I hadn't really heard much about this but apparently four out of five results returned when asking Google for a 'bitcoin qr generator' lead to scam websites. The sites then generated a QR code that encodes an address controlled by the scammers instead of the one necessary for the user.
Apparently instead of scammers making their own fake QR codes they have a blockchain explorer API to generate the QR for their address.
This scam falls into the reported $4 billion of digital currency stolen in Ciphertrace AML report.

The popularity of cryptocurrency has boosted apparently,
however we cannot disregard this fact that scam schemes is taking advantage of this as well.
