Dear Ms.  ;
We compromised your devices and we have all your information related to your personal life and your adventures during travels (you know exactly what we mean). You have 24 hours to pay 50 USD, we do not want to expose you since we do not have any benefit doing troubles. We will delete everything related to you and leave you alone (sure 50 USD means nothing to you). If you want to contact the police you are free to do so and we are free to expose you too. We are not criminals, we just need some money, so be gentle and everything will pass safely for you. See how deep we know about you, if you want more we will email your advantures to your relatives:
Pay the 50 USD to XMR (if you face problems pay using Bitcoin) (find out in Google how to):
XMR: 46JJs5ttxR9jdNR2jmNiAbX5QtK3M9faBPPhh7WQwvrs8NLFpsagtZ3gnA6K6pSrm53JefbXGok6GTn7UexPHSBC2w2aN6j
Bitcoin: 3NQCHf924JYzU2LfziVpfrX9cvJGwTCmvi
You can buy XMR from https://localmonero.co/.
