As it was the only service that (almost?) no teams exploited a solution for it would be especially interesting.

@semchapeu I guess you saw SIGFLAG write-up and the twitter thread already?

@nescio007 Well the SIGFLAG write-up is not a solution, just luck :) But thank you for linking the twitter thread. Guess it might not be solvable at all, just sucks as I and others spent the whole CTF on it.
