Apollo confirms July 2026 cyberattack via social engineering exposed PII in its cloud environment

Data included names, DOB, contact info, addresses, and Social Security numbers

Firm offers two years of identity protection; no evidence of dark web leaks yet

Apollo, one of the biggest private equity firms in the world, has confirmed it suffered a cyberattack which compromised some people’s personally identifiable information.

The company notified California’s Attorney General’s Office about the breach and shared a copy of the letter it is now sending out to affected individuals. It is impossible to discern from the letter if the victims are Apollo employees, customers, or someone else entirely, but the company did clearly explain what happened.

As per the letter, an unidentified threat actor tricked an Apollo employee into granting them access to the company’s cloud environment. The attackers used social engineering (usually phishing), which means the victim either tried logging in using a spoofed landing page, unknowingly installed an infostealer, or was convinced to grant the attackers access via remote monitoring and management software.

Was there really a hack?

The company spotted the attack a few days later, and after activating its safety protocols (notifying the police, enhancing its security protocols, and bringing in third-party forensic experts), launched an investigation which showed that the attackers accessed its cloud platform between July 6 and 10.

“During our investigation, we learned on August 12, 2026 that the information potentially impacted by this incident included your name, date of birth, contact information, home address, and your Social Security Number (SSN),” the company said. This means that financial data such as credit card or bank account information, was not compromised.

Still, cybercriminals can make use of this type of information, as is often the case in identity theft , business email compromise, and even wire fraud.

Apollo is now offering two years of free identity theft protection and monitoring for affected individuals through Cyberscout.

At press time, no threat actors claimed responsibility for the attack, and the data has not yet surfaced anywhere on the dark web.
