"55,000 Impacted by Cyberattack on California School Association"

The Association of California School Administrators (ACSA) recently started informing nearly 55,000 individuals that their information may have been compromised in a cyberattack. ACSA describes itself as the largest umbrella association for school leaders in the United States, serving more than 17,000 California educators, including superintendents, principals, vice-principals, and classified managers. ACSA says it discovered on September 24, 2023, that some files in its environment had been encrypted. An investigation revealed that a threat actor had gained access to ACSA systems between September 23 and 24, and they accessed and possibly exfiltrated certain types of information. ACSA noted that the exposed files contained information such as names, addresses, dates of birth, Social Security numbers, driver's license numbers, payment card information, medical information, health insurance information, tax IDs, student report cards and test scores, employer-assigned identification numbers, and online account credentials. ACSA completed its investigation and identified the impacted individuals in early May 2024.
