Boat dealer MarineMax said the data breach caused by a recent ransomware attack impacts over 123,000 individuals.

Boat dealer MarineMax is informing more than 123,000 individuals about a data breach resulting from a ransomware attack launched against the company earlier this year.

The incident came to light in March, when MarineMax, one of the world’s largest retailers of recreational boats and yachts, revealed in an SEC filing that it was targeted in a cyberattack that had caused some disruption. 

The Rhysida ransomware group took credit for the attack, auctioning data allegedly stolen from the company. 

Screenshots published at the time by the hackers suggested they had obtained financial documents and spreadsheets, among other types of files.
