MCKESSON , a major healthcare and pharmaceutical distribution company, has reported a cybersecurity incident involving unauthorized access to third-party applications and a data breach. The ShinyHunters extortion group claims to have stolen 284 million patient records. McKesson filed a disclosure with the SEC and stated they are investigating the breach but do not currently believe any action is needed from customers.
The statement does not mention specific applications involved or confirm the claims made by ShinyHunters, who has a history of exaggerating breach claims. The incident was first reported by CyberInsider.
