Exif
The main idea finding the flag is to have Exiftool.
Step-1:
After I downloaded Computer-Password-Security-Hacker - Copy.jpg, I immediately tried to open it using Exiftool.
Step-2:
If you have some experience in CTF before, Exiftool is quite widely used. So I input exiftool Computer-Password-Security-Hacker\ -\ Copy.jpg
Output:

Step-3:
Voila! I got the flag there. I don't have any idea why this challenge was in hard.
Step-5:
Finally the flag becomes:
