On February 15, 2021, Hawaii Payroll Services LLC experienced a ransomware attack that began when an unauthorized actor gained access through a compromised client account. The attacker escalated privileges, disabled security software, and encrypted server data, leading to a disruption of services. Approximately 4,500 customers had their personal information exposed, including Social Security numbers, bank account details, and other personal data. In response, the company suspended remote client access, engaged third‑party IT support, and retained forensic experts to investigate and remediate the incident. Although some encrypted data was recovered, full file access remained unresolved, notifications were sent to affected individuals (with some delivery issues), and law‑enforcement investigations were initiated, though no arrests or evidence of dark‑web misuse were reported at the time.
