Hi, I'm looking for new members into xtal team, PM in Discord 0x3c3e#3013.
Looking for a team, im new to ctf's, but interested in pushing myself to learn and help the team.
You can send invitation to team T0k
Overall a great CTF with a lot of great challenges!
Good things:
- "ICan'tBelieveIt'sNotCrypto" was the most beautiful math riddle I saw in a few years!
- "Parking" challenge was great (a digital circuit made of a car parking puzzle).
- "Weather" RE was also really nice (VM implemented on glibc's printf custom format specifiers).
- Other challs were also quite good.
- I really liked the scoreboard :)
Bad things:
- "David and the Tree": This was a challenge which IMO should have never appeared on a top tier CTF. It was basically stego+guessing, where your only hope was that you guessed all the vague hints from the chall name and description the same way as the author expected, otherwise you wasted a few hours doing stego analyses on a wrong thing...
- "ABC ARM AND AMD": "We have made an update to the server of ABC ARM AND AMD to make it behave more closely to local execution. If your exploit previously failed on the server, consider trying again." - would be better if you just included the full setup for the challenge (e.g. the exact qemu commandline wasn't known).
