LED electronic boards of some schools have been edited with inappropriate content.

On the afternoon of November 21, the LED electronic boards at Cam Che Kindergarten and Cam Che Secondary School (Thanh Ha, Hai Duong) were hacked by bad guys, who changed the displayed content to post online game advertisements that were very offensive and not suitable for the educational environment.

It is known that after the incident, the schools disconnected the power system connected to the LED electronic boards and reported to the authorities to investigate and find the person who edited it. The inappropriate content on the LED electronic boards has been fixed.

Currently, LED electronic boards appear in many places in agencies, units, businesses, and public places. If not strictly managed, bad guys can break into the system, edit it into bad, toxic, offensive content, affecting propaganda work and security and order. Individuals and organizations using LED electronic boards need to increase inspection and review of wifi passwords in use, and improve security to avoid bad guys from breaking in and changing content.
