Problem: I’ve found this java program on someone’s computer that looks fishy.
Hint: I wonder, is that really Java?
The hint leads us to believe that that program is not actually a Java program, which can be confirmed by trying to compile the program in Java.
If we Google the term whitespace, we find that it is a programming language.
Next, we can search Google for a whitespace interpreter. We used the one found here.
This interpreter has an upload option, so we just upload the program and click Exec.

What is this magic? My file is here, but where are my hardcoded strings?
We are given a Mach-O 64-bit executable x86_64 which can be run on Mac OSX devices.
First, we can run strings on the file to see what strings are hardcoded into the file. This gives no output.
Next, we can decompile the executable by using this, which was given in the hint.
Then we run sorcery through gdb.
