Solutions to the 15th mission* from my livestream.

Slides (clickable links): goo.gl/VXNRSK
Special thanks to foxtrot_charlie for making them!

Security Days photos were made by the Security Days staff.
Btw, you can find the Security Days tasks on Mateusz Kocielski's (one of the organizers of the editions I took part in) github:
github.com/akat1/securitydays

* Missions are simple CTF-like challenges that I post at the end of (almost) every livestream. After one week the submitted solutions are gathered and I make a summary video like this one.
