For christmas this year I give you 20 hand crafted payloads for the flipper and I just updated all of them.
85% of these are plug and play so you don't even have to host your own copy, just modify a single variable in the one liner to run it. 1000 hours of work, enjoy!

You can use my website to generate a polymorphic reverse shell and store it in a DNS txt record
Instead of just using resolve-dns to pull it down and execute it lets abuse google's DoH service so they not only fetch it for us but the traffic is encrypted and proxied

Key advantages:
Evasion: Skirts security tool detection by avoiding commonly flagged tools like PowerShell.
