Using a principle of persistence in the registry and combating various kinds of antivirus tools, Ryuk ransomware is a pretty formidable version of ransomware technology.

It uses RSA and AES encryption algorithms with three keys.

The Ryuk ransomware attack is credited to an electronic crime group called Wizard Spider. Experts suggest that Wizard Spider engages in what’s called “big game hunting” – infiltrating large corporate or government networks to affect a Ryuk ransomware attack that will be significant and lucrative. Ransoms are typically collected in Bitcoin.
