A new sextortion scam is underway that claims to be from the ChaosCC hacker group who states they infected the recipient’s computer with a Trojan that videoed them on adult web sites.
If you received this email, it is important to know from the beginning that this is a scam and that no hacker group has infected your computer or videoed you while using adult sites.
Instead this is just a scam, commonly called sextortion, that tries to scare you into thinking that you are videoed while doing something you would like to keep private so that you will pay them an extortion demand.
