Over 45,000 users have left one-star reviews on a company’s Facebook page after the business reported a security researcher to police and had him arrested in the middle of the night instead of fixing a reported bug. The arrest took place this week in Hungary after an 18-year-old found a flaw in the online ticket-selling system of Budapesti Közlekedési Központ, Budapest’s public transportation authority. The young man discovered that he could access BKK’s website, press F12 to enter the browser’s developer tools mode, and modify the page’s source code to alter a ticket’s price. Because there was no client or server-side validation put in place, the BKK system accepted the operation and issued a ticket at a smaller price…
The teenager — who didn’t want his name revealed — reported the issue to BKK, but the organization chose to contact the police and file a complaint, accusing the young man of hacking their systems… BKK management made a fatal mistake when they brazenly boasted in a press conference about catching the hacker and declaring their systems “secure.” Since then, other security flaws in BKK’s system have surfaced on Twitter. As details of the case emerged, public outrage grew against BKK and its manager Kálmán Dabóczi, especially after it was revealed that BKK was paying around $1 million per year for maintenance of its IT systems, hacked in such a ludicrously simple manner.
