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

Night Sky Ransomware

Night Sky Ransomware recently emerged, on December 28, 2021 to be exact, making attacks on two large companies, one of which is TGC (Tokyo Computer Service) one of Japan’s largest computer companies and AKIJ Group, one of the largest industrial conglomerates in Blangadesh.

TGC’s servers that were hit by 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 uses strategies to pressure the victim to pay the ransom as soon as possible, these tactics are used as psychological pressure so that the victim sees no way out other than paying the ransom. But, the truth is that paying the ransom is not the only way out, there are companies that specialize in recovering files encrypted by ransomware, among them is Digital Recovery. 

Payment is always discouraged by government authorities, ransom payments fund new attacks. There is no guarantee that after payment the key will actually be released. Therefore, never opt for payment. 

Night Sky ransomware uses a combination of AES and RSA algorithms for data encryption, this combination is extremely strong and complex. The extension .nightsky is added to all encrypted files. 

Night Sky spreads through unsecured RDP setups, 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 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.
