Western Digital Corp. today provided an update on a network security incident involving the Company’s systems.
On March 26, 2023, we identified a network security incident where an unauthorized third party gained access to a number of the Company’s systems.
On April 2, 2023, we disclosed that upon discovery of this incident, we implemented incident response efforts and initiated an investigation with the assistance of leading security industry experts. This investigation is underway and includes analysis to understand the nature and scope of data obtained by the unauthorized party.
As a precautionary measure to secure our business operations, the Company proactively disconnected our systems and services from the public Internet. We are progressing through our restoration process and the majority of our impacted systems and services are now operational. Our factories are and have been operational throughout this incident and we are shipping products to meet our customers’ needs. While initially impacted by our proactive measures, as of April 13, 2023, My Cloud service was restored. Account access to Western Digital’s online store also was impacted and is expected to be restored the week of May 15, 2023.
In collaboration with outside forensic experts, we confirmed that an unauthorized party obtained a copy of a Western Digital database used for our online store that contained some personal information of our online store customers. This information included customer names, billing and shipping addresses, email addresses and telephone numbers. In addition, the database contained, in encrypted format, hashed and salted passwords and partial credit card numbers. We will communicate directly with impacted customers.
We are aware that other alleged Western Digital information has been made public. We are investigating the validity of this data and will continue reporting our findings as appropriate.
