ZES Ransomware

Ransomware Alert

What is ZES Ransomware?

ZES ransomware is a malicious software program that infiltrates a system, locking the user’s data and demanding a ransom fee to unlock them. This malware is part of the Makop malware family and was first discovered in August 2020. The virus is designed to attack computer users around the world, encrypting personal items such as pictures, files, databases, documents, and many more. It uses powerful algorithms like RSA and AES to encrypt files, hence diminishing hopes of recovering the encrypted data. Each encrypted file can be seen by the victim appended with a .zes extension.

Apart from the locked data, victims are served with a ransom note titled readme-warning.txt saved on the desktop. The note explains how the perpetrators have locked data and what the victim must do to regain access. They also let the victim know that a unique key for unlocking files exists only with them and they should pay in Bitcoin currency if they wish to recover data. The note reads:

::: Greetings :::

Little FAQ:
Q: Whats Happen?
A: Your files have been encrypted and now have the “zes” extension. The file structure was not damaged, we did everything possible so that this could not happen.

Q: How to recover files?
A: If you wish to decrypt your files you will need to pay in bitcoins.

Q: What about guarantees?
A: Its just a business. We absolutely do not care about you and your deals, except getting benefits. If we do not do our work and liabilities – nobody will cooperate with us. Its not in our interests.
To check the ability of returning files, you can send to us any 2 files with SIMPLE extensions(jpg,xls,doc, etc… not databases!) and low sizes(max 1 mb), we will decrypt them and send back to you. That is our guarantee.

Q: How to contact with you?
A: You can write us to our mailbox: johncastle@msgsafe.io

Q: How will the decryption process proceed after payment?
A: After payment we will send to you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files.

Q: If I donít want to pay bad people like you?
A: If you will not cooperate with our service – for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice – time is much more valuable than money.

DON’T try to change encrypted files by yourself!
If you will try to use any third party software for restoring your data or antivirus solutions – please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.

There are several distribution techniques used by ZES authors. Unfortunately, since this type of ransomware is still new, once it attacks, there is less to no hope of recovering files. Careless internet users form the majority of ZES victims since the virus orchestrators send malicious emails in bulk globally. Other techniques used to distribute ZES ransomware include:

  • Software vulnerabilities
  • Browser fake updates
  • Insecure Wi-Fi connections
  • Pirated installations

Just like any other malicious program, the ZES ransomware can be prevented by observing and practicing precautionary measures, such as ensuring the installed programs and the operating system are constantly being update, armoring your computer with a trusted anti-malware security tool, staying away from insecure websites which include torrents and pirated content distributors, and most importantly, remotely backing up all of your important files.

If your system is infected by the ZES ransomware, there is nothing you can do to recover the encrypted files. So, you should concentrate on removing the virus instead, and try other means of recovering your data from remote backups without paying the criminals.

What Does ZES Ransomware Do?

When this malicious software infiltrates the system, it modifies Windows systems, preparing it for uninterrupted file encryption. For instance, the ZES ransomware deletes Shadow Volume Copies as well as other in-built system recovery options. Such characteristics make file recovery without the decrypting key almost impossible.

To ensure that victims are pressured to pay, this ransomware targets files that are commonly used such as PDF, Microsoft Office documents (word, excel, PowerPoint, etc.), archives, and many more.

Regardless of how important the encrypted data is, at this point, it’s best to consider it as lost. We don’t advise paying even a fraction of the ransom fee to avoid further loss. Rather, take that money and invest it on a reliable security software tool to avoid a repeat in the future. Moreover, paying a ransom fee does not guarantee the return of your files. Thus, by paying, you risk losing your money in addition to the data that is already encrypted.

How to Remove ZES Ransomware

At this point, you understand that recovering files encrypted by ZES ransomware without the decryption key is nearly impossible. So, focusing on removing the virus before attempting to recover files via other means is ideal. If you have a remote backup, it’s best to get rid of the ZES ransomware first to avoid a secondary attack. This will require a reputable and trusted anti-malware software. You must first create a backup of the encrypted files using a separate, external medium. This will help you recover some, if not all of the files in the future, once a decryption tool has been released.

In most cases, after scanning the system and getting rid of the virus, the computer may experience crashes or BSODs. This can be due to the system files corrupted by the ZES ransomware. However, you don’t have to reinstall the operating system. With the help of a strong PC repair software tool, you can fix corrupted system files.

ZES Ransomware Removal Instructions

Ransomware crime is considered to be one of the most lethal cybercrimes due to its capability of locking files. It is dangerous and destructive in all sorts of levels such that one has to act accordingly once they notice it in their system. Apart from locking files, it can also damage your system to a point of paying an arm and leg to get it fixed.

We emphasize on not tolerating the idea of paying the ransom fee because even if you get the files back, criminals already have access to your system and can repeat the same attack in the future. The ZES ransomware uses a symmetric and an asymmetric encryption technique, making it impossible to recover data without the key that is in possession of the cybercriminals.

To get rid of the ransomware, here are the options that you have:

  1. Try out third-party tools that can hopefully recover a fraction of the encrypted files from the storage drive.
  2. Make use of the automated Windows backup systems like the Windows Previous Versions to try and recover data.
  3. Make a copy of the encrypted data, and then wait for security researchers to release a decrypting tool (note that the timeframe may vary from months to years).

Taking everything into consideration, here is a step by step process to removing the ZES ransomware from your system permanently. Remember to have a copy of the encrypted files before executing this removal procedure:
