The Evolution of Ransomware - BlackMatter, A New Protagonist

After the successful attacks made by the Darkside Ransomware on the Colonial Pipe and the REvil Sodinokibi Ransomware on Kaseya, both ended their operations. This opened a gap for new ransomware extensions to appear in order to protagonists in the new attacks and in the so-called Ransomware as a Service (RaaS) which is the outsourcing of attacks. 

 

From this gap, some ransomware families emerged and entered the “dispute” such as BlackMatter Ransomware, Lockbit 2.0 Ransomware, among others. 

 

We have a lot to talk about these new ransomware families that are aiming to carry on the legacy of successful attacks left by Darkside and REvil Sodinokibi Ransomware. 

 

Let’s take a closer look at BlackMatter Ransomware. 

Recover BlackMatter Ransomware

BlackMatter Ransomware

At the end of July, BlackMatter appeared on a Russian forum claiming to be a ransomware that contains the best parts of Darkside and REvil Sodinokibi Ransomware, unlike its predecessors, it doesn’t have any restricted countries for attacks, like Russia, for example, and also does not encrypt all the files on the computer, but only a part, this is done so that the encryption time is reduced and the countermeasures do not have enough time to be activated. 

 

The only restrictions for targets are: 

 

  • Hospitals; 
  • Critical infrastructure facilities (nuclear plants, power plants, water treatment facilities); 
  • Oil and gas industry (pipelines, oil refineries); 
  • Defence industry; 
  • Non-profit companies; 
  • Government sector. 

These restrictions were posted by the BlackMatter developers themselves. These restrictions were made so that the same mistakes made by Darkside and REvil Sodinokibi do not happen again, mistakes that led to the termination of their services. These areas draw a lot of attention from government officials, particularly the US government. If your company is not part of these sectors, you are a target for them. 

 

Given all this “power” of BlackMatter, you may be wondering what countermeasures can be taken to avoid paying the ransom. 

BlackMatter Ransomware Encrypted File Recovery

Digital Recovery has developed an exclusive technology capable of recovering files encrypted by ransomware of any extension, we call it the Tracer. 

 

This recovery process can be done even without the decryption key, because we access the hard disk where the files were stored and we are able to reconstruct them. 

 

This type of recovery was impossible until two years ago, so there are still companies that say that recovering files attacked by ransomware is impossible. 

 

We did not accept this fact and invested heavily in the development of a suitable technology for this, and after a lot of investments and efforts, we were finally able to create this technology. This has saved our customers highly significant value for their companies. 

 

All our services follow the guidelines established by the GDPR (General Data Protection Regulation), so that the recovery of encrypted data is done safely and discreetly. In addition to following these guidelines, we also have an NDA (Non-Disclosure Agreement).

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.
Ransomware is designed to go unnoticed, so it can disable all system defences without being noticed and start the process of encrypting files. Even if ransomware goes unnoticed by the system, it can be noticed by the user, as it uses system resources to perform the encryption, which can slow down the system. Ransomware also changes file extensions. So look out for these signs: slowing down the system and adding extensions to files. To find out more, talk to our experts.
Yes, this is possible. You can restart the computer in safe mode, which will limit the action of the ransomware since the system resources will be locked. You can also disconnect the computer from the Internet, which can interrupt the hackers’ connection to your system, it should be noted that there are ransomwares that work even without being connected to the Internet. You can also run diagnostics to identify threats with your antivirus software, the vast majority of antivirus software have this function. But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and the hackers could not restore the files, even with the decryption key. In these cases, only a data recovery company, such as Digital Recovery, can recover the files. To find out more, talk to our experts.
Yes, the attacks mainly take place on holidays and weekends, in the early hours of the morning. These days are chosen because there are not many active users on the system, making it impossible to discover the attack before the encryption is complete. To find out more, talk to our experts.
The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman] -2048 and AES [Advanced Encryption Standard] encryption. To find out more, talk to our experts.
First of all, do not pay the ransom. No matter what the hackers say, there is no guarantee that the decryption key will actually be released after the ransom is paid. The first thing to do is to inform the authorities about the attack. Governments have specialised cybercrime departments that will investigate the attack. Next, check if your backups have been affected, if so, only a specialist data recovery company can recover your files, this is the next step. Contact Digital Recovery who will assist you in the full recovery of your files. To find out more, talk to our experts.
After contacting us and sending the affected media, we will diagnose the device to verify the extent of the damage caused by the ransomware, which will allow us to predict the duration of the process and provide the client with a budget. Once the budget is approved by the client, we begin the recovery process, for which we have proprietary software that can, with the help of our specialists, reconstruct the data. If the client opts for remote recovery, instead of sending us the media, they will send the encrypted files to a virtual environment, totally secure, so that we can access them. At the end of the process, we will perform a double check so that the customer can verify the integrity of the recovered files. Payment is only made once the files have been delivered and validated by the client. To find out more, talk to our experts.
