BlackToxic ransomware (Recovery Instructions Included)

BlackToxic virus Removal Guide

What is BlackToxic ransomware?

BlackToxic ransomware is a file-locking virus that changes the desktop background and delivers a note

BlackToxic ransomwareBlackToxic ransomware is a file-encrypting virus that asks for a ransom in exchange for a decryption tool

BlackToxic is a ransomware-type virus that locks all personal files upon installation and then demands a ransom to be paid in return for a decryption tool. It stems from an established malware family known as Chaos – we have already covered its previous versions, including Odaku and LockData. BlackToxic is the newest version that was first spotted at the end of May 2022.

Once installed, the malware looks for the most commonly used files, including pictures, databases, documents, videos, etc. During the encryption process, the virus locks all files with the help of a strong encryption algorithm,[1] which makes the unlocking process almost impossible without a unique key.

During this time, all files are appended with a randomly-generated file extension, consisting of alphanumeric characters, for example, .JriKd8f6. They are also stripped of their original file icons, which only leaves a blank sheet icon instead. This points out that BlackToxic files are no longer as they are used to be – they can't be modified or even opened. At this point, malware delivers the read_it.txt file and changes the background wallpaper.

Crooks claim that a ransom needs to be sent to 1NScbuZLaqt88Q3qr6baeiJVmZNuNSdS7k crypto wallet, although they don't specify the sum. We do not recommend cooperating and instead use alternative solutions provided below.

Name BlackToxic virus
Type Ransomware, file-locking malware
File extension A combination of random characters is appended to each of the files, for example, a picture.jpg is turned into picture.jpg.JriKd8f6
Ransom note read_it.txt
File Recovery The only secure way to restore files is by using data backups. If such is not available or were encrypted as well, options for recovery are very limited – we provide all possible solutions below
Malware removal Disconnect the computer from the network and internet and then perform a full system scan with SpyHunter 5Combo Cleaner security software
System fix Once installed on the system, malware might seriously damage some system files, resulting in crashes, errors, and other stability issues. You can employ ReimageIntego PC repair to fix any of such damage automatically by replacing system corruption

The ransom note

Most ransomware strains, such as Djvu, are very consistent when it comes to their versions. Most commonly, changes are made to contact email addresses and a few other variables. While BlackToxic uses the same ransom note title as its previous versions (read_it.txt), the contents of the ransom note vary greatly.

In this note, for example, contact details and the sum which should be paid to the provided wallet are abundant and is also not clear. Crooks also resort to trying to frighten victims in various ways:

you must pay within 48hrs or your files is not going to be recoverd by this ransome unless you pay
otherwise as we have the decryption key that will help you to revover your important files!!!!!!!

Why you shouldn't pay

The main goal of cybercriminals of almost every ransomware is to ensure that victims pay money in digital currency, usually Bitcoin. They use all types of tactics for this to happen – threatening to disclose the found files publically, delete the decryption key within a certain amount of time, or even trying to seem friendly and nice.

BlackToxic ransomware virusBlackToxic does not provide any contact details

In the case of BlackToxic ransomware, hackers even resort to phishing techniques by claiming that the FBI or hitmen could be saying on the stolen files, which is absolutely a ludicrous statement and just another attempt to frighten users and make them pay the ransom.

Paying cybercriminals is always risky – they are not obliged to send you a decryption tool, so there are no guarantees. While some malware strains are known for delivering what they promised, some don't, and it can also vary on a case-to-case basis. By paying, you are risking losing your files and money.

Besides, it would only prove to crooks that their illegal business scheme works well and encourage them to continue developing ransomware, infecting even more people worldwide.

Ransomware removal

As soon as the BlackToxic virus infiltrates a Windows system, it soon establishes a connection with a remote C2 server.[2] With the help of this connection, cybercriminals might start sending commands for execution, change various parameters, or even result in further malware infections.

