40 SlotEyes Very difficult
88 wiretapscars pwn it up
88 Y311J Awesome!
80 nsr Overall pretty awesome quality, progressive ideas, only a couple of questionable challenges (such as puzzle_redacted, return_to_shellql.
88 saru difficult problems even it is speedrun.
44 theKidOfArcrania meh.... pwns were ok, but speedruns were frustrating as they disproportionately benefited large teams
88 vladvis great challs, but there were several issues: return_to_shellql and bad tagging (e.g. wasm reverse had pwn tag)
87 bookgin return_to_shellql is totally screwed up.......
44 felli0t pwn all day long
88 nosurf Difficult, liked the concept of speedruns though not enough variation
88 @MrTaharAmine !!!
88 Aqcurate Nice pwn challenges.
88 r3dey3 Considering this is specifically a qualifier for an attack/defense ctf, the amount of pwn is awesome
88 unlimitedx45 hardcore but I think that the challenges could be better classified in terms of categories
30 Ariana1729 web was just sad, crypto was quite a lot of reversing and bruteforce, kinda sad. Speedrun kinda would have benefited bigger teams imo, more
88 fpasswd Very cool challenges. It'd be nice if there were more challenges other than RE and pwn.
88 gnx Great CTF!
85 MrSpecterist Challenging...
88 mr_goron great
52 ret2got Not bad
50 ScepticCtf Liked the pwning challenges that I was involved in except for some basic mistakes like removing old download on challenge update
75 t1016d Nice, but could be better if there's more non-binary tasks.
47 niklasb Pwns & crypto that I looked at were interesting except 1. Could use more math+testing & less brute force. Heard some horror stories from tea
50 niklasb Pwns & crypto that I looked at were interesting with 1 exception. Could use more math+testing & less brute force. Heard some horror stories
88 Fish Great challenges, but the early ones were too hard :< Also, please stop labeling random challenges as "reversing".
25 maro Lack of variety, not bad overall
70 vient biased towards binary stuff but the quality of those is astonishing
88 gkrishna Good
83 Boschko pwn pwn pwn pwn
30 NicolaiS Too many pwn challenges. Only a single crypto and web challenge.
42 Staubfinger For the future please forget about "Web" and just make more pwn and rev - because the former is clearly not OOO's forte. Just leave it out.
88 nmbr_7 Good
88 poiko Very interesting and challenging tasks.
88 alfink Some issues (shellql, ooops-captcha); very hard; liked the speedrun idea, but 5 points is not rewarding enough
88 Mem2019 very challenging
20 thshadow It was challenging this year.
1 xtrm0 .
25 0xZ3V5 Very interesting and hard
25 poiko Very interesting and challenging tasks.
25 zajtarn 95% pwn/reversing. Would be fun to see more of other categories
1 terjanq Should be renamed to PWN CTF. Almost no other challs than pwn... Even other categories required either RE or PWN. Tasks changed during ctf.
