Re: Ransomware on the rise
@Dr.T: One anti-ransomware strategy (other than ad-blockers and disabling Flash, as I alluded to in an earlier comment) is virtualization.  Get ransomware?  No problem if you're running a virtualized instance that can be safely killed!

In fact, researchers are seeing more modern ransomware in the wild that is programmed to detect virtualized instances running -- and will decline to install if it so detects one.  The reason?  Other than the fact that it could be easily defeated, installing on a virtualized instance would allow it to be poked and prodded safely for reverse engineering.

Effective DMARC, DNSSEC, and User training Controls to avoid Phishing and hence Ransomware
I am not very surprised how ransomware like LOCKY and others are spreading so fast. Even after years, most of the organizations have not paid attention to DMARC, DNSSEC, and User traning on Phishing, Vishing, Smishing. Email providers like gmail have spent whole lot in imlplementing DMARC, but most corprate email are not doing much in this field. It definitely is one of the techniques to reduce phishing.

Re: Success and Ease of Execution
 "... Although it can be protected against, even beyond backups. ..."

Backups is always good. For me one of the easiest ways to protect from encryptions is to have higher level of privilege to encrypt specific folders. At least regular users would not be trapped into this.

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

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.

"... For some, the solution has been ransomware. ..."

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. :--))

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. :--))

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

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.

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.
