I got the following email twice:
_x000D_
Hello, _x000D_
_x000D_
I am a spyware software developer. Your account has been hacked by me in the summer of 2018. _x000D_
_x000D_
I understand that it is hard to believe, but here is my evidence (I sent you this email from your account). _x000D_
_x000D_
The hacking was carried out using a hardware vulnerability through which you went online (Cisco router, vulnerability CVE-2018-0296). _x000D_
_x000D_
I went around the security system in the router, ....etc etc.... mail and sms to all your contacts with compromising material. _x000D_
_x000D_
I advise you to remain prudent and not engage in nonsense (all files on my server). _x000D_
_x000D_
Good luck!
