QR code scanning habit could be costing you money and data

QR codes are convenient but also a popular scam tool today. Just one wrong scan can cause users to have their accounts stolen or lose money.

QR codes are popping up everywhere, from restaurants to event tickets to product packaging.

Taking advantage of that convenience, bad guys can replace real QR codes with malicious codes to trick users.

With just one scan, users can be redirected to a fake website or installed a malicious application.

A prime example is a scam in San Francisco, where scammers left fake parking tickets on cars, with a QR code leading to a fake website impersonating the city's public transportation site, causing many people to pay bogus fines.

One case last year saw a scammer create a fake YouTube channel, live-streaming a deepfake video of Elon Musk with the promise of doubling any cryptocurrency sent to him. In the video , viewers simply scanned an on-screen QR code to participate in the “investment opportunity.”

The "quishing" trick in fake bank emails asking to scan a code to change your password is also very dangerous.

Users should carefully check the link that appears before clicking on it after scanning the QR code.

It's best to never scan codes from unknown sources, such as strange packages or unexpected messages.
