Context: Locky is ransomware malware released in 2016.  Superly active in 2017, it is delivered by email (that was allegedly an invoice requiring payment) with an attached Microsoft Word document that contains malicious macros.  When the user opens the document, it appears to be full of garbage, and it includes the phrase "Enable macro if data encoding is incorrect," a social engineering technique.  If the user does enable macros, the macros then save and run a binary file that downloads the "actual" encryption trojan, which will encrypt all files that match particular extensions.  Filenames are converted to a unique 16 letter and number combination with the . locky file extension.  After encryption, a message (displayed on the user's desktop) instructs them to download the Tor browser and visit a specific criminal-operated Web site for further information.  The Web site contain instructions that demand a payment of between 0.5 and 1 bitcoin (one bitcoin varies in value between 500-1000 Euros via a bitcoin exchange).  Since the criminals possess the private key and the remote servers are controlled by them, the victims are motivated to pay to decrypt their files.
