Trico Bancshares in Chico, Calif., is dealing with a cybersecurity incident.
The $9.9 billion-asset company disclosed in a regulatory filing that it recently shut down its networked systems after detecting unusual activity.
Several of Trico’s internal bank systems are offline, including email, telephones and its customer service/call center. The company said it is working to restore the services as quickly as possible.
Trico said it is trying to determine the scope of the event, including the impact to any data or information maintained on internal bank systems.
The company said that its customers’ balances are unaffected and housed on a secure system that is separate from the network that was breached.
