Description: My friend sent me a clip and I found it to be very interesting. I wanted to watch the full video but before I could rewatch the clip, he deleted it!! All I have right now is this image he sent me afterwards. Can you help me find the video link?
This question starts with a jpg file, starting with some basic analysis, everytime I got this string in License of the image which kept on bugging me, also while analysing common passwords of this file I got few terms like,
AAA-7Z-EC32-D32, chevalo reviens and Klemou Was Here
Also, when I tried decoding that string I got in license
IFAUCLJXLIWUKQZTGIWUIMZS
I found out it was a Base-32 decoded plain text which luckily decoded to again this,
AAA-7Z-EC32-D32
After this, I was sure it is some password to steghide or something!!
I tried steghide with this password and got a secret.zip file which had two images,
Finally, the question itself gives a hint “XOR”
gmic n1.png n2.png -blend xor -o result.png
I used this command to XOR both the images and it resulted the FLAG
