Ransomware evolution continues, CryptXXX rakes in thousands

Over the past couple of years, the age old dominance of adware, spyware and trojans has begun to die off in favour of something new and far more malicious: ransomware. The evolution continues to this day, with the latest version of the CryptXXX ransomware bringing in over £34,000 in the past few weeks.

Ransomware, for the uninitiated, can lock your system and encrypt your files so you can’t recover them. It then often demands payment in Bitcoin to a certain address, sometimes threatening to permanently delete the information if you don’t pay up – either way though, you’re unlikely to get them back.

While sometimes security firms like Kaspersky have been able to discover workarounds that help people recover their files for free, the latest version of the CrypXXX ransomware has fixed up those flaws and has already had massive success.


Most nefariously, the hackers allow you to decrypt one file to show that if you pay up, the tool will work.

So far the Bitcoin address associated with the ransomware has received over 70 bitcoins, worth around £34,000 at the time of writing. The success of this is being put down to an increased awareness of Bitcoin which makes it easier for those affected by this malware to purchase it and send it over to the hijackers.

However the complexity of the malware itself has improved. It now adds an extension to all encrypted files, which makes it difficult to recover them from backups, which has traditionally been the best method to combat ransomware attacks.

It’s still heavily recommended, but as Ars points out, it’s worrisome that it’s proving to be a much less effective way of protecting yourself against ransomware.

KitGuru Says: Malware like this is some of the most malicious. At least it seems to be trending that perpetrators go after companies, which can more easily absorb costs involved.

    Yea I have gotten a few systems in that have had the older versions of this virus on it & have a little bit of luck getting data back but not always. It sucks that no one has caught these guys or at least found a better way to fight these types of viruses. I have a message out there for those that make these viruses if your watching sites like this. Just think of how much money you could make if you actually went out & got a job that put your so called skills towards something good and make an honest days pay and maybe feel good about yourself in doing so. I know it most likely makes you feel special that you can frack up someones data like this but it is not just the big companies that are losing their data it is the common user and a lot of the time all you succeeded in doing is making them lose their kids baby picture’s and a slew of other stuff as well and most times they can not afford to pay the big price you demand or even know how to get a bitcoin so you and the poor mom both lose. Just saying

    simply keep a unconnected backup HD, I don’t keep any docs on my computer its the basic OS and then everything get stored to external HD and if I don’t need to access those files its not connected, as far as corporations getting ripped off, well all I can say is “how does it feels?”. You’ve been ripping off your consumers for decades now and exploiting your workers which are the only reason your companies are in existence. Your going to find that the masses do not need a elite class to rule them and we can run our own companies just fine.

    IMO these people are currently employed by intelligence agencies to spread this junk as reason to strip away your online freedoms once they have taken all your person ones….

    Only come across ransomware once on a client’s PC and luckily it was quite an old version that didn’t encrypt files. Just had to boot the PC into safe mode and run Hitman Pro to get rid of it.

    If this happened to me I’d just flatten my machine and call it a day. Anything super important to me is in the cloud and in my Linux server.
