Nuit de Hack Quals -2014 Here Kitty Kitty!

Not much flags this time too..Managed to get 3 of them and will write however i got it.
Question:
Mirror Link : http://1drv.ms/1jjplOH

So well first thing we would think of is audacity.Lets try our luck..You get a weird waveform.I just zoomed in to see the waveform.I got a view of Morse code,before which i thought it was a binary . Dont zoom in much coz you would over think as binary numbers.It would look like this :

Note down accordingly and you would get this Morse code

..... -... -.-. ----. ..--- ..... -.... ....- ----. -.-. -... ----- .---- ---.. ---.. ..-. ..... ..--- . -.... .---- --... -.. --... ----- ----. ..--- ----. .---- ----. .---- -.-.

Decoding which will give a md5 hash : 5BC925649CB0188F52E617D70929191C
As the flag was case sensitive and was lowercase so the flag would be : 5bc925649cb0188f52e617d70929191c

Flag : 5bc925649cb0188f52e617d70929191c

CSCamp CTF Stegnography-1

As the portal has been closed i cant get the exact questions,but i have files.So you can try out.

STEGNO-1

There was a file to download and the hint given was "your eyes are blurry"

file download : https://www.dropbox.com/s/kop94gfre3chvzb/stega1.png

It was 50 points.Simplest one.

Open in paint and use the "fill with color" option.Select any color you want apart from white because you cant see properly.


Can you see this now ?
The Flag is {Are_you_color_blind}
