Cencora, Inc.

Cencora distributes drugs, but through its Lash Group patient-support arm it had become the record-keeper for more than a dozen rival drugmakers, so one February intrusion emptied the patient files of Bayer, Novartis, and Bristol Myers Squibb at once. Names, diagnoses, and medications for at least 1.43 million people left through a single back-office unit no one filed as a front door. Reporting ties the theft to Dark Angels and puts the ransom near $75 million, the largest known, which only buys a promise the copy was deleted.
