Yacht dealer to the stars attacked by Rhysida ransomware gang

Rhysida ransomware claims responsibility for an attack on MarineMax, posting snippets of purportedly stolen accounting/financial documents and offering the data in a seven-day auction with a current asking price of 15 BTC (~$1.007M). MarineMax filed an SEC Form 8-K noting operational containment; Rhysida’s tactics align with prior activity described in a CISA advisory (phishing, stolen credentials, and exploitation such as Zerologon), and the group has previously targeted other high-profile organizations.
