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

Ransomware Rever

Ransomware attacks have been on the rise these past few years, and new ransomware often emerges. This July, it was the case with Rever ransomware that has some important characteristics.

The main target of Rever ransomware is Synology NAS and Windows Server systems. After breaking in, most often done via unprotected RDP or malicious emails, the attackers encrypt the files defined as important.

The .rever extension is then added to the original name of the files present on the Synology NAS. On the other hand, files from Windows Server environments are given a random .<RANDOM{8}> extension, making it impossible to open files such as OpenOffice, MS Office, database, VM backup, VHD files, and others.

Among the recorded attacks, the most hit locations during invasions are the \Desktop\, \User_folders\ and the \%TEMP%%\ folder, which includes the login ID.

The attackers also use the Rever ransomware to generate a text file called “README_recovery.txt”, which is the equivalent of a ransom note. Victims can find the step-by-step necessary to contact the evildoers via the TOX CHAT instant messaging software and pay the ransom in Bitcoin.

In many cases, the group offers a free sample, decrypting a file as proof that they can do file restoration. But that is not a guarantee that the group will do the restoration after payment.

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.
