What is this file ?Can you find hidden flag ?
Flag format: YUBITSEC{}
### Solution
Using [binwalk](https://github.com/devttys0/binwalk) to analyse the downloaded [file](https://github.com/kipyegonmark/ctfs/blob/master/YubitSec-2017/File/File) reveals a collection of zip files.
Running __binwalk -e__ to extract gives another zip file. Repeating the extraction process eventually leads to folder labelled __last__ that contains [flag.png](https://github.com/kipyegonmark/ctfs/blob/master/YubitSec-2017/File/flag.png) which has the text __C0MPR3SS10N_1S_G00D__.
FLAG: __YUBITSEC{C0MPR3SS10N_1S_G00D}__
