Hacker Builds a QR Code Generator

Nowhere is the distinction between the haves and have-nots more apparent than when waiting for a flight at the airport. But it turns out you might not need an actual first class ticket to get into a swanky airport lounge—just a custom Android app that spits out a boarding pass-spoofing QR code. Przemek Jaroszewski is the head of Poland’s Computer Emergency Response Team and a frequent flyer with gold status. When he wasn’t able to gain access to the lounge at Warsaw’s airport due to an error with an automated boarding pass reader, he created a simple Android app that generates a valid QR code based on fake credentials he inputs.
