Toddler's Bottle - flag

Only a binary file is provided: http://pwnable.kr/bin/flag

Load the binary file to DIE(Detect It Easy):The file use UPX packer.

So we need unpack first: upx -d ./flag

Then see the file content and find the flag: strings ./flag > output.txt

The flag: UPX...? sounds like a delivery service :)

You can also use gdb to get the flag after unpacking the binary file.
