Private equity firm Apollo Global Management has notified individuals that hackers accessed sensitive personal information, including Social Security numbers, following a social engineering incident in early July.

Key Points

• Unauthorized access to Apollo cloud platforms occurred between July 6 and July 10, 2026.
• Stolen data includes names, dates of birth, contact details, home addresses, and Social Security numbers.
• Apollo is offering affected individuals 24 months of credit monitoring services through Cyberscout, a TransUnion company.
• The breach impacts residents in seven jurisdictions, including California, New York, and the District of Columbia.
• No specific threat actor has claimed responsibility, and Apollo reports no evidence of the stolen data being misused for fraud yet.

Why it Matters

This incident highlights the growing vulnerability of major financial institutions to sophisticated social engineering attacks that bypass traditional security protocols. As firms like Apollo manage nearly $1 trillion in assets, such breaches underscore the significant risks posed to the personal data of employees and investors alike.
