It’s been revealed that hackers infiltrated computer systems for the Metropolitan Transportation Authority in New York in April.
The hacking saga set off a scramble to counter any potential cyberattack against the largest transit system in North America.
The agency received an alert from the FBI and other federal agencies saying that three of its 18 computer systems were put at risk.
A forensic analysis found that no sensitive information was stolen.
“Importantly, the MTA’s existing multi-layered security systems worked as designed, preventing spread of the attack and we continue to strengthen these comprehensive systems and remain vigilant as cyberattacks are a growing global threat,” said Rafail Portnoy, the MTA’s chief technology officer.
The cyberattack was first reported on Wednesday by The New York Times, citing an internal document that was not made public.
It was suspected that the breach had links to China.
The rail service is used by millions of people each day.
A statement from the MTA did not mention China but is continuing to investigate.
