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 publicized attack was on CD Projekt Red, the 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 defense system known as SonicWall.

The FBI reported that in addition to encrypting the machine, the group puts pressure on the victim, giving them a deadline to pay, 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 paralyzed the system for 3 days and the company’s staff 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 the data is encrypted the extension “.kitty” or “.crypted” 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 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.

Yes, attacks usually happen mainly on holidays and weekends during the early morning hours. These days are chosen because there are not many active users on the system, which prevents the attack from being discovered before the encryption is completed.
