What is Azer ransomware virus?

CryptoMix Azer ransomware version emerges right after the defeat of Mole02 virus

Azer ransomware virus

Azer ransomware is an updated Cryptomix virus[1] version that appends .azer file extensions to encrypted files. It drops a ransomware note called _INTERESTING_INFORMACION_FOR_DECRYPT.TXT on the desktop.

The letter carries a short message asking to contact cyber criminals via or email addresses. If you noticed such ransomware on your computer, initiate Azer removal as soon as you can.

The Azer Cryptomix ransomware virus emerged shortly after a decryption tool for Mole02 ransomware was released[2]. This ransomware is a previous version of Cryptomix malware. Such scenario is typical to ransomware developers – they update the virus and continue spreading it so that existing data recovery tools would become useless.

The ransomware is obviously related to ransomware and Donald Trampo ransomware because the provided email addresses were used in slightly different ransomware campaigns previously.

The malicious virus completely corrupts the original file name, then appends one of the following extensions to encrypted data:

  • .-email-[].AZER;
  • .-email-[].AZER;

On top of that, we must add that this ransomware doesn’t communicate with a Command & Control server like the majority of similar viruses do. It functions in offline mode and has ten unique RSA-1024 encryption keys that are used to encrypt AES key that is utilized in data encryption.

Azer malware (Cryptomix version)Azer file extension virus is a malicious ransomware that encrypts files and marks each of them with extensions containing criminals' email address.

When we look back at the previous attempts to decrypt CryptoMix ransomware, we are hopeful that reverse malware engineers will succeed in creating a free decryptor shortly. Therefore, do not pay the ransom and remove Azer ransomware using ReimageIntego or another reputable malware removal tool.

Distribution of Azer alike CryptoMix ransomware viruses

Versions of CryptoMix are distributed via malicious spam, exploit kits, RDP attacks and other traditional ransomware distribution means. For this reason, you have to take all possible measures to protect your PC from its attack.

First of all, we suggest installing a good anti-malware software. The second thing that is simply a must-do is creating a data backup. Keep in mind that the backup should be stored in an external data storage device and kept away from your computer!

Finally, we suggest avoiding shady Internet websites, emails sent by unknown senders, and of course, illegal software. Interacting with such content can quickly result in an unexpected ransomware attack. If you are willing to learn some great computer security tricks, check out site[3].

For Azer removal, install a good anti-malware or anti-spyware program. If you do not have it, we suggest rebooting your PC into Safe Mode with Networking first. Download the tool only when in the Safe Mode.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Azer from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If you have a data backup, remove the virus and then import files from the backup to your computer. If you're worried about your files, we suggest creating another copy of the backup on a safe PC. 

In case you do not have a backup, try one of the provided techniques.

If your files are encrypted by Azer, you can use several methods to restore them:

Restore some files using data recovery tool

Data Recovery Pro is a standard tool that successfully restores various kinds of corrupted or even deleted files. We suggest testing it on .azer file extension files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Azer ransomware;
  • Restore them.

Windows Previous Versions method

Try this method in case you have created a System Restore Point in the past.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Azer and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting Azer ransomware virus

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
