Nefilim Ransomware

Nefilim ransomware first appeared in March 2020 and since then there have been numerous records of attacks by this group. The main targets of the group are companies with a turnover of over $1 billion.

This type of strategy is called “Big Game Hunting”, some ransomware is developed specifically to target these companies, but that doesn’t take away the fact that smaller companies will also be attacked by them.

The Nefilim ransomware is famous for using exposed RDP ports, this is the operating system’s own port for remote access. The group takes advantage of this port to access the system.

After breaking into the system, the ransomware starts moving laterally in search of better credentials to access servers with more valuable files. Upon finding these files, they are copied and extracted to the criminals’ server, and after extraction the original data is encrypted.

This data is used for double extortion, this tactic involves copying the files and extracting them and encrypting the original ones stored. The encryption will paralyze the operation of the company, which is the first tactic implemented, if this does not make the company pay the ransom, the stolen data is released on the group’s leak site.

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.
