Indonesian police said a man arrested for broadcasting porn on an electronic billboard in the country’s capital gained access to the system after it displayed its log-on credentials. Jakarta Police Chief Muhammad Iriawan said the suspect, 24-year-old Samudera Al Hakam Ralial, admitted he hacked the IT system of the billboard operator. The movie was displayed for a few minutes on the giant video screen in southern Jakarta on Friday. Iriawan said Samudera had passed by the billboard and saw it was displaying user credentials and other information. He then logged in to system from his office but claims he didn’t realise a pornographic website he viewed was uploaded to the billboard.
