Xorist ransomware developers keeps releasing new versions in 2018

Xorist ransomware virus

Xorist signifies the group of ransomware viruses that emerged in April 2016. Malware is developed using Encoder Builder v.24 from [Pastorok][1] and uses either XOR or TEA encryption algorithm to corrupt files on the affected computer. Currently, Xorist ransomware uses .cryptedx file extension to mark affected files and attaches it to every file that was affected. All extensions that it has ever used were included to this list:

  • .antihacker2017;
  • .pa2384259;
  • .hello;
  • .brb;
  • .RusVon;
  • .xdata;
  • .SaMsUnG;
  • .zixer2;
  • .error;
  • .errorfiles;
  • .@EnCrYpTeD2016@;
  • .encoderpass;
  • .fileiscryptedhard;
  • .6FKR8d;
  • .EnCiPhErEd;
  • .73i87A;
  • .p5tkjw;
  • .PoAr2w;
  • .ava.

However, you should note that the virus has been updated numerous times. The latest Xorist ransomware variant has been spotted at the beginning of February 2018 and is dubbed as Xorist-Frozen. 

According to the researchers, the performance of the Xorist ransomware and its versions are very similar for the most part. When all the targeted files are taken to the hostage, Xorist virus downloads a ransom note and drops it on the desktop. The HOW TO DECRYPT FILE.TXT file is used by criminals to explain that users have to pay the ransom. 

The communication method is quite strange. The victims of the original ransomware virus have to send the SMS message to the provided numbers instead of using Bitcoin payment system. [2] 

When the developer of the virus supposedly sends a unique decryption password for the victim. The victim needs to enter this password into a Password Prompt, and then the files should be decrypted. However, the number of attempts to enter the password is limited by the creator of the virus. If the victim exceeds the number of attempts to type in the right password, user’s data will be lost forever.

In the meanwhile, the Xorist-Frozen virus does not intimidate people by the number of excessive number of attempts to enter the code. Now the victim is informed that the server will destroy the key within 36 hours after the encryption, but the payment has to be transferred within 24 hours. However, instead of listening to hackers, make sure to remove Xorist-Frozen completely. 

Following these orders is neither necessary nor recommended[3] because ransomware is already decryptable. Even its latest variant Cryptedx ransomware can be beaten. Thanks to security researchers, you can use free software to recover corrupted data. However, before using this tool, you should remove Xorist ransomware from the computer using Reimage, Malwarebytes Anti Malware, or another anti-malware.

Variations of the Xorist malware

Team Xrat ransomware

This version has been discovered on August 2016 targeting Portuguese[4] computer users. The virus encrypts files with RSA-2048 encoding system and hides the decryption key. To the encrypted files, malware appends .C0rp0r@c@0Xr@ file extension and delivers a ransom note “Como descriptografar seus arquivos.txt.”

Victims are told to contact authors of this virus via email address and learn how to obtain the decryptor. However, doing that is unnecessary because ransomware can be decrypted for free with Team Xrat decryption tool.

XPan ransomware virus

Malware emerged in September 2016. It uses AES-256 encryption and appends either .____xratteamLucked and .one file extensions. The unique feature of the ransomware is that after infiltration it check the default language of the computer.

The ransom-demanding message does not inform how much Bitcoins victims have to transfer. However, some people claim that they were asked to pay 0.3 BTC. However, this piece of crypto-malware is poorly written, and users can recover their files for free after XPan removal.

Zixer2 ransomware virus

This variant of the Xorist uses Tiny Encryption Algorithm and appends .zixer2 file extension. Following data encryption, it delivers a ransom note in HOW TO DECRYPT FILES.TXT file. Here victims are asked to contact cyber criminals via email address.

It’s unknown how much money crooks ask in exchange for the decryption key. However, victims do not need to waste their time chatting with hackers. Once the malware is wiped out from the system, people can recover their files with Xorist Decrypter.

Imme ransomware virus

Malware uses XOR encryption algorithm and appends .imme or .imme.teras.completecrypt file extensions. In the ransom note, hackers demand to pay 2 Bitcoins within 72 hours for data recovery tool. The threatening message also reveals unique user’s ID that victims have to send or as soon as they pay the ransom. However, just like the other variants of Xorist, this one is also decryptable.

