RE Crypto I managed to exfiltrate a highly classified, encrypted executable, but no tool I throw at it can parse it. It doesn't even have an ELF header!

Fortunately, I also managed to exfiltrate the custom Linux Kernel Module (loader.ko) that the target system uses to execute these files.

How does the executable run without an ELF header? Does the kernel module have something to do with it?
