On March 26, 2023 Western Digital encountered a cyberattack that led to unauthorized access to company systems and data theft. As a precautionary measure, the company temporarily suspended some services, including My Cloud on April 2. The suspension lasted for ten days, during which users were unable to remotely access files stored on their WD NAS devices. After the security assessment was completed, My Cloud functionality was restored.[5][6]
