The Evolution of Ransomware - BlackMatter, A New Player

After the successful attacks made by the Darkside ransomware on the Colonial Pipe pipeline and the REvil Sodinokibi ransomware on Kaseya, both have shut down. This caused a gap to be opened for new ransomware extensions to appear seeking a leading role in attacks and so-called Ransomware-as-a-Service (RaaS) which is the outsourcing of attacks.

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

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

Let’s take a closer look at the BlackMatter ransomware.

Recover Ransomware BlackMatter

Ransomware BlackMatter

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

The only restrictions on targets are:

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

These restrictions have been disclosed by the BlackMatter developers themselves. These restrictions were made so that the same mistakes made by Darkside and REvil Sodinokibi would not happen again, mistakes that led to the closure of their services. These areas bring a lot of attention from government authorities, especially the United States government. If your company is not part of these sectors, you are a target for them.

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

Recovery of Files Encrypted by BlackMatter Ransomware

Digital Recovery has developed a unique technology that can recover ransomware-encrypted files of any length, we call it Tracer.

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

We did not accept this fact and invested heavily in developing an appropriate technology for this, and after much investment and effort we finally succeeded in creating this technology. It has saved our customers a highly significant amount of money for their companies.

All our services follow the guidelines established by the LGDP (General Law of Data Protection), so that the recovery of encrypted data is done in a secure and discreet way. Besides following these guidelines, we also count on the confidentiality agreement (NDA).

See what we can do to recover ransomware files in practice, contact one of our specialists, and start the data recovery process now.

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 be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses 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 even 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.

Yes, attacks usually happen mainly on holidays and weekends during the early morning hours. These days are chosen because there are not many active users on the system, which prevents the attack from being discovered before the encryption is completed.

The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman]-2048 and AES [Advanced Encryption Standard] encryption.

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 specialized cybercrime departments that will investigate the attack. After that, check if your backups were affected, if they were, only a company specialized in data recovery can recover your files, this is the next step. Contact Digital Recovery who will assist you in the complete recovery of your files.

After first contacting us and sending the affected media we will diagnose the device to check the extent of the damage caused by the ransomware, with this we can project the duration of the process, and provide the budget to the customer. After the budget is approved by the customer, we start the recovery process, for this we have exclusive software that can, with the help of our specialists, reconstruct the data.
If the customer opts for remote recovery, instead of sending us the media, he/she will send the encrypted files to a virtual environment, which is totally safe, so that we can access them.
After the end of the process we will do a double check so that the customer can verify the integrity of the recovered files.
Payment is only made after delivery of the files and validation of the same by the client.
