What is Ransomware Ryuk? How to prevent it?

How does Ryuk attack the victims?

Ransomware Ryuk works by encrypting important data available on the network. The attackers then provide the user with a decryption key in exchange for the ransom (in the form of a cryptocurrency).

Attackers often aim to hack as many machines as possible, but the Ryuk ransomware works in a unique way. The way hackers prepare for an attack makes it rare and unique in nature.

The Trojan trickbot is installed on the system for the first time. Basically, the trojan is intended to stay on the system for a long time. The organization's network is mapped in the next step and attackers can now steal credentials by compromising the network.

Now, one of two standard ransomware notes will be sent to the victim as soon as the system is compromised. The targeted company is required to pay a specific ransom amount in Bitcoin to decrypt the system.

The text also threatens the victim to destroy all files, if they don't pay the ransom. Finally, a contact email and a Bitcoin wallet address will be shared with the victims.

If the victim ignores the first ransom notice, a second ransom notice will be sent to threaten them of the consequences. It's worth mentioning that the new ransomware is endangering users and could force them to pay a ransom. The estimated payable amount is approximately $ 224,000.

The attacker needs to know the financial condition of the target network before executing the attack. The main reason behind bringing Ryuk into target systems is to identify the most important computers and data sets.

Experts still do not have any idea of Ryuk's origin. Some attackers claim it came from Russia, while others claim that Ryuk is of Korean origin.

How can I protect my PC against Ryuk attacks?

Several notable attacks have been reported in the past few months. Users should be trained to use email protection platforms that can spot malicious spam on the first try.
