Hertz Data Breach: A Deep Dive into the April 2025 Cybersecurity Incident

In April 2025, Hertz, a well-known car rental company, experienced a significant data breach. This incident exposed sensitive customer information, highlighting the importance of robust cybersecurity measures.

What Happened?

Between October and December 2024, hackers exploited vulnerabilities in Cleo Communications, a vendor used by Hertz. This allowed unauthorized access to Hertz's customer data. The breach was confirmed by Hertz in February 2025 and further analyzed in April 2025.

Data Compromised

The attackers accessed various types of personal information, including:

  • Full names
  • Contact details
  • Birth dates
  • Credit card information
  • Driver's license numbers
  • Social Security and passport numbers (in some cases)
  • Workers’ compensation data

Response and Mitigation

Hertz has reported the breach to law enforcement and regulatory bodies. Cleo Communications has addressed the vulnerabilities exploited during the attack. As of now, there is no evidence of identity misuse related to this incident.

Lessons Learned

This breach underscores several critical points:

  • Vendor Security: Companies must ensure that their third-party vendors maintain strong cybersecurity practices.
  • Regular Audits: Frequent security assessments can help identify and mitigate vulnerabilities before they are exploited.
  • Incident Response Plans: Having a well-defined response strategy is crucial for minimizing damage during a breach.

Understanding the Breach Mechanism

To simplify, imagine your personal data as items stored in a locked box (your account). The hackers found a hidden key (the vulnerability) to open this box without permission. Once inside, they could see and take your information.

JavaScript Visualization

Below is a basic JavaScript example to illustrate how a vulnerability might be exploited:


// Simulating a vulnerable function
function accessData(userInput) {
  // Vulnerable code: directly using user input
  eval(userInput);
}

// Attacker's input
let maliciousInput = "console.log('Sensitive data accessed!')";

// Exploiting the vulnerability
accessData(maliciousInput);

Note: The above code is for educational purposes only. Using eval() with untrusted input is dangerous and should be avoided.

Conclusion

The Hertz data breach serves as a reminder of the ever-present cybersecurity threats in our digital age. Organizations must prioritize security at all levels to protect sensitive information and maintain customer trust.

Exploiting Path Traversal Vulnerabilities: A Step-by-Step Guide Exploiting Path Traversal Vulnerabilities: A Step-by-Step Guide Introduction Path traversal is a common web vulnerability that allows attackers to access files outside the intended directory. In this guide, we'll explore how to exploit and prevent this vulnerability using a real-world example. The Challenge The challenge involves a Flask-based web server that serves files from the /challenge/files directory. The server is vulnerable to path traversal due to improper handling of user input in the URL path. Server Code #!/opt/pwn.college/python import flask import os app = flask.Flask(__name__) @app.route("/files", methods=["GET"]) @app.route("/files/ ", methods=["GET"]) def challenge(path="index.html"): requested_path = app.root_path + "/files/" + path ...
