A cyberattack targeting the Santa Clara Valley Transportation Authority last weekend has forced a days-long shutdown of many of the agency’s computer systems.
VTA officials say they believe they have contained the attack, but key systems remained offline Thursday.
The authority is still trying to determine whether any personal information of customers or employees was compromised, spokeswoman Stacey Hendler Ross said.
Buses and light rail trains have continued running, Hendler Ross said, although efforts to contain the hack are affecting functions such as real-time arrival information and VTA employee email.
“Our priority in this situation was to proactively shutdown technology systems to contain the event,” Hendler Ross wrote in a statement. “Teams have been working around the clock to bring back priority systems.”
She said that VTA “will move quickly to notify the appropriate parties” if it determines there was a breach of any personal data.
Hendler Ross said VTA is now working with law enforcement to investigate the attack; she did not know where the hack originated, or what kind of attack it was.
