Let’s talk about... 
(analogies between animals & file formats)
Identification
By its head ?
By shape ?
By sound ?
metadata 
aka who’s the owner?
A hidden cow just looks like another cow...
… so cattle is branded.
But brandings can be faked! 
or “patched” into another symbol
… and in a pure PoC||GTFO fashion, 
Munin forged a branding iron !
Parsing
This is a how a user sees a cow.
This is how an expert sees a cow...
This is how another expert sees a cow !
Same data, different parsers 
it would have been too easy ;)
Standard properties
Cow can be seen in chunks.
It’s a complete cow (you can see its whole body), with something next. 
A cow with appended data is still valid cow.
If our cow swallows a microSD, it’s still a valid cow! 
Even if it contains foreign data, that is tolerated by the system.
Extremes bypass rules 
(this example is actually a hoax) 
se non è vero, è ben trovato
A farmer was denied permit to build a horse shelter, 
so he builds giant table & chairs which don’t need a permit.
Polyglots 
1 file, 2+ types
the town musicians of Bremen 
(a donkey, a dog, a cat, a rooster)
If our cow keeps a frog in its mouth, it can also speak 2 languages!
Chimera 
count head, or bodies ?
Cerbero 
same type of heads
