Challenge description

There’s something fishy about that list of board members… something’s hiding there… I just know it.

---

Approach

There is a Board Members page at /board.

In most browsers we can right click on the page and use ‘View Page Source’ to bring up the raw HTML of the page.

Doing so reveals some interesting comments.

<!-- RISC{ -->
<!-- l00k_m -->
<!-- 0m_1m -->
<!-- _a_r3 -->
<!-- 4l_1 -->
<!-- 337 -->
<!-- _h4ck -->
<!-- 3r_n0 -->
<!-- w!} -->

If we concatenate them we get the flag.

Or we can automate it in bash: curl "http://leftmanbrothers.ctf.urisc.club/board" &>/dev/null | sed -n "s/.*<\!-- \(.*\) -->/\1/p" | tr -d "\n"; echo

RISC{l00k_m0m_1m_a_r34l_1337_h4ck3r_n0w!}
