Where does Cryptxxx Ransomware come from?

Our researchers at say that such malware could be found on malicious web pages. At this point, it is advisable to acquire a legitimate antimalware tool and scan your system with it. To ensure your computer's security, it is important to delete not only the ransomware but also other possible threats.

How does Cryptxxx Ransomware work?

Cryptxxx Ransomware is different from other similar infections because it does not use executable files. The malware creates a random CLSID folder in the %TEMP% directory and places a DLL file, which is launched by a legitimate system file called rundll32.exe. It happens because this infection modifies the legitimate file and names it as svchost.exe. Then it encrypts documents, pictures, video files, and other similar data. Lastly, it shows you a warning pop-up with the instructions from the malicious application’s creators.

The instructions explain that your data was locked with an encryption method called RSA. The malicious program’s originator created public and private keys that are 4096 bits long. Keys of such length are thought to be unbreakable, and that is stressed in the instructions. Also, it says that you are given a unique personal ID, e.g. 5AE45DC7E2AD. All the files and folders created by this infection should also be named after the unique ID number. Furthermore, Cryptxxx Ransomware gives you an opportunity to unlock your data if you are willing to pay the ransom. The instructions rush users to make the payment in bitcoins and provide a link (e.g. to more detailed instructions. If you want to load it, you have to get the Tor browser. The files that were encrypted may be priceless to you, and you might think about paying the ransom, but it is better not to make rash decisions. No one can guarantee you that you will get the keys needed for the decryption after you transfer the money, so it should be your last resort.

How to delete Cryptxxx Ransomware?

If you follow the removal instructions below you will see that we listed all locations for you. The most complicated part should be the deletion of the DLL file as it is placed in a random CLSID folder created by the infection.
