Tentang Saya

Halo, nama saya Raffael Putra Hermawan, tetapi Anda bisa memanggil saya El atau Rafa. Saya berusia 15 tahun dan telah memiliki pengalaman selama 4 tahun di dunia siber dengan fokus utama pada keamanan siber, peretasan etis, serta uji penetrasi. Saat ini, saya adalah siswa kelas 10 di SMAN 14 Depok.

Saya telah memperoleh lebih dari 26 sertifikasi dan berpartisipasi dalam berbagai kompetisi siber yang diselenggarakan oleh perusahaan besar serta lembaga pemerintah, baik di tingkat nasional maupun internasional. Saya dapat menulis kode menggunakan HTML, CSS, JavaScript, Python, Bash, dan bahasa pemrograman lainnya.

Selama perjalanan saya, saya telah mengerjakan berbagai proyek — baik yang berhasil maupun gagal. Saat ini, saya sedang mengembangkan sebuah proyek bernama ovtb project, yang bertujuan untuk menciptakan sistem keamanan adaptif dan efisien di dunia digital modern.

Big Project — ovtb project

ovtb project

ovtb project merupakan bot Telegram berbasis Python yang dikembangkan sendiri (tanpa tim). Bot ini dirancang untuk keperluan OSINT, pentesting, dan analisis digital lain pada ranah yang diperbolehkan.

Fitur utama meliputi:

  • OSINT: mencari data berdasarkan satu informasi (mis. nama) dan mencocokkan ke database untuk menemukan jejak terkait.
  • FileInt: menganalisis file untuk melacak metadata atau jejak—misalnya mendeteksi indikasi lokasi pada foto sehingga user dapat menelusuri informasi lebih lanjut terkait foto tersebut.
  • IQC: pembuatan iPhone quote chat (format quote khusus untuk keperluan presentasi atau dokumentasi).
  • QRGen: pembuatan QR yang berisi pesan atau mengarah ke URL; QR dapat dimodifikasi (warna, background transparan).
  • Kodepos Checker: mencari lokasi berdasarkan kodepos di database berisi informasi kode pos di seluruh negara.
  • PhoneInt: pencarian ISP dan lokasi kasar; menggunakan database ISP global untuk akurasi yang lebih baik.
  • URL Checker: analisis mendalam sebuah URL untuk mencari informasi seperti IP asli, versi, atau indikator teknis lain secara deep.
  • AutBugHunt: modul yang men-scan potensi celah menggunakan curl secara otomatis, full automasi — user hanya perlu memasukkan URL.

Masih banyak lagi fitur-fitur lainya, namun masih tahap pengembangan — penggunaan gratis 1 minggu. Laporkan bug atau request fitur yang tidak biasa untuk membantu keamanan siber.
