Blackmail by malicious email.
A couple of days ago my husband received an email from someone who claimed to have an explicit video of him.
The emailer addressed my husband by name, included a password he has used in the past, and meandered on to the real point of the exercise, which was to demand money. He had 24 hours to pay, then after that the video would be sent to all my husband's contacts.
The blackmailer explained that the money should be sent by Bitcoin, and there followed a description of how one could obtain them.
Tick-tock. Time is ticking.
This is part of a new scam. If you receive such an email do not respond to it. Do not panic.
The police advise that you should change all online passwords and ensure that your computer security anti-malware and anti-virus software is up to date.
Do not pay a ransom.
Contact the police, or report it anonymously to Crimestoppers.
(Of course we all know this already, but it is always worth a quick reminder!)
