This ransomware can stop you from using your PC or accessing your data. It might ask you to pay money to a malicious hacker.

Notably, this ransomware has worm capability, which means that it can spread to other computers in the network.

We have seen it being distributed via email either as a document with malicious macro codes or as an HTML application (HTA) packaged in a .zip file.
