If you're into CTFs or just want to try something new, come join. Feel free to share it with your friends too, would love to see more people join in.

Came across this one while browsing CTFtime and thought it was worth sharing here since the challenge list looks different from the usual.

There's also OSINT, recon, and some bonus stuff.

Prizes are $750 / $500 / $250.

19 days to go.

I’m looking for someone to help me with a challenge. I’m stuck and don’t know what else to try. It’s an OSINT challenge focused on obtaining the flag from a series of sound and visual information vectors. All the files needed to decrypt the flag are in the ZIP. There are many decoy flags—I found more than 10 false flags. I would really appreciate any support so I can resolve this and learn more. The CTF isn't active anymore, but I want to solve it.

Here is what I have tried so far:

• LSB steganography on the 16 cover images (zsteg, all bit/channel/order combinations)
• Hidden file signatures (binwalk on all 34 files)
• ID3 tags on the 16 audio tracks (Base64)
• Metadata across all files (exiftool)
• MAYANMAP as a numerical cipher (values, rule positions, order)
• Vector layer analysis of both PDFs (rectangles/lines/curves)
• Font glyph remapping

Any help is appreciated. Thanks!
