Interesting to read that there is no real decryption, just the use of backup and other solutions to recover files !

I think there is a real decryption if you pay the ransom. But if you don't pay the ransom, you don't get the encryption key and therefore you can't really decrypt anything. So you have to restore from backups.

Yes, that's what I meant, I like for instance the trick that consists in using Windows System Restore features to recover previous versions of files. Provided SR is activated and running...

Many of the ransomware variants actively destroy/encrypt any backups they can find - and they look - so this isn't a magic bullet of any kind. You would need a backup that was offline at the time of the infection for this to be a complete solution.

Although a bit far fetched for some...but I have no trouble imagining data stored in your cloud solution could be affected by such a virus/malware too, especially when you use the syncing capabilities provided by your cloud solution.

As Stoic Joker said...there is no substitute for an offline backup (at the time of infection).

I have the paid version of cryptoprevent; "CryptoPrevent is an Anti-Virus/Security Software Supplement, originally designed to prevent infection from the CryptoLocker threat which emerged in late 2013. Since that time, CryptoPrevent has grown into a robust solution, providing protection against a wide range of ransomware and other malware.

CryptoPrevent doesn’t stop there.  We are continuing development efforts to expand the software into something more than just a ‘security’ solution."

Me too. Family pack, on everyone's PC.

That said I've installed the free version on a number of, shall we say, "historically proven at risk users", thinking that any help at all these types can get is good. :-)

Interesting. I tried (and paid for!) WinAntiRansom, but am completely underwhelmed by it - since it only protects a single directory tree, it's not very useful for how I use my system. But I can't find any real info on CryptoPrevent to determine if it would be any better. Anybody have a link to more details?

I also have a hard time understanding how the product works or exactly what it does from reading the website.

The basics of what it does is prevent things from running from strange places - like temp folders, etc - and also prevents some sensitive utilities (like vssadmin that could delete all your shadow copies) from running. The pay-for add-on is I think a signature service but I'm not completely clear on exactly what it does - it likely has known-good and known-bad lists. In an enterprise you could do a lot of this with group policy and file server management tools, but CryptoPrevent is more flexible and quick to manage if need be, and it works fine on non-domain-joined computers.

I love how people try to circumvent their own stupidity ("oh, a file attachment / a suddenly visible link / ..., I must open it!") with software. What could go wrong?
Obviously, stupidity makes a good market.

Sometimes it comes in the lovely package of drive-by exploits.
Sometimes it comes in tailor-made spear-phishing campaigns.

Often, you talk out of your ass.

In this case, I'm positive that it's disgusting.
