On January 9, 2026, Betterment LLC, a fintech robo-advisor, experienced a data breach stemming from social engineering against an employee. This led to unauthorized access to a third-party marketing and communication platform used for customer messages. Betterment published a customer update page on the same day.
The breach exposed names, email addresses, physical addresses, phone numbers, dates of birth, the last four digits of Social Security Numbers, and account balances as of January 9, 2026, for approximately 1.4 million customers and business contacts. No full Social Security Numbers, medical information, or financial information beyond account balances were compromised. Additionally, no customer investment accounts, passwords, or login credentials were breached.
Details can emerge later, and official notices may be delayed.
