  • dubious link in spam emails leading to the virus installer
    online free hosting resources;
  • using illegal peer-to-peer (P2P) resources for downloading pirated software.

The Nusm Ransomware will scan the data on the user’s system to locate the files targeted for encryption. Then, the Nusm Ransomware will trigger its encryption process and lock all the targeted data. When the Nusm Ransomware locks a file, it also alters its name by appending an additional extension – ‘.Nusm.’ For example, a file that was called ‘1.jpg’ previous to the attack will be renamed to ‘1.jpg.nusm’ after the encryption process is through.
