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

Hellokitty ransomware

The HelloKitty ransomware, also known as FiveHands, has become quite relevant, to the point of drawing the attention of CISA and the FBI.

The group was first spotted in December 2020 and remains active to this day. Their biggest publicised attack was on CD Projekt Red, an electronic game company known for “The Witcher” franchise.

HelloKitty uses the Ransomware as a Service (RaaS) tactic. Which allows ransomware to be bought and sold to anyone, thus making the group’s reach greater.

In most attacks systems are hacked from breaches caused by the vulnerability of the defence system known as SonicWall.

The FBI disclosed that besides encrypting the machine, the group puts pressure on the victim, giving them a deadline to make the payment. If the deadline expires, the information will be leaked or sold to third parties.

For each target, the hackers make an assessment to determine a ransom amount, however all payments must be made with Bitcoin.

In December 2020 the featured victim was the Brazilian company Companhia Energética de Minas Gerais (CEMIG). The attack paralysed the system for 3 days and the company’s team chose not to negotiate with the group but to make a backup of all the information.

Thanks to this invasion, we had access to the encryption key that HelloKitty uses, the RSA-1024. A very common encryption algorithm among ransomware. After data is encrypted the “.kitty” or “.crypted” extension is added to each infected file.

HelloKitty ransomware came from the same family as Scarab ransomware. And besides FiveHands it has other name variations like:

  • KittyCrypt
  • Kitty Ransomware

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.
