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

Gwisin Ransomware

Gwisin ransomware has been increasing the number of its attacks around the world. Asian countries, such as Korea, have been the target of an unprecedented wave of Gwisin ransomware attacks.

Unlike other ransomware, Gwisin chooses and studies its victims very carefully. Each of them unknowingly undergoes a detailed analysis before being attacked.

Gwisin ransomware is distributed in MSI installation file format and then the means of spreading the virus becomes customized for each victim. This is exactly why it takes time to study the target before the attack.

Being able to infect both Windows and Linux operating systems, Gwisin has spooked experts by its very high infection speed. The support for file encryption even without safe mode has also caught the attention of experts.

Once the encryption process is complete, the infected files are given an extension with the company’s own name.

The operatives then leave a ransom note called “Restore-My-Files.txt” in the environment. In the same file the victim will find the step-by-step instructions for contacting the group responsible for the attack and recovering his or her data. The amount of the ransom will also be mentioned, usually ranging around 0.005BTC (approximately 120.00$USD).

Although many victims will agree to pay the ransom, this is not recommended practice as hackers are criminals who offer no real guarantees for the return of stolen data.

After suffering an attack, a company or institution needs to be very well monitored. Digital Recovery can be counted on for this.

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.

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.
