Challenge Description#

Given a 64-bit ELF executable named ngestring.

Analysis#

The challenge name “ngestring” is a hint - it’s Indonesian slang suggesting we should use the strings command.

$ file ngestring
ngestring: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, 
BuildID[sha1]=..., for GNU/Linux 3.2.0, not stripped

Solution#

Simply run the strings command to extract printable strings from the binary:

$ strings ngestring
