Los Angeles Metro signs may have been seized by online activists earlier this week, with the signs typically meant to display wait times and other messages instead displaying a threatening message.
Photos shared with KTLA on Monday showed one of the digital readout boards at a bus stop at 6th Street and Vermont Avenue displaying a message that read, “Emergency Warning. Leave Immediately. Suicide Bomb Danger.”
The message was signed using a social media outlet that some media outlets have reported is a Turkish hacking group that may also be responsible for hijacking public advertising systems in Multiple airports In North America.
Los Angeles Metro officials said digital signage boards at several bus stops were confiscated. The violent messages could be tracked through a third-party content management system called Papercast, which he said was “hacked.”
“The unauthorized messages have since been removed. LA Metro is working with Papercast, the third-party vendor, to identify the source of the intrusion and address it.”
