Yesterday I received an email that's different from the usual spam/hoax that sometimes sneaks past my email provider's spam filter. It threatened to spread a video of me playing with myself while watching porn on my computer unless I pay $500 in bitcoins. It gives me a deadline which is some time tomorrow. The threat is accompanied by lots of stuff about how he's in control of my computer using a trojan and warnings against going for help.
It's impossible for anyone to have that kind of video because what the author claims I did simply never happened. So at the moment I'm inclined to dismiss it as a bluff. However, I'd like to know if anyone here has ever received this kind of mail and if it's likely to be followed by more serious attacks.
One thing did happen afterwards that may or may not be a coincidence: I clicked on the AV (Avira Free) icon in the taskbar and got a pop-up message saying "Revocation information for the security certificate for this site is not available. Do you want to proceed? - Yes/No/View certificate. When I clicked the 'View certificate' button, it says that it's issued to bs.yandex.ru
Do I need to be concerned? I mean about this particular threat as opposed to the general need to be vigilant? Do you advise reinstalling my whole OS drive? I can do that without too much trouble from a ghost backup.
