Remove Mbed Virus (.mbed Ransomware Files)

By | Posted on November 19, 2019 | Updated on December 2, 2019

Mbed ransomware is another supplementary virus by STOP/DJVU family. This group is known for making so many variants of ransomware and globally spreading them over the internet. Cyber criminals behind Mbed use different channels to deploy the malicious code but they gain higher infection rate through spam emails where the dangerous code is attached and purporting to be an important document. As a way to entice users into opening the file, attackers would normally accompany it with convincing message such as correspondence from a prominent company or organization.

Another way that is widely utilized to distribute Mbed ransomware is by bundling it to cracked software and share out to web users via unrestricted file download websites. On this instance, Mbed virus executes discreetly during the installation process. Unfortunately, this technique can evade security programs because the entire installation process was granted an administrative privilege by computer user.

Once Mbed ransomware is installed and running on the computer, the initial attack would be to drop additional executable files, each with own task. One file can disable anti-virus application and block internet access to security websites. Another one would simulate a software update ‘in progress’ to mask the encryption process that literally slows down system performance.

Mbed Infected Files

The focus of Mbed ransom virus is to lock majority of users files with a complex algorithm that is almost impossible to decode. We say “almost” because there is still hope in recovering .mbed files with the help of malware researchers and they prove themselves victorious in decrypting ransomware files in the past. Therefore, if data is encrypted by Mbed ransomware, the general advise is to archive the files and wait for the future release of recovery software. Paying the ransom demand is not recommended because according to security experts, this may just tolerate cyber criminals from developing more ransomware.

With regards to removal procedures, we made a simple steps below along with efficient anti-virus and anti-malware tool that victims can utilize to clean the infected computer.