Therefore, before you proceed with malware removal, it is mandatory to disconnect your computer from the internet. The easiest way to do that is by disconnecting your ethernet cable or stopping the WiFi connection via the task manager. If you have several computers or/and they are connected to a network, use the following instructions:

  • Type in Control Panel in Windows search and press Enter
  • Go to Network and InternetNetwork and internet
  • Click Network and Sharing CenterNetwork and internet 2
  • On the left, pick Change adapter settingsNetwork and internet 3
  • Right-click on your connection (for example, Ethernet), and select DisableNetwork and internet 4
  • Confirm with Yes.

Once you are sure that the system is not connected to the network, you should use powerful anti-malware software and perform a full system scan with it. Security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, can find and remove all the malicious components from the system at once and any secondary payloads that might be present on the system.

Data recovery options

There are two types of virus victims affected by ransomware: some of them get scared and believe that their files have been permanently damaged, and the other part of users think that they can get the BlackToxic ransomware encrypted files with the help of security software. Unfortunately, none of these statements are true.

Encryption is a complex process that uses a unique key for each of the victims. This means that, without it, people are unable to unlock the data – it is important to keep in mind that files are not corrupted in any capacity, they are just inaccessible without the decryptor. Security software is not designed for the recovery of files encrypted by ransomware, so while a scan will remove the infection, it would not restore personal files to a working condition.

Luckily, there are a few alternative options available, although the success rate is relatively low. You can try using data recovery software or waiting for a decryptor.

  • Download Data Recovery Pro.
  • Double-click the installer to launch it.
    BlackToxic ransomware
  • Follow on-screen instructions to install the software.
  • As soon as you press Finish, you can use the app.
  • Select Everything or pick individual folders which you want the files to be recovered from.Select what to recover
  • Press Next.
  • At the bottom, enable Deep scan and pick which Disks you want to be scanned.Select Deep scan
  • Press Scan and wait till it is complete.Scan
  • You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  • Press Recover to retrieve your files.

If security researchers manage to find bugs within the ransomware encryption process or if the attackers' servers get seized by the authorities, a free decryptor can be released to victims. This might or might not happen in the future; the below links can provide you with more information.

No More Ransom Project

System fix

After malware infection, Windows is no longer the same, as some system files might get damaged or even destroyed. This can result in system instability – crashes, failure to launch programs, BSODs,[3] and many other issues. If you are suffering from these problems after eliminating the infection, use data recovery software as explained below.

  • Download ReimageIntego
  • Click on the ReimageRepair.exe
    Reimage download
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation processReimage installation
  • The analysis of your machine will begin immediatelyReimage scan
  • Once complete, check the results – they will be listed in the Summary
  • You can now click on each of the issues and fix them manually
  • If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.Reimage results

After all these steps are completed, you should ensure to prepare backups of your personal files to avoid devastating ransomware attack consequences. Likewise, reporting the incident to the authorities can help it to tackle cybercrime and increase the probability of cybercriminals' server seizures.

Getting rid of BlackToxic virus. Follow these steps

Create data backups to avoid file loss in the future

One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.

Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:

  • Backup on a physical external drive, such as a USB flash drive or external HDD.
  • Use cloud storage services.

The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.

Using Microsoft OneDrive

OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:

  1. Click on the OneDrive icon within your system tray.
  2. Select Help & Settings > Settings.
    Go to OneDrive settings
  3. If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
    Add OneDrive account
  4. Once done, move to the Backup tab and click Manage backup.
    Manage backup
  5. Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
  6. Press Start backup.
    Pick which folders to sync

After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).

Using Google Drive

Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.

You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.

  1. Download the Google Drive app installer and click on it.
    Install Google Drive app
  2. Wait a few seconds for it to be installed. Complete installation
  3. Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
    Google Drive Sign in
  4. Click Get Started. Backup and sync
  5. Enter all the required information – your email/phone, and password. Enter email/phone
  6. Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
  7. Once done, pick Next. Choose what to sync
  8. Now you can select to sync items to be visible on your computer.
  9. Finally, press Start and wait till the sync is complete. Your files are now being backed up.

Report the incident to your local authorities

Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.

Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:

Internet Crime Complaint Center IC3

If your country is not listed above, you should contact the local police department or communications center.

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.
