About CAZ Investments LP
CAZ Investments LP is a Houston-based registered investment adviser and multi-family office firm founded in 2001 by Christopher Zook. The firm manages approximately $10.8 billion in assets under management and serves institutional clients, family offices, and high-net-worth individuals across strategies including private equity, private credit, real estate, hedge funds, infrastructure, and alternative investments. Because the firm holds detailed financial, identifying, and personal records for its clients, a breach of its systems carries significant identity theft and financial fraud risk for those affected.
What Happened?
CAZ Investments LP was listed in a Texas Attorney General data security breach report (record BR-0005372), published on September 29th, 2026. According to the filing, an unauthorized party accessed the company’s systems between August 8th, 2026 and August 12th, 2026. The breach was discovered on August 25th, 2026, and affected individuals were notified by U.S. Mail. A total of 13,817 individuals were affected. The information involved includes names, addresses, Social Security numbers, driver’s license numbers, government-issued ID numbers (such as passports and state ID cards), financial account information (including account numbers and credit or debit card numbers), and dates of birth — a combination that creates serious risk of identity theft and financial fraud.
Separately, multiple threat intelligence platforms tracked a dark web leak-site posting by a ransomware group called “TheGentlemen,” dated August 21st, 2026, in which the group claimed responsibility for an attack on CAZ Investments and alleged it had exfiltrated over 478 GB of data. These are unverified attacker claims and have not been confirmed by CAZ Investments or any regulator. Notably, the group’s public posting (August 21st, 2026) preceded the company’s stated discovery date (August 25th, 2026) by four days. CAZ Investments has not publicly confirmed whether the incident was ransomware-related. No prior data breaches specific to CAZ Investments were identified, and no class action litigation connected to this breach had been filed as of September 29th, 2026.

What Should You Do?
If you received a notice from CAZ Investments LP, act promptly to protect yourself. Place a fraud alert or credit freeze with each of the three major credit bureaus — Equifax, Experian, and TransUnion — to make it harder for someone to open new accounts in your name. A credit freeze is free and can be lifted at any time. Review your credit reports for unfamiliar accounts or inquiries by visiting AnnualCreditReport.com. Monitor your existing bank and credit card accounts closely for unauthorized transactions. Because Social Security numbers, government-issued IDs, and financial account information were all confirmed to be involved, the risk of identity theft is elevated; report any suspected misuse to the Federal Trade Commission at IdentityTheft.gov, which can generate a personalized recovery plan.
