OXAR Ransomware – Distribution

Several methods could be used for the distribution of OXAR’s payload. Mainly it may be spread in email spam campaigns in the form of attached files. In order to seem legit and make you more prone to open the attached files, such emails may impersonate representatives of well-known companies or even governmental institutions. The attached malicious files usually come as documents, archives, images and other commonly used file formats. The text message may be trying to convince you that you need to download and open the attached file as soon as possible. For the sake of your security, you could use a free online file extractor each time you download new file on your PC. Tools of this kind could quickly identify whether a file contains malicious elements or not by scanning its code for particular traits. Thus it could help you to avoid opening malicious files that plague your device.

Ransomware may infiltrate computer systems with the help of corrupted web pages as well. Bad actors could inject the malicious code into the source code of target web pages or and set them to download it directly on the devices of tricked users. They could also create copies of some pages and modify their components so they can download and automatically the ransomware after a user visits the corrupted page. As regards the malicious URLs of these web pages, they could be posted on social media channels, send in emails and spread via instant messaging services. Potentially unwanted programs that alter browser settings and cause numerous redirects to sites of unknown origin are often used for ransomware distribution as well.

OXAR Ransomware – More About the Infection

The infection begins once OXAR’s payload is running on the system. The threat aims to modify some essential system settings in order to plague it and achieve persistence. It is highly possible that OXAR will add malicious values under the registry sub-keys Run and RunOnce which will ensure its automatic execution on each Windows system start.

OXAR crypto virus may also be designed to scan the system for particular details so it can then send them to its command and control server. Once the threat establishes a connection with its server, it may drop additional malicious files on the compromised host. If you want to prevent malicious intenders from stealing sensitive data of yours, you should remove all ransomware files and objects from the PC immediately after infection.

At the end OXAR crypto virus drops a ransom note file to blackmail victims into paying a ransom for a decryption solution that can decrypt .FUCK files. The message could be found in a file named 1 What happens with my files.txt. Below you could see what it reads:

No matter what hackers state, be advised to avoid ransom payment and remove the threat as soon as possible. Almost all ransomware viruses that are based on HuddenTear have been decrypted by security experts. So, the code of this new OXAR strain is expected to be cracked soon after the analyses of its samples are done. Expect us to update this article with the decryptor once it is released. Meanwhile, you could try to restore some of your .FUCK files with the help of the alternative data recovery solutions mentioned in the guide that follows.

OXAR Ransomware – Data Encryption

The encryption is applied to all types of files listed in the code of OXAR ransomware. The threat is likely to use strong cipher algorithm or combination of a few in order to modify the original code of target files and render them completely inaccessible. As OXAR is a HiddenTear based ransomware it is believed that all files that have one of the following extensions get encrypted after infection:

→.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .hwp, .pdf, .php, .asp, .aspx, .html, .xml, and .psd

Once files are corrupted they all receive the specific extension .FUCK that stands at the end of their names. You cannot open .FUCK files until a proper decryption solution that reverts their code is applied. But before you rush into ransom payment be advised to check out the alternative data recovery solutions listed in the guide below. By paying the ransom you only risk to lose your money and still have your .FUCK corrupted. There is no guarantee that bad actors will provide a working solution as often the ransomware code gets broken and doesn’t generate an efficient decryption key.
