In this episode Omar Ashour and I (Chris C.) solve the No Padding, No Problem picoCTF challenge. It takes us a while as we try to remember how RSA works and figure out the weakness and formulas we need to us.

We leave our struggles in the video so people don't feel like they are the only ones who can't figure something out in 10 minutes. That said, you can watch the beginning then jump to 1:25:00 - where Omar Ashour figures out the formula to use.

We record live every Monday morning around 10am-ish Mountain Daylight Time and invite you to join us. If you do join us, feel free to ask questions in the chat, and we will do our best to answer it. You can also send questions and other feedback to [email protected] or in the comments.

Thanks for watching!

SaturdayMP Show 66: picoCTF Format String 2 (Solved in One Long Video)

https://youtu.be/3dNMOff-Gp0

In this episode I solve the @picoCTF Format String 2 problem in my longest video yet. Jump right to the end if you want to see the solution which used pwntools.

I think it gave me the knowledge to solve Format String 3, which I haven't solved yet: https://youtu.be/AT8w2fsgzsA. That said, I'm still struggling to picture the layout of variables on the stack.
