This newest version of Ransomware hides itself inside a fake invoice attached to an email.
This version of Spora -- distributed during a 48-hour campaign that began on August 20 -- is spread by a phishing campaign that sends email with an attached Word document claiming to be an invoice.
In order to see the contents of the file, the user is asked to enable a Windows Script File, which allows the document to drop its malicious payload. It's the first time Spora has been embedded in a document, rather than pulled from a web site/server.
If your computer displays signs of Ransomware infection. Turn it off - disconnect it from the Network/Internet. Call Tech Support.
