Marozka virus Removal Guide

What is Marozka ransomware?

Marozka ransomware is a cryptovirus that was developed by English and Russian hackers as stated in the ransom note

Marozka ransomwareMarozka ransomware virus is the program based on open-source HiddenTear ransomware which encrypts users files to demand the payment. Marozka cryptovirus is the HiddenTear ransomware that marks files with .Marozka extension when they get encrypted and locked. The encryption is based on an army-grade algorithm, in this case, AES-256. The process focuses on changing the original code of selected files and marking them using a specific file marker .Marozka. Then, the ransom note can be generated and added to every folder alongside encrypted files. HOW TO DECRYPT FILES.txt delivers a ransom message and provides the link for Marozka-decryptor. Once visited, the window states that the amount of ransom is $100 in Bitcoin. Besides this message, the virus also changes the Desktop wallpaper, and the displayed image also says ” Your files were encrypted.” These crypto-extortionists give 24 hours for victims to pay for the alleged decryption. But there is little possibility that virus developers recover encrypted files after the payment, even when the victim is a big company.[1]

According to Marozka ransomware virus developers, files encrypted by this threat cannot be opened without paying the ransom. Data becomes useless when the code gets changed with the help of encryption algorithm.[2]

Then Marozka ransomware ransom note is displayed on the desktop as the wallpaper and instructs victims to read the text file named HOW TO DECRYPT FILES.txt. The message in this file reads the following:

All your information (documents, databases, backups and other files) this computer was encrypted using the most cryptographic algorithms.
All encrypted files are formatted .Marozka.

Marozka ransomware provides a website where the payment methods get listed, and the Marozka-Decryptor is displayed. Cybercriminals offer to buy a decoder there and give 24 hours for the victim to contact them or straight up pay the ransom.

When Marozka ransomware gets on the system, it adds various files to Desktop, User_folders, and similar directories. It also installs Marozka.jpg and Marozka.exe on the system to ensure the persistence of this malicious product and this way runs on the machine uninterrupted.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
