Back in August when US Speaker of the House Nancy Pelosi visited Taiwan, electronic signage boards in Taiwan train stations and 7-Eleven are hacked and defaced with anti-Pelosi messages. It is widely believed the communist Chinese is behind these for their political view against an independent Taiwan.
Latest investigations revealed the billboards are made in China, and either there are backdoors in its software or first hand vulnerabilities known to the mainland Chinese hackers made it possible. Taiwan is under work to enact new laws prohibiting use of Chinese made electronic and telco products on critical infrastructure.
