    Any nudges for this one? I have figured out a method to write to memory addresses in the stack but can't really figure out where/how to get to the flag.

    Hi guys. I think i miss something in this challenge. I leak anything in binary and can write anything anywhere, but i can't found a solution to manipulate/stop the infinite loop.

    ROP failed due to infinite loop.
    GOT Rewrite failed too due to Full-Relro.

    I have leak the PIE, the canary and the libc base address.
    This binary seem to be easy ....

    Can someone help me ?

    Thanks in advance
