FabSysCrypto virus Removal Guide

What is FabSysCrypto ransomware virus?

FabSysCrypto ransomware pretends to be Locky virus

FabSysCrypto virus is yet another HiddenTear ransomware spin-off[1]. However, it seems that this time ransomware crooks have big plans and seek to scare the victims greatly. To accomplish this goal, the developers of HiddenTear clone FabSysCrypto have designed a ransom note that looks almost identical to the one that Locky ransomware[2] leaves on the compromised computers. Once installed, the ransomware encrypts victim’s files and adds .locked file extension. This is strange because if the ransomware developers actually wanted to make this virus at least a bit similar to Locky, they would have chosen to add .locky or .zepto file extensions. However, the virus creates a ransom note called _HELP_instructions.txt, which is known to be used by many Locky ransomware versions. The FabSysCrypto malware searchers for files with these file extensions: .txt, .doc, .docx, .xls, .xlsx, .sln, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .php, .asp, .aspx, .html, .xml, .psd. Once it finds a target file, it encrypts it. Again, we want to remind you that this virus is not as dangerous as Locky and there are some third-party tools that might help you to decrypt .locked file extension files corrupted by this virus. Before you take any moves regarding data recovery[3], please remove FabSysCrypto virus using instructions provided below the article. We never advise ransomware victims to deal with ransomware removal in a manual way, so we suggest using anti-spyware or anti-malware tools for FabSysCrypto removal. We highly advise using these malware removers – FortectIntego or SpyHunter 5Combo Cleaner.
FabSysCrypto virusThis is how the FabSysCrypto ransom note looks like. It is clear that FabSysCrypto tries to make victim's believe that it is a Locky virus.

FabSysCrypto ransomware is yet another example why open-source malware is a bad thing[4]. Releasing a ransomware code for “educational” purposes is never good because such projects always get exploited by novice cyber criminals who hardly know how to code. Therefore, they take a prepared source code, make a few easy tweaks and customize it for their needs. Although such viruses are not as dangerous and sophisticated as, for example, Spora ransomware[5], they still do damage to the computer and waste computer user’s time. However, Hidden Tear spin-offs often appear to be decryptable, so we suggest you search the web for HiddenTear decryption tools.

How did the virus enter my computer?

Nowadays we see cybercriminals’ tendency to use social engineering skills rather than programming skills when trying to infect computers with ransomware. The most popular malware distribution technique is the same one as it was a year ago. Scammers still rely on malicious spam technique, which helps them to convince unsuspecting users to install ransomware on their systems without realizing what they are doing. It only takes a few minutes to craft an ingenious message and add a few legitimate-looking logos to it, attach a malicious attachment and send such email to thousands of victims. Once opened, the malicious email attachment contaminates the system and damages data stored on it.

How to safely remove FabSysCrypto ransomware from your system?

If you unwillingly installed FabSysCrypto virus on your computer and it damaged your files in a few minutes before you even realized what happened, we suggest you calm down. There is still some hope left, and we believe that sooner or later you will be able to restore your files. Before doing anything else, remove FabSysCrypto malware with anti-malware tools. Please read the FabSysCrypto removal instructions, which are provided below – they will help you to prepare the computer and help you to conjure FabSysCrypto away easier.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove FabSysCrypto from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

You can try to recover your files using methods explained below, however, the most efficient way to restore them is to import them to the computer from a backup. Please remember that the virus must be purged before trying to recover your files.

If your files are encrypted by FabSysCrypto, you can use several methods to restore them:

HiddenTear decryptor

There are some HiddenTear decryption tools available online, however, we are not 100% sure that they are safe to use, so we cannot provide you the download link. If you want to use them, please search the Internet to find them. You can use them at your own risk.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from FabSysCrypto and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

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.
