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.
