Fred Hutchinson Cancer Center (Fred Hutch) disclosed a November 2023 cyberattack where criminals stole personal and sensitive data, including health insurance information, patients' treatments, diagnoses, and lab results. The attackers used this data to carry out aggressive extortion tactics, directly contacting patients and threatening them with swatting attacks. The FBI was involved, and the cancer center agreed to a $52.5 million settlement, which includes cash payments, infrastructure improvements, and medical fraud monitoring and insurance for affected individuals.
