Patelco data breach: What happened?

Patelco suggested customers use ATMs in their larger Co-Op network, which has over 30,000 shared branch ATMs across the U.S. However, many customers still had trouble accessing their money.

CEO and President Erin Mendez emailed customers to explain the situation:

“Dear XXXX,

We are writing to let you know that on June 29, we experienced a serious security incident. This required us to shut down some of our day-to-day banking systems so that we can remediate the issue and contain the impact, including online banking, our mobile App, and our call center. Currently, electronic transactions such as transfers (including Zelle), direct deposit, balance inquiries, and payments are unavailable. Debit and credit card transactions function in a limited capacity.

Patelco branches, our call center and Live Chat will be open and ready to assist as much as they can during our regular business hours starting tomorrow, Monday July 1.

For cash withdrawals and deposits, you can access Patelco ATMs, including over 30,000 shared branch ATMs all over the country. Find your nearest branch and ATM (including hours of operation) at

This incident shows how important strong cybersecurity is for banks. As more banking moves online, the risks from cyberattacks increase. Patelco needs to learn from this breach by strengthening its security systems and being better prepared for future incidents.

Customers should also be aware of their bank’s security practices and push for more transparency and accountability. Both banks and customers need to stay alert and proactive in dealing with cyber threats, such as the Patelco data breach.
