Ransomware Hotarus

Hotarus ransomware lists among the most profitable ransomware of the year 2021, Hotarus made an attack on Ecuador’s largest private bank and, claimed to have stolen numerous bank customer files.

The group released 6,500 personal files of the bank’s customers, such as user login, passwords, and card numbers. Although the bank claimed that the attack did not target their internal system, but a partner marketing company.

But this does not seem to be true, as the leaked files were under the care of the bank. The group claimed that they broke into the marketing company’s system, but found loopholes in their system that led to the bank’s servers, and they took advantage of this loophole by stealing and encrypting as many files as possible.

This attack is a clear, practical example of how ransomware behaves after a company’s system has been hacked. Ransomware moves laterally in search of files most valuable to the company, especially in integrated systems.

This is why it is vital to protect a company’s internal networks, such as segmentation. Segmentation serves to make each computer independent, so that if a computer is attacked the ransomware is isolated on that computer, encrypting only the files it contains.

This strategy decreases the ransomware’s field of action and reduces the chances of further damage to the company.

Segmentation is extremely important when talking about online backups, ransomware has developed to identify and encrypt all the files in the backup. Therefore, the backup needs to be isolated from the rest of the company’s network.

The best option is for the backup to be stored Offline, there are numerous Magnetic Tape options for this purpose.

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.
