AFL algorithm

[21212124]

I would like to know where is the part of the afl algorithm where the seeds change. Where is it implemented? Does it change randomly?

TLDR; There are numerous fuzzing strategies being used (bit/byte flips, splicing and more).
You can find out how inputs are mutated at chapter 6) Fuzzing strategies from https://github.com/google/AFL/blob/master/docs/technical_details.txt

As to where it's implemented, check afl-fuzz.c (Prepare yourself, it's overwhelming)

En cuanto a dónde se implementa, verifique afl-fuzz.c (Prepárese, es abrumador)
https://github.com/google/AFL/blob/master/afl-fuzz.c

You don't know where it is implemented? It is hard to find?

Looks like it is somewhere here: https://github.com/google/AFL/blob/master/afl-fuzz.c#L6128
