Hertz Data Breach Exposes Sensitive Information: What You Need to Know

What do a car rental giant and a file transfer platform hack have in common? This week, thousands of businesses—and their customers—just found out. When Hertz, the household name in rental cars, revealed a data breach tied to the Cleo file transfer system hack, it sent shockwaves through both the automotive and cybersecurity industries. But what really happened, who’s at risk, and—most importantly—how can you safeguard your information?

Hertz Data Breach: The Cleo Hack Connection Explained

This wasn’t your run-of-the-mill phishing scam. Instead, the attack originated from a vulnerability in Cleo Integration Cloud, a widely used managed file transfer (MFT) platform. According to SecurityWeek, Hertz confirmed that unauthorized actors exploited this flaw, gaining access to sensitive files transferred through the system.

The Cleo hack rippled across multiple industries, but Hertz stood out due to the scope of potentially exposed data, ranging from rental agreements to customer contact details. As more details emerge, the Hertz breach is becoming a textbook lesson on the interconnected risks of vendor technology.

What Data Was Compromised in the Hertz Breach?

While Hertz and Cleo are still assessing the full impact, preliminary reports indicate that the breach may have exposed:

• Customer names and contact information
• Driver’s license and ID numbers
• Payment card data (in some cases)
• Employee HR records
• Rental history and agreements

It’s a hefty list, underscoring just how much personal information travels through third-party platforms—often behind the scenes of everyday transactions.

Why Third-Party Risk Management Matters More Than Ever

Hertz’s incident isn’t isolated. More than 60% of breaches today, according to a 2023 report by the Ponemon Institute, involve third-party vendors or suppliers. The Cleo hack echoes this trend, proving that your security is only as strong as your partners’ defenses.

Lessons from the Hertz Data Breach

• Transparency is crucial: Hertz’s timely disclosure built trust, but not all companies act so quickly.
• Vendor cybersecurity assessments should be ongoing, not annual: Regular, real-time audits help pinpoint evolving risks.
• Data minimization reduces your exposure: Only collect and store what you truly need—both for customers and internal operations.

As cybersecurity expert Dr. Elaine Foster (paraphrased) emphasizes, “In the era of interconnected ecosystems, companies must demand—and verify—robust security posture from every technology partner.”

How to Protect Yourself After the Hertz Breach

For Hertz Customers and Employees

• Monitor bank and credit card statements for unauthorized activity
• Consider placing a temporary credit freeze with major bureaus
• Change passwords, especially if reused elsewhere
• Be wary of phishing schemes exploiting breach news

For Businesses Relying on MFT Platforms

• Conduct immediate vulnerability assessments of your own integrations
• Review vendor incident response procedures
• Update internal and customer communication plans for timely breach notifications
• Implement multi-factor authentication for all sensitive systems

Real-World Examples: Cleo Hack’s Industry Impact

Hertz wasn’t the only organization caught in the crossfire. Human resources software vendors, logistics providers, and even some financial services firms using the Cleo Integration Cloud have reported similar unauthorized access attempts. The Hertz breach stands as a warning: no matter your size or sector, digital supply chain security gaps can have real-world consequences.

Stay Proactive: Don’t Wait for the Next Cybersecurity Incident

This breach won’t be the last, but it’s a timely reminder for both companies and individuals to double down on security vigilance. Whether you’re renting a car or running a business, ask tough questions about where—and how—your data is handled.
