solve

  • jadi saya mencoba mengganti user agent punya saya dengan extension alt text
  • atau gunakan curl
    curl https://jupiter.challenges.picoctf.org/problem/50522/flag -H "User-Agent: picobrowser" | grep pico
    
    # <div class="jumbotron">

    #     <p style="text-align:center; font-size:30px;"><b>Flag</b>: <code>picoCTF{p1c0_s3cr3t_ag3nt_51414fa7}</code></p>
    #     <!-- <p><a class="btn btn-lg btn-success" href="admin" role="button">Click here for the flag!</a> -->
