ZOLL Medical has notified its customers of a data breach affecting customer data in late January. The company confirmed that an unauthorized third party may have obtained access to some individuals’ protected health information (PHI). 

The PHI may have included some individuals’ names, addresses, dates of birth, some Social Security numbers and information that may allow one to infer that the individual used or was considered for use of their wearable cardioverter defibrillator (WCD).
