Hi, Let me introduce myself to you first of all - Im a professional hacker programmer. Unfortunately, you became my next victim, who I just hacked into the device and its operating system. Ive been watching you for several months. Simply put, while you were visiting your favorite erotic websites, I implemented a virus on your device. If you have never encountered a situation of this type, I will try to explain everything in detail. I gained full access and control over your device thanks to the Trojan horse.
