Summary#

Hands-on experience with both offensive security techniques and defensive countermeasures. Understanding how attacks work at a low level enables building more secure systems. Emphasis on practical exploitation and mitigation strategies.

How I Apply This Skill#

• Executed buffer overflow attacks with shellcode injection and NOP sleds
• Exploited SQL injection vulnerabilities for authentication bypass
• Performed environment variable attacks via PATH manipulation for privilege escalation
• Implemented SYN flooding attacks to understand DoS mitigation
• Analyzed AES encryption modes (ECB vs CBC) identifying security implications
• Generated RSA key pairs using OpenSSL for secure communication
• Studied defensive countermeasures: ASLR, stack canaries, SYN cookies

Key Strengths#

• Memory Exploitation: Buffer overflows, stack smashing, shellcode execution
• Web Security: SQL injection, input validation, authentication bypass
• Network Attacks: SYN flooding, DoS patterns, TCP/IP vulnerabilities
• Cryptography: AES modes, RSA key generation, OpenSSL usage
• Defensive Security: Understanding countermeasures, secure coding practices
