So we have OSINT Challenge called Photographs! https://photographs.ctf.intigriti.io/
We downloaded the image and ran exiftools on it and found an interesting make of the camera but also a artist name: “fl0pfl0p5”
So if we google “fl0pfl0p5” we will got some hits
About.me , Twitter and Reddit.
It was on reddit we found some interesting information, a new name:
Someone called “m4r64r1n3” https://www.reddit.com/r/DailyCodingDose/comments/15l73xa/github_profile_readme_generator/
He had created a user on github named: “fl0pfl0p5”.
Sadly i looked through commits, history and everything but did not find anything interesting. So then i did a google search on “m4r64r1n3” because new information right?!
Did not find anything interesting on google, some pinterest and other stuff, but did a search on twitter/X as well and did find a user “m4r64r1n3”
There we found a new photo as well!
Really nice photo, so lets reverse image search it!
Found a reddit post: Reddit and a new name: “v1ck1v4l3”
But we found a third picture in google, this was for the blogger platform:
https://v1ck1pictures.blogspot.com/
I downloaded the image, it was called IMG_3674.jpg” so hopefully metadata.
Confirmed that we are correct, Artist: “fl0pfl0p5”
But no flag except a comment on the blogpost:
“I don’t think it’s a good idea to share your location online.” But i could not find any GPS coordinates or something similar.
Maybe it was edited? Let’s use wayback machine!
Found the post and a flag:
