these days, when using the right vis techniques you can easily train something like resnet to find malware. some is even plainly obvious to the eye. some packers and encryption is easy to spot but more subtle patterns a neural network can identify. for a reverse engineer or malware analist, seeing what part of files contain 'executable code' is also possible. for example if shellcode is embedded in a different file type or such. check the chris domas video linked on the github. its pretty epic :D
