On February 12, 2022, Cytometry Specialists, Inc., doing business as CSI Laboratories (“CSI”), became aware of a cyberattack that partially disrupted CSI information systems.
Upon learning of the incident, CSI immediately took steps to isolate and secure its systems and to investigate the incident. As part of the investigation, on February 25, 2022, CSI determined that an unauthorized intruder acquired certain files from CSI systems, including documents that may have contained patient information. Since then, we have been analyzing affected files to understand what information may be at risk, identify affected individuals, and obtain contact information; we are also working to notify people and authorities, as appropriate.

Some of the affected files contained very limited patient information, such as the case number, which is a unique identifier used in place of the patient’s name to identify a sample. Some affected files contained more information, including the patient’s name, date of birth, address, medical record number, and health insurance information. None of the files contained a social security number or financial account information. At this time, CSI has no facts to suggest that any of the information has been used further, and in some cases it will be very difficult, if not impossible, for anyone to continue to use the information that was accessed.
CSI hired a well-known forensic investigation firm to identify the scope of the incident and help protect its systems and data. CSI has carefully brought its systems back online and continues to closely monitor its network and information systems for unusual activity. CSI will continue to further enhance the security of your company’s networks and protect against unauthorized access or similar criminal activity in the future.
