If you have any of these, I can help you with any challenge other than these.

solved rsa and babygame3 help me with format string 3

I tried to contact you too. Maybe I am not familiar with the platform. Could you receive my message?

Here's a solver script for endianness-v2. I've not been on this forum long, but I find the whole trading thing to be stupid. I would rather just share hints or writeups.

So knock yourself out, run it from the directory you have your "challengefile", it creates an image called "reordered_file" in cwd, open it and read your flag.

def reorder_bytes(file_path):
    with open(file_path, 'rb') as original_file:
        original_bytes = original_file.read()
   
    reordered_bytes = b''.join(original_bytes[i:i+4][::-1] for i in range(0, len(original_bytes), 4))

    with open('reordered_file', 'wb') as new_file:
        new_file.write(reordered_bytes)

reorder_bytes('challengefile')

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.

how about elements do you have some hint ?

[Gasmo12706]

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 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.
