A new version of Ryuk ransomware is equipped with an additional worm-like capability to spread itself around infected networks, potentially making it even more dangerous than it was before.
Ryuk is one of the most prolific forms of ransomware, with its cyber-criminal operators thought to have made over $150 million in Bitcoin ransom payments from victim organisations around the world.
Like other forms of ransomware, Ryuk encrypts a network, rendering systems useless and the cyber criminals behind the attack demand a payment in exchange for the decryption key. This demand can stretch into millions of dollars.
