Jim Browning got a look into a Kolkata call center via one of the scammers’ insecure machines: “You’re looking at the webcam of a scammer named Deva ██████. He’s currently uploading the phone numbers of people who will be his next potential victims. All are numbers of people who have previously fallen victim to a popup scam.”

These guys are a particularly nasty group from Kolkata in India. They run a refund scam and this video shows what their call center looks like, how they operate, who and where they are. I’ve sent a link to the unblurred version of this video to the Kolkata Cyber Police (for all the good that it will do).
