Metame - Metame Is A Metamorphic Code Engine For Arbitrary Executables

[✨ DeeZNuTz]

Open a given binary and analyze the code
Randomly replace instructions with equivalences in logic and size
Copy and patch the original binary to generate a mutated variant
It currently supports the following architectures:

• x86 32 bits
• x86 64 bits

Also, it supports a variety of file formats, as radare2 is used for file parsing and code analysis.
Example of code before and after mutation:

Hint: Two instructions have been replaced in this snippet.
Here another example on how it can mutate a NOP sled into equivalent code:
