Punycode attacks exploit visually similar Unicode characters in domain names, allowing attackers to create look-alike domains that bypass security controls. When applications fail to properly validate or normalize internationalized domain names (IDNs), this can result in authentication bypass, password reset abuse, and full account takeover. This video explains the attack clearly, shows a real Proof of Concept (PoC), and discusses how such vulnerabilities should be fixed. 🔍 What’s Covered in This Video ✔ What is Punycode & IDN Homograph Attacks ✔ How Unicode domains bypass validation ✔ Real-world Account Takeover attack flow ✔ Critical P1 bug PoC demonstration ✔ Security impact & risk analysis ✔ Proper remediation & defense techniques ⚠️ Security Impact (Why This Is P1) If exploited, this vulnerability can allow attackers to: Take over user accounts Bypass email or domain-based validation Abuse password reset flows Perform phishing with trusted-looking domains Compromise sensitive user data Because it directly leads to Account Takeover, this issue is considered Critical (P1). 🛡️ Recommended Mitigation ✔ Normalize and validate Unicode domains ✔ Enforce ASCII-only domains where possible ✔ Convert and compare domains using Punycode consistently ✔ Detect and block homograph characters ✔ Add user-facing domain warnings 📚 Educational Disclaimer This video is created strictly for educational and security awareness purposes.
