A scam that threatens to expose porn-viewing habits unless a Bitcoin ransom is paid is doing the rounds again.
Detective Senior Sergeant Callum McNeill says Waitemata Police are investigating a number of recent reports of the email extortion scam which first surfaced 2018.
The scammers send an email to victims telling them their computer has been hacked and a video has been taken through their webcam showing that they've looked at pornographic websites.
The scammers threaten to send the video to the victim's friends and family unless they are paid $1,900 in bitcoins.
"Unfortunately some of the victims have been so concerned that a video of themselves would be leaked that they have paid money to the scammers.
