What is Besub ransomware?

Besub ransomware – a STOP virus version that can successfully infiltrate AZORult trojan

Besub ransomware virusBesub ransomware is malware that might inject AZORult trojan into the system

Besub ransomware is a newly discovered malware strain that comes from Djvu and STOP families. The threat aims to modify entries on the infected computer and inject its own malicious payload. Once this happens, Besub virus initiates the encryption process by using unique ciphers and appends the .besub file extension to each component. After that, the malware passes the _readme.txt message to its victims and urges a ransom of $490 that will double if no communication is made in a three day time period. Also, the ransomware appears to be associated with a random-character file that contains the malicious payload in the size of 575.5 KB and has been spotted infectious by 56 AV engines on Virus Total.

All STOP ransomware versions, including Besub ransomware, are known for spreading AZORult trojan. You need to be extremely careful while dealing with cyber threats from the STOP family as they might bring additional malware to your vulnerable system which might relate to even a more severe computer or software damage.

Continuously, users who are affected by Besub ransomware will supposedly see suspicious alterings in their Windows Registry and Task Manager sections. Note that this malware needs to inject additional files to be able to run its own malicious processes on the targeted system. This way the virus can successfully work in the background.

This way you will avoid unnecessary money losses and might restore some blocked information.

However, note that Besub ransomware removal is a crucial step to take before you continue with data recovery. Restoring data before the malware elimination is a completely useless action to take as the malicious payload would still be running and would repeat the encryption all over again.

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.
