It must be a big trouble to get infected by ransomware, since ransomware can stop you from using your PC or accessing your important data until you pay for “ransom”. There are different variants of ransomware which generally can be divided into two categories: the Crypto ransomware and non-Crypto ransomware. Usually, the former encrypts your important data, while the latter locks your computer. But they have one thing in common – demand you to pay a “ransom” to regain access to your computer or data.

In this article, we are going to talk about a Crypto ransomware called CryptXXX. If your computer has been unforunately infected by this ransomware and you are looking for guides to remove this threat from your PC, then you can continue reading.

Threat Details

Name CryptXXX
Category Crypto Ransomware
Threat Level High
First Released in April, 2016
Latest Version CryptXXX 3.0
Spreading Ways Spam emails; Exploit kits
Target OS Types Windows XP, Windows7, WindowsVista, Windows 8, Windows 10
Main Behaviors Encrypt files; Display ransom note

CryptXXX is another strain of ransomware which was first found by ProofPoint in the middle of Apirl 2016. Security experts say this ransomware spreads via web pages that host the Angler exploit kit which takes advantage of vulnerabilities to push the Bedep click-fraud malware on the users’ computer systems. Bedep has the capability of downloading malware, so it will download the CryptXXX ransomware as a second-stage infection, dropping it as a delayed execution DLL and setting to wait 62 minutes before launching.

ProofPoint researchers believe that CryptXXX was developed by the same cybercrime gang who conducted the Reveton ransomware campaign in 2012, since they see similarities between CryptXXX and the older Reveton ransomware. The similarities inlcude: coded in Delphi; use a custom C&C protocol on TCP 443; use a delayed start; DLLs are named with a custom entry function; the directory of %AllUsersProfile% contains a .dat file; has the capability of stealing Bitcoins and credential.

After getting installed and executed, CryptXXX scans all the local hard drives, removable drives, and mapped drives for targeted file types and encrypt them after it attacks your computer. The ransomware searches for and encrypts files with the following extensions:



Having finished the encryption, the ransomware will create a text file, an image and an HTML webpage on the infected computer. The image is set as the desktop wallpaper; the HTML webpage is opened in a browser; while the text file is palced in the hard drive. They are all created to imform you that your files are encrypted by a strong encryption with RSA4096 and you have to make a payment for the private key and the decrypt program in order to get all your files back.

cryptxxx-ransomware ransom note



This page informs that your files are encrypted and to get the key to decrypt files you have to pay 500USD. If payment is not made before the specific time, the cost of the decrypting files will increase 2 times, namely you need to pay 1000 USD. You can directly make the payment on this page. It provides details on how to make the payment, how to download and use the decrypter use and also allows you to try decrypting one file for free before the payment. There is even the FAQ page that lists a series of questions and answers which may be helpful for you.

Should You Pay the Ransom?

Generally, it is not suggested to pay the ransom. Here are some reasons:

  1. By paying the ransom, you just encourage the cyber criminals to continue creating ransomware like CryptXXX to infect more computers and extort more money from the innocent computer users.
  2. There is no guarantee that paying the ransom will give you access to your files again. Paying the ransom could also make you a target for more malware.
  3. It is possible to decrypt files encrypted by the ransomware by using a decryption tool created by Kaspersky.

Surely, if you think the decrypted files are very important to you, so that you don’t allow anything to go wrong, then you can try making payment for the decrypter provided by the ransomware developers and see whether they will keep their promise.

What Should You Do after Being Attacked by a Crypto Ransomware?

Once you find that your PC has been attacked by a ransomware, the first thing you need to do is to disconnect the Internet so as to prevent the ransomware from downloading other types of malware on your PC. Then, you should identify the type of ransomware. You can take down the basic content of the ransom note and then search on Google using your phone or another healthy computer. You may find information about the ransomware, including its name, characteristics and others. Next, make a copy of your hard drive. If a free decryption tool is developed, you can try encrypting the encrypted files without worring the files would be damaged for unexpected reason. Afterwards, restart your PC into the Safe Mode and try using your antivirus program or any other more powerful malware removal tool to remove the ransomware. In case you want to pay the ransom, you’d better save a copy of the ransom note.

How to Decrypt and Restore the Encrypted Files?

Once you have successfully removed the ransomware, you can try decrypting and restore the files encrypted by the ransomware. We are not sure that all the methods introduced below are helpful. But you still can have a try before you make the payment.

Method 1: Decrypt the Files by Using Kaspersky’s RannohDecryptor

Kaspersky Labs has developed a decryption tool to decrypt files encrypted by CryptXXX. But unforunately, this tool is only effective when your computer gets infected by the CryptXXX versions 1.0 and 2.0. The version 3.0 of the ransomware has been added new capabilities including network share encryption, which makes it ineffective for the decryption tool to decrypt the files.If your computer is attacked by the latest version of the ransomware, you have to wait and see if Kaspersky can update their decryptor.

Method 2: Use File Recovery Software

If Kaspersky’s decryption tool cannot help you, then you can try using the following file recovery software to recover some of your original files:

Method 3: Use Shadow Volume Copies
