From the Washington, California and Delaware Attorney General breach notification lists, as posted. A notice is the organization's own report under state breach-notification law; it is not a finding of wrongdoing or of harm. California does not publish cause or counts in its list; Delaware lists data types and counts but not cause. Read the notice on the AG site before relying on it.
