Ransomware
If your files have been encrypted, we accept the challenge of analyzing your case.

Ransomware ALPHV BlackCat

The ALPHV BlackCat ransomware is the newest group that has drawn attention for having the most advanced malware in years. The group was only the third group to be able to write their strain in Rust language, this language is more secure and reliable than the ones used by the other ransomware groups, which use C and C++ language.

The group is still quite new, but already shows great potential to reach the same level as the REvil ransomware Sodinokibi and Darkside have reached. BlackCat uses the tactic of RaaS (Ransomware as a Service), the group has been offering its malware on Dark Web forums.

The ALPHV ransomware is designed to attack Windows, Linux and VMWare ESXi operating systems. Few groups have achieved this feat.

In addition to all these features, the ransomware moves laterally through a company’s internal network, disabling all company protections, and then installs copies of itself on multiple computers to reach as many files as possible.

The group disclosed in a forum that its encryption can be done in four different ways, which are:

  • Full – complete encryption of the file. The most secure and slowest.
  • Fast – encryption of the first N megabytes. Not recommended for use, the most insecure solution possible, but the fastest.
  • DotPattern – encryption of N megabytes by M-step. If set incorrectly, Fast can work worse in both speed and cryptographic strength.
  • Auto – Depending on the type and size of the file, the cabinet (on both Windows and * nix / ESXi) chooses the best strategy (in terms of speed / security) to process the files.

This shows how serious and advanced this group is compared to other groups. Besides the RaaS Tactic, the group also uses double extortion, which consists of encrypting and extracting files that will be used for blackmail, if the victim does not pay the ransom imposed by the group, the files will be leaked on a website created specifically for the victim company.

Recover Files Encrypted by ALPHV BlackCat Ransomware

The ALPHV BlackCat ransomware has shown itself to be one of the most worrisome groups in the near future, even though they do not have major attacks today, but from everything they have shown their destructive ability is very large.

The good news is that there are companies, such as Digital Recovery, with the ability and technology to recover data encrypted by ransomware.

This type of resource does not solve all of the consequences of the attack, but it dramatically reduces the damage that could be caused by not having access to the data. This type of resource is ideal for companies that need to have access to their files available for full operation.

In this scenario, Digital Recovery has developed technologies capable of recovering data encrypted by virtually any storage device such as HDDs, SSDs, Databases, Storages, RAID systems, Virtual Machines and others.

We have developed exclusive processes that are customized to meet the real needs of each client, all these processes are supported by a Non-Disclosure Agreement (NDA). The recovery is done in a totally secure environment.

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.

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.

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.
