Night Sky Ransomware

Night Sky Ransomware has recently emerged, more exactly on December 28, 2021, making attacks on two large companies, one of them is TGC (Tokyo Computer Service) one of the largest computer companies in Japan and AKIJ Group, one of the largest industrial conglomerates in Blangadesh.

TGC’s servers that were hit by the ransomware contained employee data and other confidential files. According to the group, all the files were encrypted and a portion extracted to be used as blackmail.

Night Sky works in a way we’ve seen in other groups, working as follows, if the victim contacts within 3 days of encryption the ransom amount drops considerably. If the company is unwilling to comply with the group’s requests, the stolen data is leaked on the group’s website.

If there is no communication with the group after a week, the communication account is deactivated, each company attacked has a specific means of communication, usually, communications are made via email (nomedaempresa@nightsky.cyou).

This ransomware encrypts data from compromised corporate computers using a combination of AES + RSA algorithms and demands a ransom in BTC (Bitcoin) for the decryption key to be released.

Night Sky ransomware spreads via unsecured RDP configurations, spam and malicious email attachments, phishing, fake downloads, botnets, exploits, malicious ads, web injection, fake updates, repackaged and infected installers.

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.
