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

Ransomware FiveHands

FiveHands Ransomware, also known as Hello Kitty ransomware, was discovered by CISA (Cybersecurity and Infrastructure Security Agency), a U.S. agency focused on cybersecurity, and its attacks have been going on since May 2020. The group uses the double extortion method, which in addition to blocking the files also threatens to leak them, this tactic is used to pressure the victim to pay the ransom as soon as possible.

In some cases, if the victim does not pay or respond quickly, they threaten a break-in to the company’s public website. The ransom payment is made in cryptocurrencies, the amount of the ransom varies depending on the size of the attacked company.

The initial access of the FiveHands ransomware is different from other ransomware, which attack victims through email campaigns, FiveHands uses VPN devices, this access allows them to generate a VPN profile and enter the victim’s target network, using the hostname and then deploy the ransomware thus initiating encryption.

The group became famous for attacking video game studio CD Projekt Red (producer of The Witcher and Cyberpunk 2077) in February this year. After the attack the group confirmed on the dark web that the information that was stolen from the studio had been sold to a third party, but this was never actually confirmed.

The attacks are usually aimed at Linux servers using virtual machines. After the invasion the ransomware encrypts the victim’s data, and together with pCloud synchronizes the files in the cloud, so that even if the victim shuts down the computer or the internet the group can extract the files to perform double extortion.

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.
