    Pretty cool challenge, learned some new tricks. What I did wasn't reversing per se, but it should be possible.

    Nice challenge. I used a disassembler and some breakpoints to get the flag.. But i don't undestand how i could get the flag with static analysis. Someone could pm me?

    If someone finds a way to get the flag with static analysis PM me.
    I created the Challange and it was meant to use a Debuger like Dnspy :)

    Well I dont think so. If you read the challange description you can see that you must bypass something....

    It took me longer to clone and build dnSpy than to do the bypass 😁.
    Great tool!! Thanks

    First time using dnSPY. I had difficulties recompiling the code but found a work around. Overall cool simple challenge. PM for nudge

    Cool challenge, I first tried the other spy, but the obfuscation was "unbreakable" :-). Learned something new.

    I did in fact complete the challenge via static analysis. I'll PM you.

    This was fun. I didn't know much about .NET and reversing it, nor did I know much about the tools to do it, so this was a very nice way to get to know them both.
