In this challange we are again working with the same picture we had in Notes
We are given the following information:
The hacker claims we have planted this note on his phone. Can you find out the actual date and time when it was last modified?
The flag format is: EPT{31.12.2099_23:59}
P.S: This is not an artificial challenge - this timestamp is indeed added by the notes application and can be recreated easily on your phone.
By using StegOnline and messing with the settings we can see that the creation of the note becomes visible.
Convering this to the flag format gives us the flag EPT{30.05.2011_06:45}
