Some screenshots of the stolen data has been released on the REvil site on the dark web, with the attackers claiming they have data on tax, logistics, and personal data on clients and employees.
Matson, which was founded in 1882, has annual revenue of about US$2 billion.
It has a subsidiary, Matson Navigation Company, that provides ocean shipping services across the Pacific to Hawaii, Alaska, Guam, Micronesia, the South Pacific, China and Japan, according to Wikipedia.
The attackers warned that they would put up the stolen data for auction, and would release about 3GB of the data on dark web for prospective buyers to review.
REvil, which is also known as Sodinokibi, has been used in many attacks this year. It was used to hit the big casino equipment suppllier Gaming Partners International Corporation, the Meinhardt Group, an engineering consultancy with 51 offices worldwide and 5000 employees, American IT staffing company Artech Information Systems, and publicly traded professional distribution management firm DXP Enterprises.
Others to suffer were Adif, an infrastructure company owned by the Spanish Government, Argentina's biggest Internet service provider Telecom Argentina, leading retirement specialist Actuaries and Associates, the website of Cooke County in Texas, and Australian drinks manufacturer Lion.
Melbourne-based contract formulation and packing company Chem Pack, New York-based entertainment and media lawyers Grubman Shire Meiselas & Sacks, Sydney sports specialty store chain Instore, American food distribution firm Harvest/Sherwood Food Distributors, SeaChange, a global public supplier of video delivery software, and Melbourne-based government-accredited IT services provider Geidi were all hit by gangs using REvil as well.
