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.

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.
