Hello. Unfortunately, I need to start our conversation with bad news for you. Around few months back I managed to get full access to all devices of yours, which are used by you on a daily basis to browse internet. Afterwards, I could initiate monitoring and tracking of all your activities on the internet. I am proud to share the sequence of how it happened: In the past I bought from hackers the access to various email accounts (today, that is rather a simple thing to do online). Clearly, it was not hard at all for me to log in to your email account ([snip]).
A week after that, I had already managed to effortlessly install Trojan virus to Operating Systems of all devices that are currently in your use, and as result gained access to your email.
Herbey, I believe that now you finally start realizing how I could easily remain unnoticed all this while until this very letter...
Well, there is still a way to settle this tricky situation in a peaceful manner: You will need to transfer $1380 USD to my account (refer to Bitcoin equivalent based on the exchange rate at the moment transfer), so once funds transfer is complete, I will straight away proceed with deleting all that dirty content from servers once and for all.
! Abstain from attempting to get in touch with police or any other security services. Moreover, don't even think of sharing this to you friends. Once I discover this (apparently, that is absolutely easy for me, taking in consideration that I have complete control over all systems you use) - kinky video will straight away be made public.
