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 after-effects in companies around the world.

A senior software developer at cybersecurity company 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 organization’s IT system and therefore greatly increases the likelihood that an organization 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 enough, the Cheers ransomware renames the files even before it encrypts them. This 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 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.

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.
