TikToker Marcus Hutchins explains how he picked up a device for 'a few hundred dollars' called 'Proxmark', which can 'clone anything to 'HID cards to hotel keys'.

What the heck is a Proxmark, you might ask?

Well, according to proxmark.com: "The Proxmark is an RFID swiss-army tool, allowing for both high and low-level interactions with the vast majority of RFID tags and systems worldwide."

Marcus's TikTok bio reads: "Ex hacker, current felon. Teaching Cybersecurity."

"You probably shouldn't leave access cards lying around," he said.

He showcases that, within seconds, his Proxmark reads the data of his key card.

Marcus added: "The best part is that it'll even through a coat pocket.

"Now, obviously this whole set-up with the laptop is a bit inconspicuous so you can actually put it in 'mobile mode' and it'll work from a battery pack.

"Holding down the button will start to scan and when it comes into contact with a key it will save the data.

He attaches the battery pack to his Proxmark and places it in his back pockets.

Next, he connects an antenna to a really long USB cable and puts it down his sleeve, plugging it into the back of his Proxmark.

"[Now] I've got the data off the card I can create an identical key but it's a lot more fun to use the proxmark itself as a key."

The viral video was posted on 15 August and has since racked up 4.5 million views and 486,000 likes.

One user, incredibly, pointed out: "You could steal a Tesla theoretically with this since they use a card."

A second user added: "I can't decide if this is awesome or terrifying."

Whilst a final user joked: "I'm so grateful you're teaching people how to be scammers" to which Marcus replied: "As I have already said: this isn't a tutorial. It doesn't explain any of how to do it."

Well, we know we definitely won't be leaving any cards lying around unattended from now on!
