A significant data breach has impacted McKesson, a major U.S. pharmaceutical distributor, with hackers claiming to have stolen millions of sensitive patient records. The cyberattack, attributed to the prolific hacking group ShinyHunters, represents the latest in a series of escalating threats against the healthcare sector.

Mckesson confirmed the breach occurred earlier this week, affecting several cloud-hosted accounts. The company has alerted customers that the incident may lead to intermittent service disruptions. According to internal communications, the compromised data specifically pertains to McKesson’s oncology & multispecialty and medical-surgical divisions.
