Ransomware

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

QNAP NAS Attacked by Ransomware

QNAP NAS is a device developed by QNAP Systems, which is a Taiwanese corporation specializing in developing network attached storage devices such as NAS.

The NAS can be directly connected to the network users, in most cases, a NAS consists of multiple hard drives organized as a RAID system. This type of device is perfect for businesses that have a high flow of data.

Given these features provided by QNAP on their NAS devices, ransomware groups have been focusing their attacks on QNAP NAS. The groups that have been prominent with these attacks are QNAPCrypt and DeadBolt.

Ransomware is malware designed to encrypt all data stored on a system, blocking access to files and charging a high fee to release the decryption key.

To access the victim’s system the groups use numerous strategies such as virus-ridden websites, malicious emails, illicit programs, Phishing, brute force attacks, employee grooming, and perhaps most worryingly, using vulnerabilities in the QNAP NAS itself.

The DeadBolt ransomware claims to have found an hour 0 vulnerability, this name is given to vulnerabilities discovered that are unknown by its developers. And from what it seems, in fact this vulnerability is real.

QNAP itself has published an alert about the attacks made by the group, instructing its users not to connect the NAS directly to the Internet but to a Firewall for the protection of the device.

DeadBolt is selling the information about this vulnerability on the Dark Web for 50 Bitcoins, if this vulnerability becomes known to other groups, the ransomware attacks on QNAP NAS may increase sharply.

In case of successful ransomware attacks, all files and backups that are connected to the network will be encrypted, and the group will charge a high fee to decrypt the affected files.

Digital Recovery provides an option to paying the ransom, the recovery of data encrypted by ransomware. Through its solutions from Digital Recovery, files can be recovered and thus the company’s system restored. All this, without any kind of negotiation with the criminals.

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.

How to identify a ransomware attack?

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.

Is it possible to stop the encryption process?

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.

Is there a day and time when ransomware attacks are most prevalent?

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.

What is the encryption used by the hackers?

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.

What to do after a ransomware attack?

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.

How does the digital recovery process work?

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.
