Data leaks are old news so for now, delete the extortion email and change you current passwords. As to the claim they installed some app on your PC, that's what they claim.
Head to Bleedingcomputer.com and tell the story and ask what you should scan with.
Only the newest users fall for this.
Hi, I found an email in my junk folder addressed to me by name. The subject contained one of my usernames & a password I recognised.
The message said that a program had been downloaded to my laptop when I had visited a certain type of website. This program activated the webcam on my PC & filmed me visting this website.
It then went on to instruct me to deposit $1000 into a cryptocurrency account. If I did not comply the said video would be sent to everyone in my contacts list.
This was a complete bluff, firstly I did not visit the website & secondly the webcam on my laptop is disconected in device manager.
However the sender has a user name & password of mine & that is scary. I went through my little book of passwords & found that username/password was for an old G-mail account that I never used & it had no names in the contact list.
The real scary part is the extortion email was sent to one of my main email accounts.
How could this have happened?
