Healthcare extortion claims threaten large patient-data exposures

ShinyHunters claims access to as many as 284 million McKesson records following alleged help-desk social engineering and MFA-reset activity; McKesson is investigating and the claim remains unverified. A separate AWS-related healthcare breach may affect approximately 3.75 million patients and exposed Social Security, medical, identity, and financial information. Additional small healthcare vendor and email-breach reports reinforce exposure risks but add limited technical detail.
