If you cannot open your images, documents, or files and they have a .[ops@mailc.net].ZOZL extension, then your computer is infected with the Phobos ransomware.

The ZOZL Ransomware is a malicious program that encrypts the personal documents found on the victim’s computer with the “.[ops@mailc.net].ZOZL” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop as the ops@mailc.net pop-up window and in the “info.txt” text file.

What is the ZOZL ransomware?

ZOZL is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.[ops@mailc.net].ZOZL” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.

The ZOZL ransomware will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.[ops@mailc.net].ZOZL”, so that you are no longer able to be open them.

Once the ZOZL ransomware has encrypted the files on your computer, it will display the “info.txt” text file that contains the ransom note and instructions on how to contact the authors of this ransomware. The victims of this ransomware will be asked to contact the cybercriminals via the ops@mailc.net email address.

This is the ransom note that the ZOZL ransomware will show to its victims:

All your files have been encrypted!

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail ops@mailc.net
Write this ID in the title of your message –
In case of no answer in 24 hours write us to this e-mail: ops@mailc.net
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the tool that will decrypt all your files.

Free decryption as guarantee
Before paying you can send us up to 5 files for free decryption. The total size of files must be less than 4Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)

How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click ‘Buy bitcoins’, and select the seller by payment method and price.

Attention!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam..

Unfortunately, it is not currently possible to decrypt the files encrypted by the ZOZL ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.

Here is a short summary for the ZOZL ransomware:

  • Ransomware family: Phobos ransomware
  • Extensions: ZOZL
  • Ransomware note: info.txt
  • Ransom: From $500 (in Bitcoins)
  • Contact: ops@mailc.net
  • Symptoms: The images, videos, and other documents have the “.[ops@mailc.net].ZOZL” extension and cannot be opened by any programs

How did the ZOZL ransomware get on my computer?

The ZOZL ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.

Here’s how the ZOZL ransomware might get on your computer:

  • Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the ZOZL ransomware.
  • The ZOZL ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.

How to remove ZOZL ransomware (Virus Removal Guide)

STEP 5: Restore the files encrypted by the ZOZL ransomware

Unfortunately, it’s not possible to recover the files encrypted by the ZOZL ransomware because the private key which is needed to unlock the encrypted files is only available through the ecybercriminals. However, below we’ve listed three methods you can use to try and recover your files.

Make sure you remove the malware from your computer first, otherwise, it will repeatedly lock your system or encrypt files. If you suspect that your computer is still infected with malware, you can run a free scan with ESET Online Scanner.

Method 1: Search for a ZOZL ransomware decryption tool

At the time of writing this article, there was no decryption tool available for the ZOZL ransomware. However, the cybersecurity community is constantly working to create ransomware decryption tools, so you can try to search these sites for updates:

Method 2: Try to recover your files with Recuva Free

With this second option, we will install and try to recover the encrypted files with Recuva, a free data recovery tool.

  1. Download Recuva Free.

    You can download Recuva from the below link.

    RECUVA FREE DOWNLOAD LINK
    (This link will open a new web page from where you can download Recuva Free)

  2. Install Recuva.

    Double-click on the rcsetup setup file to start the installation process, then follow the on-screen promts to install this program.
    Install Recuva

  4. Select the files you want to recover.

    Recuva will scan your computer, and once it’s finished it will display a list of all the files that were detected. Select the check boxes beside the file or files you want to restore. The color of the dot next to the file name indicates your chances for a successful recovery (green for excellent, orange for acceptable, and red for unlikely).

    Recover Files 1

  5. Click “Recover”.

    Once you have selected the files you want to recover, click on “Recover”. Select a destination for the recovered files, then click on “Ok”.

Method 3: Try to restore your files with ShadowExplorer

The ZOZL ransomware will attempt to delete all shadow copies when you first start any executable on your computer after becoming infected. Thankfully, the infection is not always able to remove the shadow copies, so you should continue to try restoring your files using this method.

  1. Download ShadowExplorer.

    You can download ShadowExplorer from the below link.

    SHADOW EXPLORER DOWNLOAD LINK
    (This link will open a new web page from where you can download “ShadowExplorer”)

  2. Install ShadowExplorer.

    Select drive and date to recover the files encrypted by ZOZL ransomware

  4. Export the files that you want to recover.

    Once you have found a copy of the original file or folder, right-click on it and the select “Export”. A window will prompt you where you want to save the file or folder.
    Find copy then click on Expor to recover the files encrypted by the ZOZL ransomware

Your computer should now be free of the ZOZL ransomware infection. If your current antivirus allowed this malicious program on your computer, you may want to consider purchasing the full-featured version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
If you are still having problems with your computer after completing these instructions, then please follow one of the steps:

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
