A new scam is underway on YouTube that uses videos to promote a tool that can allegedly generate the private key for a bitcoin address. The attackers then claim this key would then allow you to gain access to the bitcoins stored in the bitcoin address, when in reality the victims will be infected with a password and data stealing Trojan. The Trojan can steal a variety of information and passwords from a computer, including copying the victim’s clipboard, recording over the webcam, and stealing files from the victim. If you have been infected with this Trojan, you should immediately change all passwords for your financial accounts, web sites, chat services such as Discord, and gaming services.
