Want to transfer a file between two computers, but both are behind layers of bastion hosts?

This CTFd instance has a bunch of security CTF challenges written by kuilin. All of them are hard, some exceptionally hard.
All of these are solvable with only info from CTFd, but here's the repo these are deployed from: https://github.com/likuilin/ctf-challenges
Of course, the write-ups contain solutions. The flags were updated for this deployment, though (at least, the ones where they're changeable).
