Synology NAS Hacked by Ransomware

Synology NAS was developed by a company of the same name, Synology Inc. is a Taiwanese company specializing in network-attached storage devices, they are known for desktop models as DIskStation, FlashStation for flash models and RackStation for rack models.

A NAS system is a storage device, which can be connected to the local network. NAS is cheaper and provides the benefits of a local public cloud, allowing those who are authorised to access the files.

Ransomware is a malware whose main goal is the total or partial encryption of files, to start the encryption the ransomware needs to access the victim’s network, for this the groups use several approaches such as spam email campaigns, malicious websites, illicit programmes, brutal force attack, access through RDP ports among others.

In recent years groups have emerged specializing in NAS devices, among them is Synology, the fact that the NAS is connected directly to the Internet and centralize the storage of data made it the main target of attacks.

After the ransomware invades the operating system, it can move laterally changing backup routines and access computers with more privileges. The criminals’ target is always to take away all alternatives of restoring the system without a decryption key that is under the group’s power.

For this reason, backups are their main targets, and the groups use psychological pressure to make the victim see no other way out but to pay the ransom.

A ransom note is left on the desktop, in it the group directs the victim to contact the group through the .TOR browser, this note contains numerous threats should the victim choose to make the payment.

But remember that the biggest damage in these cases are the financial ones, the company may stop for weeks because of the data encryption. In view of this, it is necessary to know alternative solutions to paying the ransom, and the best of them is data recovery that can be done by a specialized company such as Digital Recovery.

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.
