I am a spyware software developer. Your account has been hacked by me in the summer of 2018.
I understand that it is hard to believe, but here is my evidence (I sent you this email from your account).
The hacking was carried out using a hardware vulnerability through which you went online (Cisco router, vulnerability CVE-2018-0296).
I went around the security system in the router, installed an exploit there. When you went online, my exploit downloaded my malicious code (rootkit) to your device. This is driver software, I constantly updated it, so your antivirus is silent all time.
Blablabla it goes on for a while and asks to pay them 996 usd in bitcoins
