Index Fund Advisors has begun sending out data breach notification letters to individuals impacted by the security incident. The company has stated that there is not yet any evidence of data misuse, though personal data is already at risk.

In August of 2021, Index Fund Advisors detected possible unauthorized access on their network and began investigating with a third-party cyber forensics firm. After a data breach review, Index Fund Advisors determined personal information was contained, and thereby compromised in the attack. The personal information in the hacked email accounts may include the following:

  • Names
  • Addresses
  • Dates of birth
  • Financial information
  • Social Security numbers

The Lyon Firm encourages all potentially affected individuals to act quickly and remain vigilant against potential identity theft and fraud by reviewing account statements and credit reports. Contact a privacy attorney to review your case.
