Mercer Advisors, Beacon Pointe Advisors and Pathstone Family Office: Pathstone Family Office allegedly breached by ShinyHunters

ShinyHunters Claims Breach of Elite Wealth Firm Pathstone Family Office

Cyber extortion group ShinyHunters has alleged a breach of Pathstone Family Office, a wealth management firm serving high-net-worth clients. In a post on its dark web leak site, the group claimed to have exfiltrated 641,000 records, including personally identifiable information (PII) and internal corporate documents. Pathstone was given until March 2 to respond before the data was reportedly set to be released.

Pathstone, which manages $170 billion in assets for over 750 families, has not confirmed the breach, and no sample data has been provided to verify the claim. If substantiated, the exposed records could include legal paperwork, estate planning details, financial structures, and client contracts, posing risks of fraud, impersonation, intellectual property theft, and reputational harm.

ShinyHunters has recently targeted other financial advisory firms, including Beacon Pointe Advisors and Mercer Advisors, later publishing alleged stolen data. The group has also been linked to past breaches involving Waltio, Salesforce CRM, Crunchbase, and Bumble.
