πŸ‘¨β€πŸ’» Β About Me

I am a passionate Offensive Security Engineer from afine, committed to finding πŸ‘Ύ bugs and developing πŸ€– software that enhances our work in security. My main areas of interest are 🍎 macOS internals and πŸ•ΈοΈ web application security. I also have experience in πŸ’  Active Directory and creating 🦠 malware to bypass πŸ›‘οΈ EDRs.


πŸ”­ Projects I am proud of

I created some tools helpful for Offensive Security work, but there are two that I am the most proud of, they are:

  • Crimson - this was my first big thing. Currently, I am not focusing on this tool. However, it is still powerful. My friends and I are using it to this day. This is also a great place to start your journey with Application Security.
  • Snake&Apple - The code repository for the Snake&Apple article series documents my macOS security research.
