Executing the 32-bit ELF executable, bin, found in directory ./trash, within leviathan4‘s user directory, returns a string of binary characters. There are plenty of tools that can be used to translate the binary text to ascii characters, and in this instance I used Perl.

leviathan4@leviathan:~/.trash$ ./bin | perl -lape '$_=pack"(B8)*",@F'
