Morgan Stanley notified the California AG of a data security incident involving a third-party vendor (Shareworks) that provides account maintenance services for Morgan Stanley's Stock Plan business. In May 2021, the vendor informed Morgan Stanley that an unauthorized individual had obtained personal information, including names, addresses, dates of birth, and Social Security numbers, from files in the vendor's possession. The data was obtained around January 2021 when the vendor's vulnerability was remediated. Morgan Stanley offered 24 months of complimentary credit monitoring through Experian to affected individuals.
