSepe: Well, that and Flash.  So much of ransomware could be defeated if people just didn't run Flash.  :/

Ransomware big impact
 

One of the problem with Ransomware it is not easy recovery, if the data is encrypted you have to pay to get it back. In case of a visor you just need to download last definitions to recover. :--))

Exactly agree with this. At one point they need to make money directly over the efforts they put.  This is becoming growing problem, we need to start working on anti-ransomware strategies. :--))

Agree. We have been discussion that social engineering (and reverse social engineering) is a very effective way of executing an attack, obviously nobody listens to it, ransomware is easy a quick way of making money out of it.

Exactly. I just mentioned in the other post. This is like cheating whole system and security. Using security back to against the users.  :--))
