McKesson copes with fallout from data theft extortion attack
McKesson discloses a data theft extortion attack by ShinyHunters affecting oncology and medical-surgical customers, with a reported $55 million demand.
McKesson disclosed that attackers gained access to some of its third-party applications and stole data associated with a subset of customers in its oncology, multispecialty, and medical-surgical business units; the intrusion ran for four days from August 21 and was discovered August 25. ShinyHunters claimed responsibility and listed McKesson on its data-leak site, reportedly demanding more than $55 million with a September 1 deadline. Flashpoint analysts say the group typically uses social engineering and identity weaknesses with valid credentials to access cloud-hosted environments, making the intrusion hard to detect. McKesson, which distributes about one-third of pharmaceuticals used in North America with $403.4 billion in annual revenue, says operations continue and it has reasonable assurance of no ongoing unauthorized activity.
