PITTSBURGH — (WPXI) – An internet outage that delayed T rail cars and threw several of Pittsburgh Regional Transit’s systems offline last week was related to a ransomware attack. Adam Brandolph, spokesperson for PRT, said the attack was first detected on Thursday, Dec. 19. Upon discovering the incident, PRT immediately launched an investigation, activated its Cyber Incident Response Team, notified law enforcement and engaged nationally recognized third-party cybersecurity and data forensics experts. While rail service experienced temporary disruptions on Thursday morning, transit services are currently operating as normal, Brandolph said. However, some other rider services remain negatively impacted, including PRT’s Customer Service Center, which is temporarily unable to accept or process Senior and Kid’s ConnectCards. PRT will continue to provide updates as appropriate, Brandolph said.
