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

Cheers Ransomware

The Cheers ransomware, even with only a short time of activity, has amassed several victims around the world, drawing attention.

Cheers has focused its efforts on unprotected virtual systems, such as VMware ESXi environments. This is not the first time that VMware servers have been prime targets for ransomware attacks.

Groups such as LockBit or HiveLeaks have acted in this way before and generated many serious aftershocks in companies around the world.

A senior software developer at cyber security firm nVisium claimed that an ESXi server “is much more than just a server”.

He also explained that: ”Its ability to host multiple virtual machines increases its importance within an organisation’s IT system and therefore greatly increases the likelihood that an organisation will pay the ransom to restore its servers.”

Once the VMware ESXi server has been hacked, the attackers launch the Cheers ransomware into the environment. The malware takes care of monitoring and quantifying all connected virtual machines (VMs) and then shuts them down.

From that point on, the Cheers ransomware begins encryption, placing importance on .log, .vmdk, .vmem, .vswp and .vmsn files. These types of files are considered valuable in the eyes of the victim and consequently become valuable in the eyes of the attackers.

Interestingly, Cheers ransomware renames files even before encrypting them. That way, if access permission has not been granted the actual encryption will not take place.

The ransomware will leave ransom notes in each folder while scanning the directories containing the data to be encrypted. The ransom notes will be named “How To Restore Your Files.txt”.

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.
