Email scam threatens to release video of people watching pornography if they don't pay bitcoin ransom
People are being sent horrifying messages threatening to post video of their most intimate moments on the internet.
What's more, the messages are shockingly believable: they appear to include secret information about the recipient that suggests the threats are real.
But in fact the messages are a scam. And they seem to be relying on the vast number of stolen passwords that are available across the internet.
The messages always begin with the most convincing part of the email: the claim that the person sending it has your password, which is included in the message itself. After that, it begins with a series of threats and demand for a ransom.
"I'm going to cut to the chase," the message reads. "You don't know anything about me whereas I now know a lot about you and you are probably thinking why are you receiving this mail, right?"
