soal

Kishor Balan tipped us off that the following code may need inspection: https://jupiter.challenges.picoctf.org/problem/9670/ (link) or http://jupiter.challenges.picoctf.org:9670

hint

  • How do you inspect web code on a browser?
  • There’s 3 parts

solve

  • disini jika kita lihat dia membuat web ini dengan html, css, js alt text
  • mungkin saja flagnya terdapat di 3 file itu
    • view-source:https://jupiter.challenges.picoctf.org/problem/9670/index.html <!-- Html is neat. Anyways have 1/3 of the flag: picoCTF{tru3_d3 -->
    • https://jupiter.challenges.picoctf.org/problem/9670/mycss.css /* You need CSS to make pretty pages. Here's part 2/3 of the flag: t3ct1ve_0r_ju5t */
    • https://jupiter.challenges.picoctf.org/problem/9670/myjs.js /* Javascript sure is neat. Anyways part 3/3 of the flag: _lucky?2e7b23e3} */
  • lalu gabungkan flagnya sesuai urutan picoCTF{tru3_d3t3ct1ve_0r_ju5t_lucky?2e7b23e3}

flag

picoCTF{tru3_d3t3ct1ve_0r_ju5t_lucky?2e7b23e3}
