Hackers with suspected China ties breached MTA servers in April

Hackers with possible ties to the Chinese government breached three of the MTA’s computer systems earlier this year, transit officials said Wednesday.

The breach occurred on two separate days in the second week of April and continued unchecked until being discovered on April 20, officials said. Hackers did not access systems related to train operations, safety or customer or employee information, the MTA said. The authority “quickly and aggressively responded to this attack,” MTA Chief Technology Officer Rafail Portnoy said in a statement. An outside audit “found no evidence operational systems were impacted, no employee or customer information breached, no data loss and no changes to our vital systems,” Portnoy said.
