I am a spyware software developer. Your account has been hacked by me in the summer of 2019. The hacking was carried out using a hardware vulnerability through which you went online (Cisco router, vulnerability CVE-2019-12643). When you went online, my exploit downloaded my malicious code (rootkit) to your device. Since then I have been following you (I can connect to your device via the VNC protocol). I also have access to the camera on your device, and I periodically take photos and videos with you. Transfer $907 to my Bitcoin cryptocurrency wallet: 1CDKLgab6xUnAwP5q5x3jdDy8978Bt2iCZ. Since opening this letter you have 48 hours. If funds not will be received, after the specified time has elapsed, the disk of your device will be formatted, and from my server will automatically send email and sms to all your contacts with compromising material.
