Apollo Global Management Data Breach

Apollo Global Management, a New York-based alternative asset manager overseeing hundreds of billions of dollars in assets, has notified individuals that a cybersecurity incident may have compromised their personal information. Financial firms that manage this kind of data are entrusted with protecting it from unauthorized access, and when that trust is broken, the people whose information was exposed deserve clear answers and a path toward protection.

Apollo Global Management’s Data Breach Investigation

According to a notice sent to affected individuals, Apollo experienced what it describes as a “social engineering incident” affecting the security of personal information in its systems. Upon detecting the incident, Apollo says it promptly notified law enforcement, engaged outside cybersecurity and forensic experts, enhanced its security protocols, and launched a formal investigation into what happened.

Apollo’s investigation determined that an unauthorized party gained access to certain of the firm’s cloud platforms between July 6 and July 10, 2026. The firm says it learned on August 12, 2026 that the information potentially affected by this access included individuals’ names, dates of birth, contact information, home addresses, and Social Security numbers.

This incident follows a broader wave of social engineering attacks reported in August 2026 that targeted major U.S. private equity and financial services firms. According to reporting from Reuters, hackers used “meticulous social engineering tactics,” calling employees directly on their personal cellphones while posing as internal IT help desk staff, in some cases even displaying a spoofed version of the company’s real help desk phone number, in an effort to trick employees into resetting passwords or multifactor authentication credentials. Apollo was reportedly among the firms targeted in this broader campaign.

Apollo states it has no evidence that the affected information has been publicly posted or misused for identity theft or fraud as of the date of its notice, though the investigation remains ongoing and additional updates may follow. Given the sensitivity of Social Security numbers and other identifying information involved, affected individuals face a real and ongoing risk of identity theft and financial fraud, and a firm that stores this kind of data has an obligation to protect it with reasonable safeguards.

When Did This Breach Occur?

Apollo’s investigation determined that unauthorized access to its cloud platforms occurred between July 6 and July 10, 2026. The firm says it learned on August 12, 2026 that personal information had been potentially impacted, and began sending written notification letters to affected individuals dated August 21, 2026.

What Information Was Breached?

Apollo’s notice states that the following categories of information were potentially affected: full name, date of birth, contact information, home address, and Social Security number. The involvement of Social Security numbers alongside other identifying details significantly heightens the risk of identity theft for those affected.
