Pharma giant Cencora this week confirmed that personally identifiable information (PII) and protected health information (PHI) was stolen in a February 2024 cyberattack.The incident was identified on February 21 and disclosed a few days later in a regulatory filing, when the company said that personal information was exfiltrated from its systems.In a July 31 filing with the Securities and Exchange Commission (SEC), Cencora said that “additional data, beyond what was initially identified, had been exfiltrated”.The company has identified and completed its review of most of the exfiltrated data. This review has confirmed that the data included personally identifiable information and protected health information of individuals, most of which is maintained by a company subsidiary that provides patient support services, Cencora said.Cencora also noted that the attack has not had a material impact on its operations, that its systems remained fully operational, and that no material impact on financial condition or results of operations is expected.The pharmaceutical giant, which believes it has contained the incident, said it has provided notifications to the impacted individuals and regulatory agencies, but did not share details on the stolen information.In May, however, Cencora subsidiary Lash Group announced that information stolen from its parent company includes names, dates of birth, health diagnosis, and/or medications and prescriptions.Lash Group said it was in the process of notifying the impacted individuals, but also posted an incident notice on its website, as it did not have address information to mail letters to all of them.Advertisement.

While Cencora is a Fortune 50 business, no ransomware group has claimed responsibility for targeting it.
