The Washington State Office of the Attorney General disclosed a data breach at Centennial Bank, occurring between April 6–7, 2023, but reported on April 19, 2024. Unauthorized actors gained access to the bank’s computer network, compromising the personal details of 3,044 Washington residents. The exposed data included highly sensitive information such as names, Social Security numbers, financial records, and driver’s license numbers. The breach poses significant risks, including identity theft, financial fraud, and long-term reputational damage for both the bank and affected individuals. Given the nature of the stolen data—particularly Social Security and financial information—the incident falls under a high-severity category, as such details are prime targets for cybercriminals. The delayed disclosure (nearly a year later) may further exacerbate trust issues among customers and regulators. While the exact method of intrusion remains undisclosed, the scale and sensitivity of the leaked data suggest a targeted cyber intrusion, likely aimed at exploiting personal and financial records for malicious purposes. The bank is now obligated to implement remediation measures, including credit monitoring for victims, system audits, and enhanced security protocols to prevent future incidents.
