A hacker broke into Istanbul public trasnportation monitors' systems, replacing the usual route information with the message “Ekbar was here,” early March 21.
Istanbul passengers were surprised when they saw the message on the monitors of buses and trains run by the Istanbul Electric Tram and Tunnel Company (İETT), the city's major transportation authority.
Meanwhile, the İETT's website was also not available to its users at 7:20 a.m. The error was shortly fixed and the website became available again around 9:00 a.m.
The IETT serves more than 14 million inhabitants in Istanbul.
