About Me

Hello, my name is Muhammad Daffa. I lived in Sidoarjo, East Java. I am an undergraduate student from the Institute of Technology Sepuluh Nopember majoring in informatics engineering. I am interested in cybersecurity, especially in the field of web application penetration testing. And now trying to learn something new like mobile penetration testing and forensic. I enjoy meeting new people, having new experiences, and being able to work both individually and in groups.
