Security Disclosures

The Beginning

2014 marked my first real steps into computer science and cybersecurity. Through self-directed learning, I dove deep into understanding how mobile applications and websites actually work under the hood -not just from a user perspective, but from a technical security standpoint.

What I Discovered

By systematically analyzing security architectures and testing methodologies, I was able to identify and responsibly disclose critical security vulnerabilities in several high-profile companies:

• Domino’s Pizza - Identified vulnerabilities in their online ordering system
• Smart School - Found security issues in their educational platform (Read the coverage on PC.co.il)
• Yes Planet - Discovered vulnerabilities in their cinema booking system
• And several other companies across various industries

The Responsible Disclosure Process

Each vulnerability I discovered was carefully documented and disclosed through responsible channels. I worked directly with the affected companies to ensure vulnerabilities were patched before any public disclosure, prioritizing the security of their users above all else.

What I Learned

This experience taught me the fundamentals of:

• Security testing methodologies
• Responsible disclosure practices
• Mobile and web application security
• The importance of ethical hacking
• How to communicate technical findings to non-technical stakeholders

Looking back, this was the foundation that shaped my entire career trajectory. It showed me that security isn’t just about finding bugs -it’s about understanding systems, thinking like an attacker, and working collaboratively to make technology safer for everyone.
