Newly discovered campaign takes advantage of the fact that most vulnerability scanning tools don't read compiled open-source software.

Python scripts are compiled to cached bytecode to speed execution. As a result, many optimizations of Python have focused on making the bytecode faster to parse.

Security researchers at ReversingLabs have discovered a novel attack that used compiled Python code to evade detection. According to ReversingLabs reverse engineer Karlo Zanki, this could be the first ...

Scripts can also be pre-compiled to Python bytecode (so-called .mpy files) to enable faster loading at runtime. – Via frozen code: Once an application has been developed it can be pre-compiled ...

This code can be run from RAM, EEPROM, or even external storage like an SD card. Recently there was a supplemental compiler project that even takes Python code and compiles it into VM byte-code.
