FiveHands Ransomware

FiveHands ransomware, also known as Hello Kitty ransomware, was discovered by CISA (Cybersecurity and Infrastructure Security Agency), the US cybersecurity agency, and has been under attack 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 does not respond quickly, they threaten a break-in to the company’s public website. The ransom payment is made in cryptocurrencies, the ransom amount varies depending on the size of the company attacked.

The initial access of 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 destination 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 games) 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 turns off 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 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.
