+| 2019-07-17 | [Budapesti Közlekedési Központ (BKK)](https://bkk.hu) | Unknown 18 Year Old | Transit System Security | An unknown 18 year old was arrested in Hungary, for reporting a "shamefully stupid bug" in the new Budapest e-Ticket system. As a result of the arrest, thousands of 1-star reviews were left on the T-Systems (T-Mobile) and the BKK Facebook pages. The NFC/Smart Card system was apparently trivial to defeat for the unknown 18 year old security researcher. A number of flaws were reported, including passwords being emailed in plain text when asking for a password reminder, an IDOR allowing accessing the data of other users by manipulating the UR, the ability to clone tickets, the ability to change the price of tickets, and the admin password being "adminadmin". [Read an archive summary of the research on marai.me](https://web.archive.org/web/20200202080209/https://blog.marai.me/2017/07/24/18-year-old-arrested-bkk-tsystems-e-ticket/). After arresting the innocent security researcher, the story went viral, and resulted in T-Systems Hungary hosting a press conference 4 days later, and that the researcher had conducted an "illegal hacking attempt", yet reported the bug to the vendor. The BKK CEO told the press that they didn't receive the original report from the security researcher, because he sent it to the wrong email address, which this fact was completely debunked with a screenshot from the researcher. The original research appeared to have been released on Facebook, but a copy of the FB message can be [seen here](https://www.ibtimes.co.uk/dont-shoot-messenger-teenager-arrested-showing-security-flaw-hungarian-transport-system-1632472). A 500 person protest was subsequently held on Monday 24th July 2017 [Video](https://index.hu/video/2017/07/24/tuntetes_bkk_bkv_hacker_hekker/). "It is not clear whether any further legal action [was] taken against the young man." |
