Yacht retailer MarineMax discloses data breach after cyberattack

MarineMax disclosed that a cybercrime group accessed a portion of its retail environment in March and exfiltrated limited customer and employee personally identifiable information; the Rhysida ransomware gang has claimed the attack and is advertising the stolen data for sale on its leak site for 15 BTC, posting screenshots of financial documents and IDs. The report contextualizes Rhysida as a RaaS operation with prior breaches (British Library, Chilean Army, Insomniac Games) and notes warnings/advisories linking the group to opportunistic attacks across sectors.
