Hello world! Today, I am officially released, and you can use me to create and fuzz high-quality binary inputs at amazing speed - with optional coverage guidance, and without needing seed inputs. Read about me and download me at https://t.co/XhxiOlnmPJ

GIF Fuzzing! Here's me happily producing millions of GIFs – either from scratch, or coverage-guided with our AFL++ integration. Just do "make gif-fuzzer”, and detect incompatibilities between GIF libraries. (Or is it "jif-fuzzer"?) https://t.co/Nhkngg2wiM

Actually, I can produce and mutate MP3 and MIDI files :-)

Being fair to the Bot it did take me a second to fully register the degree to which this tweet is *not* about Music Production.

Next up: @_rahulgopinath and Rafael Dutra from @CISPA will demonstrate how fuzzers can be enhanced with an input language specification, in order to enable focused fuzzing and reach deeper parts of the code.
