I would like to know if there's any hint for flag printer. It is such a large parameter. I cannot think of any fast solution. I wonder if I am required to know any special mathematical concept. I only know the process is trying to do polynomial interpolation but I cannot solve it fast.

Could someone help me in those? C3, format string 2 & 3, heap 3 and WinAntiDbg0x300?

Anyone have a tiny hint for "Dear Diary"? I feel like I'm very close, but I don't know if I'm in a rabbit hole, or close to the ending.

You can use autopsy for dear diary and use .txt in search

ive done dear diary , I can help provided if you could also help me, with sansalpha or endianness-v2

I can help you with endianness-v2 if you help me with "Dear Diary"

I agree with the poster above. I think the trading is stupid. Anyone wanna publicly give me a hint in RSA-Oracle? I don't know what I am doing wrong.

I can give a hint for SansAlpha. /???/????64 is base64, and prints the output in base64. But! The command is 1/3 that matches the /???/????64 search, so you have to select the first binary (in a variable).
The flag is located at */????.???

Feel free to ask more questions. I have completed all forensics and general skills.

I found where flag.txt is using ./*/* but how do I get the output from the file?

Use the base64 function as a print. But since the wildcards yield 3 different binaries, you have to select the first one, which is base64. To do this, store it in a list: _420 = (/???/????64). Then, select the first element: "${_420[0]}". Now you can run the base64 command. Run it on the file and you have the flag.

Thanks! You are the GOAT!

I've started working on the other categories now that general and forensics are done, will let you know if I find anything on rsa_oracle

Same over here,  tried to solve flag_printer for over a week now with no luck. PM me if you have any help

C3 is super easy and but has a very dumb ending... first, we know that ciphertext is encoded using convert.py so we need to reverse the convert.py script to get the unencrypted version
Save the result to part2.py and fix any syntax errors
Next we need to pass thru part2 into part2 by doing

cat part2.py | python part2.py

to get our flag (don't worry if it's really short)

what do you mean by the last part run it on the file and you have the flag?

Anyone can help with elements? I have rsa_oracle, Dear Diary, SansAlpha, and babygame03

Like this:

SansAlpha$ "${_420[0]}" */????.???

does anyone have a picoctf account that's registered for pico 2024 that i can use?
