In the software of the router, through which you went online, was a vulnerability. I used it... If you interested you can read about it: CVE-2019-1663 - a vulnerability in the web-based management interface of the Cisco routers. I just hacked this router and placed my malicious code on it. When you went online, my trojan was installed on the OS of your device. After that, I made a full backup of your disk (I have all your address book, history of viewing sites, all files, phone numbers and addresses of all your contacts). A month ago, I wanted to lock your device and ask for a not big amount of btc to unlock. But I looked at the sites that you regularly visit, and I was shocked by what I saw!!! I'm talk you about sites for adults.