AvastVirusinfo ransomware virus

This variant aims at Russian-speaking computer users. It appends .[8 random chars] extension to each of the targeted file and installs a ransom note called “КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt,” Here crooks ask to contact them via and pay only $15.Nevertheless, the ransom is small; there’s no need to pay it because ransomware is decryptable for free.

Crypto1CoinBlocker ransomware virus

Malware uses RSA-2048 cryptography to encode files on the affected computer. When all files are encrypted, ransomware delivers a pop-up window with a ransom-demanding message. The same data recovery instructions are provided in the HOW TO DECRYPT FILES.txt file too.

Cyber criminals ask to transfer 1 Bitcoin to the provided wallet address. What is interesting, that Bitcoin wallet address is the same as the appended file extension – .1AcTiv7HDn82LmJHaUfqx9KGG55P9jCMyy. However, paying the ransom is not recommended. After Crypto1CoinBlocker removal, users are advised to try alternative recovery methods.

Hello ransomware

It’s the recent variant of Xorist malware that emerged in August 2017. Malware spreads and is executed from the iji.exe file. Once this file is run on the system, it starts scanning the system and looking for the targeted files. To all of the encrypted data it appends .HELLO file extension.

The virus also delivers a pop-up window informing about encrypted data. What is more, it also installs a ransom note called HOW TO DECRYPT FILES.txt where victims are asked to transfer 0.05 BTC to the provided address. Users are given 12 hours to complete this task. After the deadline, the price will double. However, after 24 hours corrupted files are said to be deleted. crypto-virus

Despite the reference to the notorious Cerber ransomware, the malware happens to be another version of Xorist virus. It is common technique among cyber criminals to threaten users with more menacing virtual threats. On the other hand, this malware is still capable of encoding users' files, appending extension and demanding ransom.

The malware is still under development so it only presents demands in HOW_TO_DECRYPT.txt file. No specific sum of ransom is indicated. Users should not consider paying the ransom as they might make use of free Xorist Decrypter.

Cryptedx ransomware 

This is the newest version of Xorist crypto-malware. The virus is already detected by 53 security software vendors as dawdawd.exe. Fortunately, just like previous its versions, it can be decrypted with the help of Emsisoft decrypter.

When infected, you can find that all of your files are inaccessible. Besides, their endings will be changed to .cryptedx file extension. In this case, you should ignore warning message which is also dropped by malware developers, and remove Cryptedx ransomware from the system. Then, move on to files' recovery guide posted in the end of this description.

Xorist-Frozen ransomware

Xorist-Frozen is the latest Xorist ransomware version that has been detected at the beginning of February 2018. According to the latest reports, the Xorist-Frozen is very similar to its predecessors. It uses XOR file encryption algorithm and creates a HOW TO DECRYPT FILES.txt ransom note. Currently, the file extension appended to the encrypted files is not known. 

Xorist-Frozen ransomware asks to pay 0.5 BTC ransom, which is currently around 3400 USD and transfer it within 24 hours. Extortionists claim that all locked files will be removed from the server within 34 hours after the encryption.

In comparison to its predecessor's communication method, this version has switched from the SMS to email, so people who opt for a unique decryption code has to send a code to Based on the prevalence of the virus, it's oriented toward English-speaking countries. 

Security experts haven't yet developed a Xorist-Frozen decryptor. Therefore, there's only one way out – to remove the virus with a professional anti-virus and then try to decrypt data using the methods given at the end of this post. 

5 tips to protect your PC from file-encrypting threats

Cyber criminals use various techniques to spread this virus, such as malicious spam emails, malvertising, fake or illegal downloads, etc. However, by following a few simple rules, you can reduce the risk of getting a computer virus.

  1. First of all, never open emails that come from unknown senders. In addition to that, avoid reading emails that fall into “Spam” category. Sending viruses and trojans via email is one of the most popular ways to distribute malicious computer viruses.[5]
  2. Do not click on suspicious content while you browse the Internet. If you see doubtfully reliable ads or banners that claim you have won millions or that you are the lucky visitor, ignore them. Such ads are deceptive.
  3. Download files only from trustworthy web sources. Besides, you should save them to your computer system instead of running/opening them immediately. It gives your computer security software some time to scan the file and test its reliability.
  4. Backup your files. It is a must! If you do not know why you should do that, please read this post – Why do I need backup and what options do I have for that?
  5. Protect your computer with a trustworthy anti-spyware or anti-malware software.
