Insecure App Exposed Billboard Lights to Hacker Attacks
Reported by securityweek.com
Malicious hackers and pranksters could have hijacked billboard lighting systems by exploiting vulnerabilities found in a service provider’s mobile application.
While trying to find out how the lights on highway billboard signs are controlled, security researcher Randy Westergren came across SmartLink , a cellular controller system designed for remotely controlling and monitoring billboard lights. SmartLink, which has been installed more than 50,000 times, is provided by OutdoorLink, a company that specializes in helping outdoor advertising companies monitor and manage energy usage.
