First off, thank you so much for creating this github. Your solutions have been very helpful, but we are having a lot of trouble with phase3. Is the rsp+0x28 increment standard for all attack labs? It seems to change from person to person, but we aren't sure how to determine our increment. We have tried 0x28, and it's not working.

I'm on phase 2 of the lab, and I have to inject code as part of my exploit string in order to make the program point to the address of the function touch2(). I've gotten the correct exploit code I need (confirmed with TA):Phase 2 involves injecting a small code and calling function touch2 while making it look like you passed the cookie as an argument to touch2 \n. If you look inside the ctarget dump and search for touch2, it looks something like this: \nPhase 5 is similar to 4 and you have to use ROP exploit in order to solve it but the points awarded for this specific phase aren't worth\nthe effort as mentioned in the instruction.
