WASHINGTON — The Steamship Authority of Massachusetts ferry service fell victim to a ransomware attack Wednesday, the latest cyber assault affecting logistics and services in the United States.

“The Woods Hole, Martha’s Vineyard and Nantucket Steamship Authority has been the target of a ransomware attack that is affecting operations as of Wednesday morning,” the company wrote in a statement, adding that customers may experience delays.
