RedBoot virus functions as a hybrid behavior of both, file-encrypting virus and a wiper. It encrypts data, appends .locked file extension, and completely overwrites Master Boot Record (MBR). The latter is responsible for how system partitions containing file systems operate. The malware also tends to modify hard drive partitions irrevocably.

Though the virus encodes data, it does not indicate the service where a user can require for Redboot Decrypter. Unless the perpetrator has the tool associated with each victim‘s computer, the decryption process is futile.[1] The malware also delivers 5 files into the system:

  • assembler.exe
  • boot.asm
  • boot.bin
  • overwrite.exe
  • main.exe
  • protect.exe

Some of the files are used to compile others and, likewise, prepare for the rewriting process of MBR. The mission to do so lies on the overwrite.exe file. Additionally, the malware developers programmed the malware likewise that the users will not interrupt with the activity of the files. Protect.exe file prevents users from launching Task Manager and ProcessHacker.

Despite this, it is necessary to remove RedBoot virus as soon as possible. FortectIntego or Malwarebytes will assist you in this process. Below instructions will explain how to bypass the intervention of the malware.

In other words, while the detection rate of the malware is still low, but it is now found as Win32.Trojan.Mbrmodifier.Auto, Win32:Malware-gen, etc[2]. Thus, it is necessary to perform RedBoot removal right away.

Transmission techniques

The malware is likely to fish for new victims via spam emails or infected torrent files. In order to maximize the number of infected emails, the services of a botnet are used. As in the case of Ykcol (Locky) which employs Necurs botnet, RedBoot ransomware might be using this one as well.

Users should also be wary of corrupted apps and browser extensions. Currently, Google Chrome Web Store has been under cyber siege. Thus, besides cautiously installing new apps and extensions, fortify the protection of the PC with multiple malware removal and anti-virus tools. If updated, they will help you escape similar RedBoot hijack in the future.

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.
