This is a Rev challenge the only one in the competition I’m new to Reverse Engineering but this one was pretty easy

Solution

First I unpacked the binary using upx UPX (Ultimate Packer for Executables) is an open source executable packer supporting a number of file formats from different operating systems. It is used for compressing binaries too. So let’s unpack first
