Patelco Credit Union, a California-based not-for-profit organization with assets exceeding $9 billion, has disclosed a ransomware attack that led to the shutdown of several customer-facing banking systems. The attack occurred on June 29, and as a result, online banking, mobile app, and call center services are currently unavailable. Electronic transactions such as transfers, direct deposits, balance inquiries, and payments are also unavailable. Debit and credit card transactions are operational but in a limited capacity.
Members can still perform cash withdrawals from ATMs, which have not been impacted by the remediation effort. Patelco has engaged with third-party cybersecurity experts to investigate the incident and accelerate the recovery, but no date for return to normal operations has been given yet. The organization anticipates delays in customer service and apologizes in advance for the situation.
No ransomware groups have claimed responsibility for the attack at Patelco, so the perpetrators remain unknown. The firm has not commented on the possibility of customer data exposure yet, presumably because the investigation is still in its early phase.
