Buffer overflow on Stack | Memory Overwrite | RIP alteration | A visual comprehensive explanation.
Buffer Overflow: A vulnerability that exists within a code, that has no failsafe when arguments supplied to the program are bigger in size than allocated. In that case, Exceeding values overwrite the stacks.
To attack such vector, one can overwrite a specific value, for example making a value appear true that should have been false, AND/OR changing the flow of execution by altering the Instruction Pointer.
This lesson is divided into 2 videos.
1) Visualizing buffer overflow,
2) Attacking the same vulnerability but maliciously (Educational)
I know my videos shouldn't be this long, as what I say can be done in half the time, but I try to repeat everything in such a way, that it can almost visualize the concept for the eyes of the viewer.
I really hope that I can make a change out there by trying to visualize concepts that are only written in pen and paper.
I don't have money, So if subscribers can someday reach 1000, Maybe I can put something onto my plate by myself. So, If you really like the video, Make your subscription count.
Thank You ...
